Simulation Setup error

[goncalves]

Hi @farahamiruddin,

Thanks for posting your question!
Could you please share the project link here? It would be great to take a close look at that. But for now, if you’re trying to setup an incompressible flow analysis, please take a look at this topic below.

"A setup regions is being used in a single-region analysis type"

Hi! The issue here is simple: under normal circumstances for incompressible analyses, we need a single volume, representing the flow region, to run the simulation. If your CAD model has more than 1 volume, you will run into multi-region errors down the line. [image] The flow region, as I mentioned, is what we want. Solid1 is the part causing issues. The remedy here is very simple: head back to CAD mode, create a delete body operation and delete solid1. [image] The resulting model should b…

best,
