.f06 file big size issue [MSC NASTRAN] (how to split) 1

[Abi786]

Dear All

Greetings

How to manage / split output file .f06 into multiple to reduce its huge size because of large structures problems and non-linear solutions?
[Most available text-editor are not able to open such big files, that's why need to customize the output to reduce file size]

Advance thanks for your help

Regards,
Abi

I use (and love) UltraEdit for this purpose. Not free, but fairly inexpensive. Free trial for 30 days is available. I like the Nastran syntax highlighting.

Hi Abi, could you find out why your .f06 file is too large?
If you are unable to open and read, then better to run just a small part of your FEM just to check.
Try to focus on lines which have a lot of repetitions.
Example: if you have solid element (CTETRA10, HEXA8 etc.) then you may recieve message in .f06 that DOP in rotations are not defined, it look like this:

G R I D P O I N T S I N G U L A R I T Y T A B L E
0 POINT TYPE FAILED STIFFNESS OLD USET NEW USET
ID DIRECTION RATIO EXCLUSIVE UNION EXCLUSIVE UNION
729192 G 6 0.00E+00 BF F SB S *
729193 G 4 0.00E+00 BF F SB S *
729193 G 5 0.00E+00 BF F SB S *
729193 G 6 0.00E+00 BF F SB S *
729194 G 4 0.00E+00 BF F SB S *
729194 G 5 0.00E+00 BF F SB S *

etc.

This you can simply suppress by adding of parameter:
PARAM, PRGPST, NO

There many options how to reduce .f06, but it is better to know what...

Hope this helps, Jan
