How to export the deformed structure with initial stresses for next study?

Please login with a confirmed email address before reporting spam

Hi, I would like to simulate the band gap of a deformed phononic crystal. Firstly, I will simulate the deformation of the porous structure under the external load, and then, the deformed structure with initial stresses can be useded as the new geometric input for the next step. I see the details in the following blog post: However, when I use this technique, several strange lines are at the surface of the input model. Moreover, this input model has no initial stresses. So how can I export the deformed structure with initial stresses for next study? Do you have other methods? Thanks in advance. Best regards, Haishan Tang
