Hello,
I tried mesh adaptation procedure with a very simple heat equation and it seems something wrong with my basic heat problem. The geometry is a two layered wall junction and two Robin boundary conditions are prescribed as follow dn(T)=hs(T-Ts)
The heat simulation, before adaptation, is ok, but a simple mesh adapatation make the temperature field very strange.
Is there something wrong ?
Best regards.
PS : I can’t upload files (i’m a new user) but my msh and edp files can be found here
Hello,
You have to interpolate your unknown function after the mesh adaptation. In your script, you have to add u = u; on line 43, before the second resolution of your problem.
I get this following message error while using adaptmesh with iso=true

but the mesh file is ok.
using iso=false lead to a quite long computation and a very bad mesh.
I tried to use mmgmet and mmg but it seems that both alternive can’t refine the mesh ?
Best regards.
