Hello,

Thanks for the quick and comprehensive replies.  So to clarify what I mean with “as the calculation progresses”, my current approach is to exit the /solu processor and coarsen the mesh in the /prep7 processor before going back into the /solu processor to pursue the calculation. The nodal temperature are saved in an array and re assigned between the different /solu steps. So far this approach prove to be very unefficient because of all the read and writting involved to transfer the results between the different /Solu. To give a bit more background I am simulating an additive manufacturing process involving the deposition of layers of material, for that, the element birth and death technique is used. I am trying to explore the possibility of using a finer mesh at the top surface of the model, but my challenge is that the top surface changes over time due to the activation of new element layers. As of right now the model is created with a refined mesh and the central elements are coarsen as new layers are deposited.
