Hi,
I've made a mesh by salome.And there're some errors when started to run in ElmerGUI.

Now I have no idea about what happened,thanks a lot.

Re: errors when running solver
Hi,
your mesh has a problem, there are degenerated elements in it.
Try to make a slightly coarser mesh and rerun the simulation.
HTH,
Matthias

Hi,
Thank you,I'll remake it!
Wish it works this time!

Re: errors when running solver
Hi,Matthias
I've made some of new mesh with lager size but,the error still happen.
The biggest part of model is 500 and the smallest part is just 10.I'm wondering if it is the key of this question?
Here is the UNV file of the newest mesh(It's a model of a part of a building so exactly become heavy).
Thanks for your kind help.

Re: errors when running solver
That is a lot of materials. I took the model posted and did this it ran fine as one material. Perhaps it is in the material definitions. Perhaps post your sif file
Re: errors when running solver
Oh I'm sorry that I loaded the wrong mesh.
But it still doesn't work,maybe there's something wrong with boundary condition?I was supposed to making a thermal convection and radiation surface.
It became like this:

Re: errors when running solver
I will study the sif, but I turned on a radiation boundary and it still worked.

Re: errors when running solver
I took your sif file and ran it with the mesh you posted and got this result
although there were some errors in the log

Re: errors when running solver
I was mistaken on the errors your case.sif with your mesh ran fine attached is the solver log
