Solid stress in frequency response SOL111

[Nikolay A]

Hi Steve,

many-many thanks for the package!

I encountered the issue when parsing STRESS data for any solid elements in frequency response (SOL111). The example files are attached.

Solver: Simcenter Nastran 2022.1

PyNastran version: 1.5.0+dev.no.checksum.error

Details:

• a small model contains all element types I need for further analysis (CTRIA, CQUAD4, CHEXA, CPYRAM etc).
• I'm running SOL111 in NX Nastran requesting STRESS(PLOT)=ALL with PARAM,POST,-1
• PyNastran (1.5.0+dev from today) crashes when parsing "cpyram_stress"
• When removing CPYRAM, I have op2_results.modal_contribution for 2D elements, but nothing for 3D

Questions:

• How can I get 3D stress output?
• Could you please point me to the example for looping over the stress output in frequency response, e.g. read all SXX at GRID=0 (centroid for SOLIDs) into dictionary {eid: SXX}?

Thank you!

Cheers,

Nikolay

Looks like that form of solid stress/strain is not supported. I need the f06 results to get it right, so STRESS(PLOT,PRINT)=ALL.

Sure. Please find attached the updated zip.
