I would like to expand the diameter of an existing hole in a 3D tetrahedral mesh using the Morph functionality in HyperMesh 2019.1. I have been able to do it in a 2D mesh using the "alter dimensions" panel, but have struggled unsuccessfully to do the same for holes in 3D mesh. The attachment shows one such hole, and note that it is actually a second order mesh even though it looks 1st order. The model doesn't contain any geometry (solids/surfaces), so is there a way of morphing the mesh without it? how should I go about this please?
