Lead Management Engineer

I have been using FlexSim for 3 years and impressed with the progress of their development team that kept coming up with new features that make the software getting better.

Internal Logistics Engineering

The ability to program the software to work in any industry. The capability of being universal yet customize to be very specific is fantastic.

Design researcher

Overall, the software was very interesting, fun, and functional. It could transmit the operational messages and cost, and time savings effectively.

Assossiete professor

Flexsim is an excellent tool to learn the concepts involved in simulation studies that can be used in an evolutionary way, for simple models as well as for those with great complexity.

Industrial Engineer

Outside of the software the customer support is AMAZING. They always help answer any questions you have as quickly as possible.

Excellent piece of software to help me simulate the happenings of my plant to drive progress going forward.

It's ability to show concepts to those that are responsible implementing change. Helps to visualize process, especially staff and patient flow.

Managing Director, Supply Chain Practice

The tool is so incredibly complex that  it is hard to envision every being independent. I don't know if this is a criticism or just a reality.

It has been very useful in fleshing out concepts for work cell designs and visualizing process-flows, bottlenecks, etc. The customer support is the best I've seen for any software.

Principal Engineer

The users manual is a bit hard to follow, and missing some information.

I enjoy running different scenarios and evaluating operational changes and cost benefits associated with these alterations.

Student

And sometimes when i re-running again I got error again. I experienced this several times during creating my model.

Industrial Engineer Intern

It was fairly easy to build this model and I would recommend Flexsim to anyone who is looking to simulate manufacturing processes.

Industrial Design Engineer

I like Flexsim's flexibility in modeling material handling processes of all kinds and use experimentation to rapidly compare multiple scenarios. Its intuitive to use and easy to run.

I use flexsim in many Projects, but The constants upgrades and The license cost are a sérios problems.

It is a really complete software, with a lot of tools to help you simulate very diverse situations and scenarios.

Other simulation software I have used in the past is ProModel, and Flexsim is way more user friendly than Pro Model.

Assistant Professor

Strong statistics (distributions), that can be integrated on the models, collecting and presenting data. Anything you lack regarding the model or actor logic can be added as code snippets.

Treble Acoustic Simulation Suite

Owner

The support is very responsive, and I am really enjoying the ease with which design variations can be quickly assessed. The workflows are easy to get used to.

Acoustician

Very easy to use and good modern workflow. Nice and quick to switch from one scenario to another.

Senior Engineer

The software is easy and intuitive to use. The UI is good and makes organization of projects and sub-projects trivial.

Auralizer, IR download, quality of the simulation result (I trusted what I heard immediately).

Project Engineer

Treble allows for fast and accurate simulation results and helps improving confidencein acoustical designs.

There are some features missing from Treble that I am used to using in similar products.

Owner and Principal Consultant

We have had a very positive experience showcasing this software as part of our acoustical consulting practice and are eagerly awaiting forthcoming updates announced earlier this month.

When I have to place sealing speakers 50cm below the sealing it is no longer a sealing speaker as additional room reflection are generated which are not there in real.

Being well integrated with SketchUp makes it very easy and fast to create/modify acoustic models.

I had a bit of a hard time getting models into Treble from SketchUp and it is quiet sensitive to the way of modeling.

Possible ahead of the field. The organising of projects needs some work as this is not as flexible as it could be.

Chief Acoustic designer 

We used Treble actively for the first time recently. We integrated the software into the initial design stage of a project, where we utilized a number of acoustic analysis approaches.
