Virtual Topology functionality in APDL

    • Ethan Perez

      Is it possible to merge areas in APDL similar to how virtual topology works in Mechanical?

      I have a volume with some areas that I'd like to combine in order to clean up the mesh. The desired result would be a free or mapped mesh which follows the original areas and bounding lines while ignoring the internal lines. I've tried a few things with AADD and ACCAT but they are not working as hoped. For example, AADD only works with coplanar areas and ACCAT follows the internal lines. Virtual topology appears to do the job but looks to be available only in Mechanical.

      Hi Ethan,

      Can you try node merge?

      Hi Ashish

      Thanks for the suggestion. I currently use NUMMRG,KP to merge coincident geometry but will try using it on nodes to accomplish something similar to virtual topology.
