Hi everybody,

I am using therm 7.7 and 7.8 to do a building project. I tried to draw the geometry and also to import it from dxf file but every time I run the simulation the error says "Problem in meshing the model". I have tried also to set a quad tree mesh parameter higher. I really don't know what to do. Here you have the file that I made by drawing it.

I hope someone will help me.

Hi Claudia,

I tried to change your BCs with other and your file works fine. I think the problem is due to an incorrect definition of your BCs, because the values of Hc are set to zero. Fix them considering that typical values are 25 (W/m2*K) for "external" environment, 7.7 for internal vertical walls, 10 for roof and 5,9 for floor. Refer to UNI EN ISO 6946 for complete description. Set the quad tree mesh parameter to previous value, because it's not the issue.

Hope it helps

Ciao

Diego
