Create FEM mesh error

[mshavliuk]

Description

Cannot compute the FEM mesh for the multicompartment_head_project with some specific resolutions.

Steps to reproduce

1. Import the scripts/scripts_for_importing/multicompartment_head_project/import_segmentation.zef
2. Go to the mesh tool
3. Set Mesh Resolution to 10
4. See the error

Error using zef_point_in_compartment (line 128)
Arrays have incompatible sizes for this operation.

Error in zef_mesh_labeling_step (line 31)
I_1 = zef_point_in_compartment(zef,reuna_p{i_labeling},reuna_t_aux,nodes(I_2,:),[compartment_counter n_compartments]);

Error in zef_create_fem_mesh (line 148)
zef_mesh_labeling_step;

Error in zef_create_finite_element_mesh (line 11)
zef = zef_create_fem_mesh(zef);

This never happens for some other resolutions, for example 3mm. Also, on the screenshot it can be seen, that the error occurred during "Labeling of compartment 8/35", so some of them were processed successfully.

Expected behavior

The FEM Mesh generation is completed without errors.

While exploring this error, I also got another one a few times, although I'm not fully sure what was the exact sequence of actions to cause it. It might be that it's caused by an incorrectly generated mesh and be a direct consequence of an error described above, but I'm not totally sure. @GitFernandoGalaz could you take a look?

Unrecognized function or variable 'I_global'.
