The interface produces by default a set of analysis control cards suitable for solution sequence 24 (linear analysis) and post-processing output requests suitable for the NASTRAN to FEMVIEW interface program. These cards are illustrated below:
$ NASTRAN CARDS ... $ NONE $ $ RESULT OUTPUT FILE ... $ ASSIGN OUTPUT2=b31box.op2,STATUS=UNKNOWN,UNIT=12 $ $ MODEL TITLE ... $ ID FEMGEN MODEL: b31box TITLE: No model title $ $ EXECUTIVE CONTROL CARDS ... $ SOL 24 TIME 60 COMPILE SOL24 SOUIN=MSCSOU NOREF NOLIST ALTER 176 OUTPUT2 CASECC,GPL,BGPDT,ECT,CSTM///V,N,IUNIT=12 $ OUTPUT2 OPG1,OQG1,OUGV1,OES1,OEF1///V,N,IUNIT=12 $ ALTER 189 OUTPUT2 OGPFB1,,,,///V,N,IUNIT=12 $ ALTER 210 OUTPUT2 OSTR1,,,,///V,N,IUNIT=12 $ CEND $ $ CASE CONTROL CARDS ... $ DISP(PLOT) = ALL STRESS(PLOT) = ALL SPC = 1 SUBCASE 1 LOAD 1001 $ $$$$$$$$$$$$$$$$$ $ BULK DATA ... $ $$$$$$$$$$$$$$$$$ $ BEGIN BULK PARAM,OUNIT2,12 $ $ ADDITIONAL BULK DATA CARDS ... $ NONE
It is also possible to replace the default analysis options detailed in the previous section with the users own preferences. This is achieved via load type 'SOL-SEQ' and optionally a result output request directory defined by the resource *.results.request (see section 1.4).
The resource *.results.request should be set to the full path name of the directory containing an ascii file in which the desired analysis control cards are placed. Each file should have the following simple free format:
$NASTRAN Nastran Statements ... . . $EXECUTIVE Executive Control Cards ... . . . $CASE Case Control Cards ... . . . $BULK Additional Bulk Data Cards ... . . . . $END
For example, the following command should be used to access file SOL101 in the results directory:
PROPERTY LOAD SOL-SEQ SOL101 1
The interface program will test for both 'SOL101' and 'sol101' on unix systems, the integer 1 at the end of the command must be included but is not used.
