Hi,
I am trying to calculate the Equivalent Radiated Power of a given surface, based on a named selection. I have performed a harmonic analysis using MSUP, and have created a named selection called "LARGE".
The code has a number of blocks:
1) Time
Here the time scoping is obtained
2) NS
Here a mesh scoping is obtained from a named selection called “LARGE”
3) Skin mesh
Here a “skin mesh region” is extracted from the full mesh, based on the NS mesh scoping
4) Disp
Here the displacements at the skin nodes are extracted as a field container, for all tfreq (frequency values)
5) ERP
Here the ERP should be calculated, but I continue to get an error:
DPFServerException: erp_accumulate_results:31<-ERP input parameters are missing or badly defined.
CODE:
path = r"C:\ERPTool_files\dp0\SYS-1\MECH\file.rst"
