FlexSim
The most powerful, capable, and easy-to-use 3D simulation software. FlexSim lets you model—and improve—existing and proposed systems.
xMarkVisual Validation
The first level of model validation, where you visually confirm that the system is working—or not working—as it was intended to.
- Model a real system in our native 3D virtual environment.
- Account for real-world variability with FlexSim’s vast array of statistical distributions and random numbers.
- Run simulation using the model to test “what if” scenarios—without needing to change things in the real world.

Our 3-axis layout and CAD drawing import help you maintain the exact spatial relationships in the actual system, so travel and transport times will be accurate.

Import custom 3D objects to replicate the look and feel of the actual system. Plus all realistic visual effects, like shadows and lighting effects, are ready to go by default.
Model Building
FlexSim toes the line between ease-of-use and capability to model even the most complex systems.
xMarkStatistical Validation
The second level of model validation, where you evaluate data from one or many simulation runs to verify that the system is operating as expected.
