I am running crystal plasticity simulation in Damask. I am carrying compression deformation on a 3d geometry having 300 number of grains. My final aim of deformation upto a final compression of 0.9 . I have achieved up to total compression of 0.3 without any convergence error.but beyond this deformation I am facing the problem of convergence in Damask. Solving this Issue previously Damask developer shared a paper about adaptive re-meshing. The paper is very informative and increased my knowledge about solving convergence issue in Damask. Basically they are using two methods for solving convergence issue in damask "The mesh replacement method and the mesh distortion control method" although i have understood the procedure which they follow for establishing the above two methods.Now i am trying to follow one of the above methods to solve my convergence issue But due to my limited information, I need guidance about how to re-mesh my deform geometry in order to get undistorted mesh. 1). is there any method available in damask to achieve this re-mesh geometry? 2). how can we re-mesh our deform geometry? 3).Can we achieve mesh distortion control method by only changing the input loading file, if it is then how? any help regarding this will be appreciated
Dear Tariq Ali
I am a new user of DAMASK. I have the same problem in simulaion of large plastic deformation. I also read the paper about adaptive re-meshing method for solve this probelm. However it is difficult for me to implement it in DAMASK due to my limit knowledge. Do you get the guidance about how to implement the re-mesh setting for large plastic deformation in DAMASK? Or you have solved this probelm? Can you share it with me if it is convenient? Thanks for your help!
Dear jiazhen he
I was facing the problem of large plastic deformation and according to damask developer that they will implement remeshing technique in the upcoming new version of damask but still it has not been launched ,may be it take a little bit longer time for launching. My problem has not solved yet I have done compression upto 60 percent using phenomenological crystal plasticity but further compression does not achieved. It means I have not found out proper solution till now.
Thank you
