An exception is introduced in the code that plots
MeshesContainersto be able to plot it if any of theMeshedRegions in the container is empty. While working lately with isocontours in distributed, it may be the case that an isocontour does not pass through a given partition of the spatial domain. If that is the case, the isocontour mesh for that partition is an empty mesh (as it should, with 0 nodes and 0 elements). If all the isocontours are stored in a MeshesContainer, you end up with several meshes being empty and some not. As a user, I'd like to domeshes_container.plot()and still have a plot. This PR enables that.Tested interactively with a
MeshesContainercomprised of entirely empty meshes and a white pyvista plotter pops-up (as it should).
