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.

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.

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.  

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?)  

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.

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.

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.

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.

President

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

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

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.

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.

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

Desing Engineer

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

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

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.

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.

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

Design Engineer

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

Mechanical Engineer

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

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

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

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.

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?

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

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!

Lead Mechanical Engineer

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

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.  

Student

Takes minutes to open simulation results.

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

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

Engineering Director

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

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.

integration engineer Analyst

Engineer

Easy to learn and useImmidiate support is great to progress quickly

The user interface is intuitive and easy to use.  

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

The default Numerics seem to work most of the time.

CFD / thermal consultant 

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

Senior Process Improvement Specialist

It was a very pretty way to show simulations that have real potential to be useful to show off to champions and project sponsors.

Industrial Engineer

There's an online community where the developers will answer, in detail, any question asked within an hour. And they will work with any user directly on their model to resolve issues.

Something as simple as making an operator in the model pull a single box off of a pallet that's in a rack took a week and multiple questions to figure out and required programming multiple objects in C++.

Senior Project Engineer

What I liked most about this software was what I saw in a presentation that was able to simulate a logistics warehouse and was very helpful and informative for future clients to see actual 3D modeling showing more than be stated just in words.

Bringing in a 3D model for a machine can be frustrating, due to the way sizes are defined.

So you have to designate paths and boundaries which can eat up processing speed.

The customer service has been phenomenal and they're constantly pushing out revisions to improve the user experience and add features.

Senior Engineer

When learning FlexSim, I noticed that the learning curve was much shorter than other simulation packages due to the auto-script creation.

I really enjoyed using FlexSim for modeling fluid manufacturing systems.

It provides a large platform to model with great detail and precision.

Any environment that can gain knowledge with simulation modeling should vertainly make use of flexsim.

It allows me and my colleagues to get a good grasp on how a project should look.

You can do basically any thing you could possibly need in regard to simulation building.

Project Support

As an Industrial Engineer, being able to simulate production lines or a plant is essential to be able to analyze future improvement implementations.

Real-World simmulation at your finger tips.

There is nothing that I dislike, however, I consider that the graphics could be improved a little, but nothing that affects the purpose of the software.

To be able to make an infinite number of improvements or alternatives that can make your processes better.
