I am giving a prestrain to the spheroid to see the cracks generating in the outside cuboid. Though till now I am not able to find how to initiate a crack in Ansys, I tried to make a Semi-Elliptical crack by looking at the maximum principal stress and therefore giving a crack as Semi-Elliptical following.nnActually, there is more than one spheroid, it is because I want accuracy in the results so to get good meshing around inclusions I added the spheroids. As you can see the outer spheroid in the following figure is part of cuboid i.e where I try to find out crack propagation. The cracks should be on the surface of the second spheroid as I put you can see.n<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/223\/A7WXCDXBHRYZ.png\" width=\"1186\" height=\"475\" \/>nnBut when I try to mesh the cracks the following message is shown.n<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/379\/HGOPBM4I73L1.png\" width=\"373\" height=\"184\" \/>What I am doing wrong?nCan anyone guess what is the problem?
