2 strange PATRAN errors
2 strange PATRAN errors
(OP)
Hi alls,
I have a 2 strange PATRAN errors. I don't know it correlated or not.
1)
When try to Export bdf from a defined Job, my PATRAN Crash again and again, generating just and empty bdf with 0KB size.
Actually my PATRAN db is > 1GB therefore I may immagine is a Kind of size Problem. Note this only happens with 1 Job, all the rest works perfectly.
2)
Trying to clean the db, I tried to delete unused LCs from "Load Case" tab. For some of them I obtain the error:
"
The selected loadcase is associated with <MSC.Nastran> analysis step <XXX>. Loadcase is not deleted
"
I already deleted the PATRAN Job that was associated to this LC, so it is actually unused (or should be unused) in my .db file, but nevertheless I cannot delete it.
Any idea of what can cause ´These Errors?
Thanks in advance

RE: 2 strange PATRAN errors
Try importing the Patran db into a new Patran db. That is to say, create a new, empty Patran database and use the File, Import option to set the Source: to MSC.Patran DB and select the old database. This might get round the export issue.
For the LBC issue, there must be something else referencing the LBCs.
RE: 2 strange PATRAN errors
This should solve it.
But you will need to re-create your job as you will have deleted every one of them in your database. That's the catch.
Please let me know if you still get this error after doing this.

RE: 2 strange PATRAN errors
@dmapguru: it partially solved the Export issue (now can Export most LCs)
@aerostress82: I even tried to set the Job to sol 105 to reset LC and than delete Job. I still cannot delete LC.
I reset the db
- exported the load fields to csv and reimported in new db
- transfered the Groups via .ses file
- Import geometry and properties from one of the bdf I was able to Export from previous db
- re-created Jobs
Now it works perfecty.
Thanks for the ideas

RE: 2 strange PATRAN errors
I am using patran 2012, I have the same problem (When try to Export bdf from a defined Job, my PATRAN Crash again and again, generating just and empty bdf with 0KB size).
I added the example, is something very basic to test the program.
Someone can help me please
