[Getfem-users] Open mesh

[GUILMIN Anne-Lise]

Dear all,

 

I am working with an open mesh: I add convexes to the mesh before each new increment.

I would like to keep the values of my model variables from one increment to another.

As the mesh changes, the numbering of the dof may change too. Is there any predefined function to interpolate the old values on the new mesh_fem?

You may have already met this problem when refining meshes.

 

For now, I construct a new mesh_fem, then new vectors of variables from an interpolation of old ones on the new mesh_fem, and finally I overwrite the old meshfem and variables in the model with the new ones.

This works well with my main variable but not with lagrangian multipliers:  the computation stops due to an error of context of the model after updating the partial_mesh_fem on which are defined the multipliers.

How could I update a partial_mesh_fem and still get a correct context for my model?

 

Thank you for your help.
