Hello,

I'm new to CFD, and I want to simulate the airflow in a classroom using OpenFOAM to obtain CO₂ distribution, temperature and humidity profiles, airflow patterns, etc.

To create the room, I was planning to use Salome. The classroom will include people, tables, and a heating system (located in the ceiling, which I will attempt to simulate, though it is not my primary focus).

My question is: Is Salome the right tool for this type of work, considering the mesh and complexity? Or are there other, more accurate open-source programs you would recommend?

Thank you for your help!

Yes, Salome is a good choice for generating meshes for complex geometries like a classroom. It integrates well with OpenFOAM and offers flexibility for detailed meshing. However, for very intricate features or alternative workflows, you might also consider Gmsh, which is lightweight and widely used in CFD. Both are effective, depending on your comfort and project needs.

Hello Captain Rogers! �� Thank you for your response.

I’ve created a geometry with multiple inlets. For each inlet, I started by creating a surface (either a disk or a rectangle), then translated it to the target region. Afterward, I added a thickness to the surface and cut the main box using this thickness to create the inlet or outlet. So far, everything seemed to work fine.

The issue arose when I started organizing the geometry into groups for CFD simulation. While creating groups for walls and floors was straightforward, I ran into trouble with inlets and outlets. Specifically:

I couldn’t select the inlet to include it in a group.
To address this, I tried fusing or exploding the inlet to separate it from the wall surface. This allowed me to create a group, but the group only appeared under the inlet's branch in the tree, not under the main box's branch.
If I tried to create a group under the box's branch, I encountered an error, as if the inlet wasn’t properly “attached” to the box.
So my questions are:

Is there an alternative method for creating inlets and outlets in Salome?
If this is the correct approach, what might I be doing wrong?
Thank you so much for your help! ��
