SOL103 with MATORT

Hello,

Is it possible to run SOL103 when your model contains PSOLIDS with MATORT? I tried running such a problem and while no errors occured in the f06 file, the results where definately wrong (eigenfrequences were too low).

The header I used was the followng

SOL103

CEND

DISP(PLOT) = ALL

METHOD = 1

BEGIN BULK

PARAM,POST,-1

PARAM,INREL,-2

PARAM,GRDPNT,0

*METHOD = EIGRL with ND = 20

Is it possible that I made a mistake in the header?

Thanks

Josef

Hello,

Thanks, this was very helpful. However, no matter what I do, the orientation for PCOMPLS is not set properly. That's why I was using PSOLID. When I have already created solid elements, setting their orientation from Nastran -> Utilities -> Material Orientation doesnt make for an orthotropic element.

Is there another way to define the composite solids orientation?

Thanks,

Josef

You can try Utilities-> Properties-> align solid elements

There are many options over here.

Another way is to directly create a Coordinate system and call it in the Properties as shown below.

Thank you, turns out it was a matter of the elements I was using. The orientation was ruined because of me using tetras instead of hexas. Once I switched to hexas, the orientation was fine.
