HyperFEA with NEI
« on: April 17, 2013, 02:01:34 PM »
I'm using HyperFEA with NEI Nastran V10.1 and am getting the following message: "The FEA results file was found, but element forces were not located."  It is reading the initial result file "static.els" in fine, but isn't finding the forces in the "static_i.els" file.  And, the static and static_i files are exactly the same size.  Any thoughts on what I'm doing wrong?

What version of HyperSizer are you using?

I think HyperFEA is performing its own check for element forces in this version. I believe it is mistakenly looking in the *.OUT file for results. If you can print forces to the *.OUT file (as well as the *.ELS file) it should work.

I'm using Hypersizer version 6.2.40.  Do you know how to request the forces to be included in the .out file?

Try the following in the case control. You should get forces in OUT file, and as long as you have NORANBINARY selected you should get the ELS file.

Code: [Select]
CEND
  DISPLACEMENT(PRINT) = ALL
  FORCE(PRINT) = ALL
SUBCASE 101
  SUBTITLE = UNIFORM PRESSURE
  SPC = 1
  LOAD = 1
.....
