SimScale has a very fast response and they not only answer the specific question that is asked but go into detail about why a particular feature works the way it does.

Mechanical Engineer

I like the cloud computing feature the most as well as the really quick and helpful customer support

WSP, ARUP, Thornton Tomasetti, L&T, and many other companies in AEC are using cloud-based CFD simulation with SimScale to virtually test building designs.

Building Simulation Engineer

The mesh generation is also impressive, as it can be much more forgiving on complex geometry that we use,  and for any issues, the documentation is extensive available online, along with great customer support.  

Building Performance and Sustainability Specialist 

It is intuitive and easy to set up the simulation, the software reads our 3D model accurately, lowering CAD clean up times, and hence was easy to integrate in our design team workflow.

Chief Engineer

I see a lot of potential in Simscale, is a really good modeling tool and has a lot of tutorials and a quick answering customer support.

Also, I can keep using my computer for other things like making a report or editing the geometry for a new design.

Simscale has been a great tool to simulate design massing and analyze site conditions.

I also like there there are courses from SimScale directly that teaches us not only the way to use it ; but also guides us on projects that can be done with it.

The parameter configuration process pre-simulations is very intuitive and ordered, akin to a structured list.

We are very happy with SimScale, as it is an affortable solution for product development and testing and allows access to quality simulations without the hardware and time limitations.

The cloud based simulation is quick and offers meaningful data visualization.

Computational design lead

There are coming ways through API and Rhino plugins but we haven't been able to utilize it 100% yet.

Product Development Engineer

I have not jet learned how to link up the CAD model to the Simscale model in such a way that modifications in the CAD model can be used to "regenerate" the flow volume of a CDF model (if it is possible at all?)  

Design Engineer

The option to edit a model in CAD is nice too.  

CFD Engineer

in addition to this feature, i liked how fast we can get the simulation done , generally CFD simulations are taking time but here in simscale , u can have your results ready within some hours.

It also seems generally popular because I was talking with a mechanical engineer the other day and he was also talking about how he did a project on SimScale.

Maybe Simscale should include in the future shell and beam elements.

The SimScale modelling results help me quickly design new and unique heat transfer devices.

Principal Mechanical Development Engineer

To increase the user base of CFD someone has to come up with more obvious terms and explanations in this space, e.g. when is it best to use Gauss Linear Limited Corrected instead of Gauss Linear Corrected?

Now we can focus on design rather than the engineering behind.

Assistant Manager

The 3D dynamic flow areas and the rotational area are a bit confusing to understand in the beginning with the reference content that is available.

Creating Pedestrian Wind Comfort simulations is easy for everyone!

engineer

Maybe viewing the 3D model should be more intuitive

It's been intuitive to use after a walkthrough with my coworker, and what I haven't understood I've been able to ask SimScale about directly.  

Reliability Supervisor

I've been able to either work through challenges myself using the readily available documentation or as a last resort reach out to the customer support for a quick resolution.

lab engineer

I would need different colors in parts ( possibility of change part colors) to set easily the contacts

The rotary machine analysis is a key feature (MRF rotating zone) in my case.

Yes, sometime as user i feel that i am not able to fix the simulation file/model when it is failing to run and i have to take help from customer support.  

Stack Mechanical Engineering

You can also download the results and post-process in ParaView which is very helpful and opens up lots of options.

Desing Engineer

That does not bring a CAD designer, it is only simulation, few post-processing options

Engineering Director

We gained the insight by simulations we ran, which helped us to optimize out product in short time.

Lead Engineer - Mechanical

More CAD operations would help (example would be to split just faces instead of bodies).

Sustainability specialist

Simscale is a fast and rather easy simulation software to use, whereas it gives accurate and reliable results for PWC analyses.

Plant Project Engineer

So far with little experience I have been able to get good results that I could validate to ensure I understand the constraints and inputs I am using.

SimScale has made a cloud native simulation platform that works seamlessly.

here, in Simscale , due to it's navigator form, u don't need to worry about the checklist.

integration engineer Analyst

It helped us to move quickly with the help of knowledgeable support engineers.

The default Numerics seem to work most of the time.

Team Leader

I want to ask a question through the messenger, but it is difficult to ask a question because my English is not very good.

CFD / thermal consultant 

However, they are very responsive and take note of your recommendations to incorporate them in future releases.

The workflow is easy to understand and only a few introductory tutorials are needed to get up an running.  

For many applications, compared to other software, its cost-effectiveness stands out.

Lead Mechanical Engineer

Ease of use and implementation has made using SimScale software a success at DTS.

Student

Takes minutes to open simulation results.

Units have been a little difficult for me to work with.  

Easy to use and calculation "power" with remote Processor.

Entrepreneur

You can specify specify forces and moments and/or area averages to monitor statistics across specific faces of objects and also obtain statistics using post processing simulation results using cutting planes and particle traces.

the interface to the cad model is relatively easy to use and straight forward.  

Good support, tutorials and worked examples.

Some reviewers find CATIA’s cost significantly higher than alternatives, mentioning expensive licensing, high maintenance fees, and extra charges. Users say the price is prohibitive for small businesses, and most indicate value for money is a concern.

Value for money

By industry, CATIA reviewers are most commonly professionals in automotive (41%). The most frequent use case for CATIA cited by reviewers is engineering CAD (96% of reviewers).

Technical consultant

There is a steep learning curve, which is to be expected due to the amount of functionality. Once the basics are understood it is straightforward.

Testing project manager

I really liked the tool, with a bit of preknowledge and time, you can handle the features that are interesting you and I was able quickly to do what I needed in different features but I quickly understood that I was using only 10% of the tool.

This is a really powerfull tool allowing to do almost everything that you want around the design in general.

Engineer

My overall experience with CATIA is that it’s an exceptionally powerful tool, but one that demands a serious investment—in both time and resources.

CAD Designer

Clearly the shape design is the best tool box that you can have on it.

Senior Technical Officer

Catia is one of the best CAD/CAM/CAE software in the industry.

Apart from this the users have to renew the license each year.

Project manager

Comptablity between differents version of Catia can sometimes pose challenges when collaborating with others or sharing files

Software Engineer

Loading of wishes and data format conversion should be replaced by local storage so that performance is inconsistent throughout the process to adapt to each company's changing security standards.

Solution Architect

Approach of designer becomes easy and putting thoughts on paper can easily model into 3D. Saved a lot cost of prototyping and time to market.

Lecturer

It is also highly customizable, so this will allow users to tailor the software to their specific needs.

Project Engineer

The software has a steep learning curve and requires a high-end computer with advanced graphics capabilities.

It also allows users to customize the software according to their specific needs.

It is a powerful and versatile CAD/CAM software used by many industries for product design and development.

Using the FEA analysis on CATIA resulted on more accurate results than other options that we used, drafting module also let you build more flexible drawings.

Engineer Trainee 

The CATIA helps our organization to create part modelling and assembly modelling as per requirements with short period of time.

Honestly i dont see any limitations of this software other than Cost which make sense for larger organization but smaller organization cant afford.

DevOps Developer

All-in-one Computer-Aided Design software to build different objects models and structures with advanced shape modelling capabilities.

It is also not compatible with all operating systems, making it difficult to use on certain platforms.

The downside is that this software is very expensive, so it makes it difficult for smaller businesses to afford it.

Researcher

It is strange that Dassault has worked so hard to improve UI on SolidWorks yet barely did on CATIA.

Editing the component in the assembly is now made easy.2D Modelling (Draft review) is easy.

Training assistant 

CATIA is not the software that I strongly appreciated compared to SolidWorks, which I really liked and find much more suitable for my current work.

Netbackup administrator

Just a little slow and needs a fast process computer to worl on a effective note.

Quality Technician

I like the most about this software is to easyly create object and model by measurements

Experienced user might not find this an issues, but for someone switching from SolidWorks to CATIA, I definitely had a hard time adjusting.

Marketing Manager

We were looking to create complex curves for our project which turned out to be surprisingly easy.

Mechanical Design Engineer

D design is little concern about the product and needs to be considered for evaulation

The CATIA is one of the best software for designing engineering drawings as per specifications with great accuracy.

It can also be difficult to learn and use, making it difficult for new users to get up to speed quickly.

Junior Engineer

In general I can say, I am so delightful to use Catia because I can modify my drawings easily.

Senior software engineer

Understanding Catia software is little difficult for beginners.
