Re: [Getfem-users] Conductivity values definition - Getfem / python

[Yves Renard]

Dear Cristian,

You have several possibilities to define a coefficient whose value is different from a mesh region to another. If it is piecewise constant you can describe it on a P0 finite element method then you can obtain the degrees of freedom of a particular region with mf.basic_dof_on_region(rg).
With the high level generic assembly, you can define a non-constant coefficient in a more general way by it _expression_ with respect to X, the current position on the mesh (for instance sin(X[1]) + cos(X[2]) is valid).

I hope it could help you.

Yves.

Hi

i'm new using the getfem library in python and i have a question about the definition of different values of conductivity in different regions of the mesh. I had tried using the md.add_isotropic_linearized_elasticity_brick() but i didn't succed.

Which one is the best way of defining material constraints in some regions of the mesh?. I also have studied the demos but i can't find any help. Could anybody give me some advice?

Thanks

Cristian Alejandro Torres
