ERROR # 1578 ***
Altair EmployeeHi,
I want to do Non Linear Material analysis of Plastic component. I have defined Stress - strain curve in TABLES1 card and assigned it in MAT1 with MATS1 card. Analysis is of NLSTAT type. I am getting below Warning & Errors.
*** WARNING # 3003
The Young's modulus calculated from the TABLES1 bulk data entry ID=10
is not equal to the value specified in the corresponding MAT1
(11475.000000 != 10800.000000). This will produce
inconsistant elastic and plastic deformations and may yield unexpected
results.
*** ERROR # 1578 ***
for material id = 2 referenced from property id = 4.
MATS1 is presently not supported for membrane elements (referring to
PSHELL with only MID1 present).
Thanks & Regards,
Suraj

Large strain for shells in LGDISP is currently not available with Optistruct.It must be available in future HW solver Patches.Will update you once it is available.

Hi Suraj,
Are you trying to solve a pure membrane problem?
Plasticity for pure membrane is not implemented, please activate MID2 in PSHELL property and try again.

hi Suraj,
Uncheck the MID2 entry in your SHELL as shown in the image below:
