Reply To: Ansys Mechanical APDL 2021 R2 crashes when applying load

[Erik Kostson]

Unfortunately this is an issue with the MAPDL UI in 2021 R2 - please use the F or FK command instead to apply load:
(/forum/discussion/32266/need-information)

so:
F,ALL,FX,1

applies a nodal load to all selected nodes in the x direction of 1 N.

or FK,1,FX,1

applies a load to keypoint 1 in the x direction of 1 N.
All the best

Erik
