Q.
When running a spectrum (DDAM) analysis in ANSYS 9.0 on a Windows 2000 or XP system, ANSYS aborts with an Unhandled exception in ANSYS.exe: 0xC0000005: Access Violation error in /POST1 during the modal combination phase. The error occurs when using two processors (/config,nproc,2). For Linux systems, ANSYS aborts with a Segmentation fault error. Note, the error does not occur when using just one processor.
The model consists of BEAM188, SHELL63, MASS21, BEAM4, and COMBIN14 elements.
A.
The above error is caused by an unintialized number in the SMISC record for the BEAM188 elements. A number such as E-311 is used and ANSYS aborts in the load case combination phase when it tries to multiply it. There are two possible workarounds:
1) replace the BEAM188 elements with BEAM4 elements
2) suppress the writing of the SMISC records for BEAM188, e.g. in the expansion pass before the solve:
outres,erase
outres,all,none
outres,basic,1
Another possible workaround is to run the analysis using just one processor, however, using just a single processor will not quarantee a successful solution.
This error has been fixed in ANSYS 10.0
