      I created a triangle mesh in ANSYS Mechanical and imported it into the APDL.


      When I checked the nodes in the ELIST, I saw that they were aligned CCW.

      Does anyone know why this is happening and how I can fix it?

      Is there anything to fix?  The orientation determines the element out-of-plane normal direction.  Maybe it is supposed to point in that direction - hard to tell with only one element and no knowledge of the CAD or intent.

      If the element is a 3D contact element or a 3D thermal surface effect element (surf152), esurf,,reverse will renumber it.
