Periodic mesh in a .xml file converted with dolfin-convert

[violetus]

Have you tried msh version 2 (ASCII) ?

Problem converting file.msh (from gmsh) to file.xml

Hi, are you exporting your mesh using msh version 2 (ASCII)? I think that dolfin-convert only works with that version of msh format. Cheers, Rodolfo

Also, please consider reading -

Importing mesh from gmsh 4.7.1 to dolfin 2019.2.0.dev0

Dolfin-convert is no longer maintained, and meshio is the recommended way of converting meshes. See for instance: Transitioning from mesh.xml to mesh.xdmf, from dolfin-convert to meshio - #155 by dokken Or Why to update from dolfin-convert to meshio? - #4 by dokken
