Hello,

I am conducting a transient thermal analysis for an additive manufacturing process using ANSYS APDL and would like to create an algorithm for mesh coarsening. Previously, I used the VCLEAR and VDELE commands to delete elements and then recreate coarser ones using VEXT. The nodal temperatures from the previous elements were stored and reapplied to the coarser elements. However, this approach requires leaving the /SOL processor to enter the /PREP7 processor and then returning to the /SOL processor to resume the calculations. This results brings a significant computational cost, making my current model unsustainable.

Is there a way to achieve mesh coarsening while remaining within the /SOL processor to avoid the cost of reading and writing data between different /SOL processes?

Thank you very much,

Leon

Hi,

You will need to exit the solution to remesh.
