Visualising 1D mesh embedded in 2D segfaults #68
Description
In Example 7 of MFEM, we look at a surface mesh: a 2D mesh of triangles embedded in 3D space.
For my own research, I want to take this a step easier and look at a 1D mesh of segments embedded in 2D space.
From the MFEM side, I think things work well enough. However, when I try to visualize this mesh inside GLVis, I get a segmentation fault. I do realise GLVis is not made to visualise 1D data, but still it may be beneficial to debug the segfault.
This is the mesh I am using:
