Connect FlexSim with Omniverse and run simulation

I was able to connect FlexSim to Omnivese via Live Session and run a simple animation.

However I was wondering if it is possible to transfer the animation from FlexSim directly to Omniverse to run the animation without a live session? (I have not yet found any option to do so)


FlexSim 24.2.0
omniverse
5 |100000

Up to 12 attachments (including images) can be used with a maximum of 23.8 MiB each and 47.7 MiB total.

Kevin,

FlexSim cannot export an "animation" at this point. You can export a static visualization as a USD file using Tools/Omniverse Connector. I put animation in quotes because technically what you see is a running simulation in FlexSim, since simulation and visualization are not separate things in FlexSim.

You can use FlexSim's built in Video Recorder to just capture the animation, but the resulting video cannot be imported to Omniverse. What is the background of your question? Why would you rather import the animation than connect FlexSim in a live session?

Ralf,
in the live session I experienced pretty bad performance and frame rates in Omniverse (i guess its the server latency or internet connection) and some materials were not able to transfer correctly resulting in update conflicts.
Furthermore I was interested in connecting a building model from Revit (static) with a simulation from FlexSim in Omniverse and creating a flypath through the dynamic omniverse model. (In live session mode is no rendering in Omniverse possible)

Hi Kevin,

I agree on performance. You will have to have a high(est) end graphics card to make it work. Also, have you tried to host the omniverse server on your local machine to reduce server lag? Assuming you can host RevIT on your local machine as well.

Another thought: I believe RevIT can export to FBX, which can be directly loaded into FlexSim, so why not stay within FlexSim? The model will likely be too complex to render it with RTX mode in FlexSim, but worth trying.

Graphic power should not be the problem. The nucleus is local at the moment but I work via remote connection from my laptop.

My intention was to make use of the realistic graphics of omniverse. Working in FlexSim is from a technical standpoint for sure a valid option.
