Dear all,
I want to conduct dynamic stress calculation for an impeller. I have applied the pressure loading to all airfoil element faces. Based on the modal analysis results, I can move to dynamic stress calculation for certain modes of interest if I can calculate the nodal force that is applied to the master nodes only. The nodal force must be "equivalent" to the element pressure loading.
Does anybody know how to convert this pressure loading to the equivalent nodal force on the pre-assigned nodes? I can write a standalone program to do it, or write an ANSYS program using APDL? Many thanks in advance.
