[Getdp] Issue with Example: Magnetometer

Hi Mikail,

from your picture of the mesh it seems that you just have a surface mesh
and no volume elements in your duplicated geometry. When I was meshing
this the first time, Gmsh complained about the mesh algorithm I used by
default (I think it was 2D: Automatic and 3D: Delaunay) because of the mixture
of structured and unstructured mesh. Gmsh suggested to use the Frontal
algorithm here, which worked fine finally.
If you want to have the same structured mesh in your duplicated geometry
I think you have to specify it separately because the transfinite information
is obviously not copied by Duplicata.

Best regards
Michael

Hi Michael
I agree with your point on the mesh.  I am not sure how to duplicate the characteristic length as well when duplicating the geometry.  Do I have to specify it separately?

On my default setup, the second beam/geometry doesn't even solve.  I am not sure, if I should add an additional post-processing components to the default.

Screenshots attached.

Hi Mikail,

I’ve just simulated your file with the default values. Both geometries are solved
but the mesh for the duplicated geometry is not structured and quite coarse.
I suppose the different results are due to the different mesh.
Here are two screenshots:

Hi
I was trying to duplicate the Magnetometer example from the Onelab/GetDP website.

I duplicated the geometry.  I also assigned the physical geometry names.
When solving: only the magnetometer example 1 shows any results.
i.e. the duplicated geometry is not solved.

I have attached the files.  Could you advise me?
