Getting the model data is abnormally long with gmsh.view.getModelData() - Python API
I need to deal with big gmsh mesh files, notably I need to pick up the data (element data or node data) which is present in the file I openned. My problem is that the gmsh.view.getModelData() method takes too much time (and even more comparing with the gmsh.model.mesh.getNodes() and gmsh.model.mesh.getElements() methods) and I can't afford that for my purpose. Here is a screenshot illustrating my problem :
Is there any way to improve performance in the way of getting model data ?
I've also encountred a warning with gmsh.model.mesh.getNodes() (only at the first call), maybe it is linked with my issue :
