Error 144

Hi,

I have an error with the solver:

*** ERROR # 144 ***
CPYRA element 2195730 has singular strain functions.
Please check material data.

I'm trying to make a buckling simulation of an honeycomb cell and I choose mat 9 ort as card image but if I change to mat 1 I haven't this problem.

Thanks for attention

Antonio

I think the problem is coming from the material.

can you please check the material data?

Why E1 is not provided?

Hi Prakash,

Thanks for you answer. E1 and E3 are not provided because the data sheet provides me only the modulus along 2 direction.

Should I put a symbolic value and try to run?

Yeah, please do so. Maybe E1=E2?
