FacetFESpace Segmentation fault

Dear all,

I was working with 1D HDG solver and recently I updated my NGsolve to the latest version and the definition of the Facet Space is not working anymore. When I try to define

Z = FacetFESpace(mesh, order=0,dirichlet = [1,2])

it gives Segmentation fault: 11. Do you have any ideas what is happening? It wasn’t happening in the previous versions. I attach two files - a short test.py, that is leading to the error and a 1D meshing file.

Best wishes,
Bart

Hi Bart,

are you using a package/installer of NGSolve or a self compiled version?
Which version number shows up when you start Netgen?

In the newest version on Github the problem is fixed.

Hi Christoph,

Thanks for your answer.
I’m using the package version NGSolve-6.2.1805. I will try with the new version then.

######### EDIT ############
I installed version
NGSolve-6.2.1805-93-g2f7ec8e0
and now it works!

Best wishes,
Bart
