Incompressible Simulations

Project Support
1

I am new in SimScale I really like it so far. for my graduating project i need to run CFD simulations however, I am having some troubles here.
I saw a tutorial regarding how to run incompressible simulation in youtube for architectural masses but i recieve the same error each time, here are the errors:

"Please ensure that all CAD entities are assigned a material or advanced concept. Missing material or advanced concepts were detected for the following entities: solid3

(click to select)

Invalid boundary condition: Wall 3 has been assigned to at least one body without a material assignment: solid3. Please remove this body from the boundary condition assignment.

(click to select)"

I wonder if you could help me.
Thank you.

Hİ bro I am new at SimScale too and I get this error too :slight_smile:

Hi,

The application is a bit different but if you have a look at figure 8 from this tutorial, for incompressible simulations you must delete all solid parts after generating the flow region.

For the incompressible simulation you only need a single volume (the one representing the flow region) to run the simulation. If you fail to delete the solid parts, which is what happened here, you will run into that error message.

Cheers
