Segmentation fault while Visualizing/Creating contours, slices of Lagrange hexahedron
From a post on Discourse:
Loading a 2x2x2 dimensions lagrange hexahedron element type of order 1 and trying to visualize the slices, clipping or contour leads to segmentation fault. I suspected corrupted vtk file so I created a sample element from , sources>alphabetical>unstructured grid types; Properties: dimensions- 2x2x2, lagrange hexahedron,cell order-1. I chose the default location of clipping or slicing and the Paraview closes with segmentation fault. Anyone able to reproduce this and check? This seems to be a major bug…
