I have find a issue when I finished random analysis. There has stress result in "Positive crossing output" in previous version, but it's no stress result in current version. Should I type any command in input deck to request stress result for positive crossing?
The issue results from a change in the NXN 12 solver. The name of the datablock containing that information changed and therefore Femap does not read the data from op2 created with NXN 12. If you have Femap 11.4.2 and use the NXN 11.02 solver then you can read/attach that op2 in Femap 12.0 and you should see the stress data as expected. The issue has been reported and should be corrected in the next release.
