Hi,
I am trying to do the second phase of the composite optimisation process - the sizing part.
However, I get the following error : 'invalid design parameters for w.r.t'
I realise that if I change my laminate properties from 'Smear' to 'Total' it works. However, I am not sure if this is correct.
Also, if I add a buckling load, neither of these work.
Can you help me? it is urgent.
I have attached the FEM file with the issue
Best Regards,
