export nastran/patran files ? 1

[rb1957]

is there a way to export nastran/patran files ?

i tried the neutral file, but appraantly this doesn't read properly.

looked for .bdf, the closest i could see was echo the input file (into the f06).

?

File > Export > Analysis Model
This will geenrate blk, dat, bdf files, which are ANSI bulk files.

In "Other Interfaces" there also is a "Patran" option. I'm not a PATRAN user, I'll leave it to you to test if that works

that's the way i went, but the options don't include .bdf
i can get some PATRAN options ... but doesn't translate RBE spider elements.
i'm using 11.0.0.

I looked into it not long ago, using the NEiNastran version of Femap 11 and never got it to work. NEi told me there was an OP2 translator that I could purchase. I never pursued that option since the customer wanted me just to use Patran/Nastran.

The best way to transfer data from Femap to Patran is the Nastran bulk data file. You should use Export/Analysis model. This will write a .bdf file and include all of the FEM data but will not include any geometry/groups or other data. File extensions .bdf and .dat are the same Nastran bulk data format. So in Patran you would choose to import a nastran bulk data file.

This is from the Femap documentation:
8.8 Patran Interfaces

There are three direct interfaces between FEMAP and MSC.Patran. You can write a FEMAP model to the MSC.Patran format for analysis, read an existing MSC.Patran model, or read analysis results for post-processing. The model interfaces use the MSC.Patran neutral file format. As you can see from the table in "Analysis Software Interfaces", they only support the finite element entities in FEMAP. You cannot transfer geometry (points, curves, surfaces, or volumes) between FEMAP and MSC.Patran using these interfaces.

thx ... i was distracted by the "other" button which doesn't lead to NASTRAN. thx, have it now.
