getNodes does not return some nodes in certain physical groups
I have a mesh file (delta.1.msh) from which I want to gather the elements and nodes per physical group.
The getNodes
function does not return all the node tags for some physical groups. Indeed, look at the screenshot below: the element connectivities are correctly fetched with getElements
, but the nodes on the external boundary of the surface are not tagged in the physical group "SymmetryBoundary".
Note that the node tags are properly fetched when getNodes
is called with the default arguments, meaning that the missing node tags is a problem only for some physical groups. Here is a zoom on element 523 with connectivity [309, 390, 405, 334]
I also remark that for some physical groups, this bug does not arise. Is this a bug or I am missing something? I use Gmsh version 4.11.1.
