Patran/Nastran doesn´t generate the .XDB file

[DavidFEA12]

Hello,

i´m doing an analysis, but when is time to get the results (.XDB file) there´s not any file in the working directory

checking the .F06 file, it says:

*** SYSTEM FATAL MESSAGE 6357 (SEP1A)
NO GRID POINTS FOUND

Someone know something about this or is having the same issue?
also is giving me other warnings:

*** SYSTEM WARNING MESSAGE 6299 (PARCPU)
NO PARALLEL PROCESS CREATED

*** SYSTEM WARNING MESSAGE 3001 (SEP1X)
THE INPUT DATA BLOCK NAMED GEOM1QS AT POSITION 2 DOES NOT EXIST.

*** SYSTEM WARNING MESSAGE 3001 (SEP1X)
THE INPUT DATA BLOCK NAMED GEOM2QS AT POSITION 3 DOES NOT EXIST.

attached are the .f06 & .f04 that the software is giving me

Thanks!

I don't see any attached files, so I can only make guesses. Does your main input file "include" other files using the include statement? If so, check for an ENDDATA statement in one or more of the include files.

Your original analysis file in the snapshot (strut.bdf) has 1 KB size.
I copied your *.f06 file and remained only the below part in the *.f06 file and saved it like that. Its size was smt like 1.04KB. So, you definitely have an include file if you have a model of at least 100-200 elements. The size of your total mathematical model (total size of bdf and other INCLUDE *.bdf/*.dat files) should be more than 1KB - probably smt at least of 50-100KB or even more depending on your model's size.

There are 2 possibilities:
- Either you have an "INCLUDE" card somewhere in your *.bdf file and you are missing it in your original *.bdf file that you are analyzing in Nastran, (or you have the "INCLUDE" card already - but the file name mentioned at your INCLUDE card is missing from your folder - you can search for this file name in your workshop folders if you can't see it in your current analysis folder)
- And/Or, (if you already have that "INCLUDE" card in your *.bdf file), you are missing parameters such as "SPC= ", "LOAD= "& others. Refer to an already compiled working *.bdf file in your Nastran folder, you will understand what I mean. You should have Nastran cards like "SPC= ", "LOAD= " & others before "BEGIN BULK" line (at the end of what I copy pasted from your *.f06 file).
- If none of the above 2 works, or confuses you, can you also upload your *.bdf file and any other file that was mentioned in your INCLUDE line of that *.bdf file here. I don't have Nastran, but I can tell what is missing if it is only a matter of Nastran card arrangements. Also some introduction of your load/bcs (force, pressure, spc, displacement etc) would help as well.

This could be due to your analysis setup in Patran. Put the following files into a zip file:

patran.ses.01
patran.ses.02
patran.ses.03
strut.bdf
strut.log
strut.xmt
strut.db.jou

and attach the zip file to your next post, and I'll take a look.
