SOL600 with Laminate 3

[VanDenStrom]

Hi,

I need to help with a task with laminate(PCOMPG), which is solved using SOL600. Preprocessing and solving are without problems. But I don't understand a postprocessing in this case. I need to get results for laminates (stresses in layers, fail criterion...).

I have 2 options:

1. use MARCOUT and EXXX numbers for getting requested results (which numbers?)

2. use OUTR=OP2 - but it doesn't work with laminate in my case. (When I swap PCOMPG for PSHELL, it does work)

Am I right? Should I add some other PARAMETERS? Please, help me with this problem.

Sorry for my bad english,

Thank you,
VanDerStrom

The last that I checked, SOL600 was not capable of supporting PCOMPG's but only the standard PCOMP's

Your option would be to convert all your PCOMPG's to PCOMP's and use

$
SOL 600,106 outr=op2,f06
cend
$

Give it a try !

I tried it but still doesn't work.

I forgot to say there is BCONTACT too. Could it be a problematic combination with laminate (PCOMP)? Should I add other paramater(s) to solve it?

I tried using a small test problem with PCOMP's, and what I find is that in-spite of specifying outr=op2,f06, SOL600 only creates a *.t16 file

Post processing the *t16 file only yeilds standard stress o/p quantities.

I suggest you take this up with your local MSC technical representative, unless somebody else on this forum can share their experiences.

Hi,
I contacted technical support in MSC. After 3 weeks they told me in Nastran 2012 is a bug - in t16op2 translator. Can't translate .t16 to .OP2 with laminate (PCOMPG/PCOMP). With PSHELL is no problem. So they started to repair this bug in new version of Nastran, I think, it will take at least 1 or 2 years.

If someone of you has experience with this problem, share it with us.

Bye

Thanks for the update.

I'll definitely give you a star for sharing this one with the group.
