When I tried to do this, NekMesh gave the warning: "This module is designed for use with Star-CCM+ meshes only; it also requires that the star mesh was created in a certain way." Does anyone know what this "certain way" involves? Are there some criteria that, if satisfied, would allow linear meshes generated without using Star-CCM+ to be refined using CAD projection?
