MSC PATRAN Test Correlation 2

[Teos16]

Hello!

I'm trying to learn how to use a Patran tool named "Test correlation" (MSC ProCor), but I don't have much success. I'm using an official guide located in Patran directory and trying to make examples. I have a problem doing the first one (antenna, G-Set), though I'm doing everything as described in the book.

The problems are a fatal error in .f06 file and there are no any results in .op2 files to do further examples.

That's all Nastran did:
SOL 103
TIME 600
CEND
*** USER FATAL MESSAGE 149 (LINKAR)
CALL STATEMENT MODEFSRS IN SUBDMAP SEMODES HAS AN ARGUMENT LIST OF DIFFERENT LENGTH THAN THE CALLED SUBDMAP
*** USER FATAL MESSAGE 149 (LINKAR)
CALL STATEMENT MODEFSRS IN SUBDMAP SEMODES HAS AN ARGUMENT LIST OF DIFFERENT LENGTH THAN THE CALLED SUBDMAP
*** SYSTEM INFORMATION MESSAGE 480 (XSEMIN)
JOB TERMINATED DUE TO ABOVE ERRORS IN THE DMAP/NDDL LINKAGE EDITOR (LINKER)
0FATAL ERROR
1 * * * END OF JOB * * *


No Symbolic Replacement variables or values were specified.



I'd be really glad to get any help or advice! BDF and.f06 files are attached to check whether the example was done correct. Thank you.

Hi @Teos16,

In your .bdf file, there is the following line:

INCLUDE 'C:\MSC.Software\Patran_x64\20140/mscprocor_files/dmap\p
rocor.v2008'

This "included" file contains what are called DMAP alters which are needed to run the ProCor utility. These DMAP alters are, in general, solver version dependent. Notice that the file name containing the DMAP alters (procor.v2008) has the version number in the extension, i.e. v2008.

Now, in the f06 file you sent, we see you are running V2014 of the solver:

Version 2014.0.0-CL305068

However, in the directory C:\MSC.Software\Patran_x64\20140/mscprocor_files/dmap, there does not appear to be a V2014 version of the DMAP alters. So, try using the latest version, i.e. procor.v2012; it may run. If you still get bizarre messages, post back and I will take a look at making a 2014 version.

I tested the v2012 DMAP alters in version MSC Nastran 2014, but they don't run either.

I have modified the procor.v2012 file to update it to version 2014 - find attached procor.v2014 - DMAP alters are ASCII text files so you can open the file and look at the contents with a text editor, just to reassure yourself this is not a bogus file. Put the procor.v2014 file somewhere on your file system, why not in the C:\MSC.Software\Patran_x64\20140/mscprocor_files/dmap directory, but maybe you don't have write access there, in which case put it anywhere you can.

Fix up the INCLUDE statement in the input file (or modify the Executive control direct text input section in Patran, whichever is your preferred method), to point to the procor.v2014 file.

One other small modification is necessary. You named the PREGKE table data %KINETIC. Unfortunately, MSC Nastran interprets the % sign as a symbolic substitution variable; I just renamed the line

,PREGKE,1,%KINETIC,ENERGY

to
,PREGKE,1,PKINETIC,ENERGY

and your job runs now.

Thank you @dmapguru! It's very kind of you to answer and help!

Your file really made this work to be performed by Nastran 2014 and the model was completely analyzed. But unfortinately it didn't generate DPR and KE matrices in .op2 files (pregdpr and pregke) to go further. I really feel small to ask, but is there any way to fix it? I also tried to do the same example on my old PC with Nastran 2011 before you wrote the messages, but it wasn't successful unfortinately. I got the same mistakes.

You need to define the bulk data parameter POST with a value -1 not 1. In your input file, we see:

...
PARAM POST 1
PARAM K6ROT 0.
PARAM GRDPNT 999
PARAM PRTMAXIM YES
...

change the POST parameter to -1 like this:

PARAM POST -1

then you will get those outputs you are looking for. We could make the DMAP alters work for POST set to 1 as well, but this would be a bit more work. I don't remember exactly where in the Patran menus you can set this option; I'd just change the bdf file.
