Good day to all,
I'm trying to simulate honeycomb crushing in ANSYS Mechanical APDL with LS-DYNA.
The solution runs fine and I can animate the result without problem.
However, I can't get either structural forces from /POST1 and, most importantly, can't get reaction forces from /POST26.
I'm using a SHELL163 element and I tried using the manual to extract information without success.
Here's the code I'm using up to the solve command:
Sorry for the fact some parameters are in Spanish.
I'm specifically trying to get the reaction forces in the base of the Y over the analysis time with the Time-History Postprocessor, but when I try to add one of the nods for analysis the data appears to be invalid.
Also, even if I try to get the structural forces using the general postprocessor, it says that info is not available.
Can you please help me and tell me how I can get that info?
Many Thanks.
