Hi,

In model==> Equation==>Edit solver settings in Linear system am not sure about the methode to use, have you an idea about this.

Hi,

I would first solve the problem that your simulation doesnt' seem to give the result you expect. You can use the defaults as long as the simulation converges in a reasonable time without errors or warnings.

HTH,

Matthias

Could you show more of your log file if someone should tell you what goes wrong?
Without knowong more details, I would guess that this message might be related to the fact that you seem to use a 2D solver with a 3D geometry, and that the solver looks for a property called thickness which it doesn't find. Have a look into the models manual and search for the keyword "thickness"...

HTH,

Matthias

Thank you

Hi,

could you post the whole logfile?
It seems that your mesh has problems also.
And you should carefully read the chapter on the solver you are using... ;)

By "log file" I mean the output on the terminal. It will be written to a file by calling the solver like this:

ElmerSolver > case.log 2>&1

where case.log is your logfile.
Drawback: you don't see the output on the terminal.

Hi,

I cannot see what the problem is from the picture.
For gmsh-specific questions there is a gmsh mailing list... ;)
