Thanks professor, that helped. It works now. For the record I used Boolean fragments (coherence), please find the updated result figure. [image: updated tempreture.png] On Thursday, August 19, 2021 at 6:57:43 AM UTC+2 Jean-Paul Pelteret wrote: > Hi Ibrahim, > > My guess is that the mesh has

Thanks a lot for your reply, I'm working on a PHD thesis(Rostock university, Germany) in the domain of nonlinear model order reduction. the thesis is attached to a European project in the field of microelectronics. the board I attached is a graphics board and has three heat sources, 2

Hi Ibrahim, My guess is that the mesh has been exported without the connectivity between the parts being enforced. So even though the physical vertices of the mesh overlap where you have different parts, there are two or more distinct vertices that lie on top of one another and the

Dear deal.ii Community, real problem for graphical board . I used GMSH and identified different material_ids on different parts and made sure it is correct using the function print mesh info. I wrote the class Material data to substitute the coefficient function. but I tried several things
