I would like to perform a 3D fracture analysis of a volumetric model in MAPDL. My goal is to obtain the stress intensity factors for a self-defined crack geometry.
This could basically be performed with the XFEM and SMART method. I have questions regarding both methods.
To try out XFEM I enhanced example 3.8 (Generating a Center Crack in a 3-D XFEM Model (MESH200 Method)) from the MAPL help. Now I am able to introduce a crack with MESH200 elements and to perform the simulation.
My problem here is the post-processing. I am not able to access the nodes along the crack front and to get their coordinates and the stress intensity factors. Could you please give me a hint regarding this issue?
My second question. Is it also possible to introduce an initial crack in a volumetric model with MESH200 elements with the SMART method?
Thank you very much in advance!
