no xdb file generated

[victorell55]

Hi,I am new in this forums and I am learning Patran. When I analyse the full model, it doesn't generate a .xdb file.
I found file .f06 empty, so I don't know if there is a problem or not. There is no warning or fatal message in there.
Does anyone have an idea.

I upload my bdf file.

I'm assuming you tried running this job from within the Patran application. If you did this, did you see any error messages in Patran when you ran it? Did any files get generated in the same folder as the Patran database you're working with (like, .f04, .log, etc.)? Finally, can you confirm that you have the Nastran solver installed on your machine?

well...

This sounds like an improper installation issue with nastran. What do your *.log files say after the run??

And also, how are you running nastran? in a stand alone mode meaning generating the bdf from Patran and separately firing a nastran run? or are you invoking nastran from within Patran??

BTW...

I ran your model and it FATAL's out as the constrains that you have specified are inadequate to suppress all 6 rigid-body modes. You have to constrain the R1 d.o.f as you have specified pinned(Tx=Ty=Tz=0) constrains on two nodes along a straight line!
