Hello,

is it possible to get the local Stiffness Matrix of each element?

I need this matrix in an optimization step.

Thank you

Alex

I see some posts about output k matrix of full model only

Can you calculate element k matrix from it shape and properties?

Hello,

I want to avoid that.

But if there is no other way I could do this.

Hello,

I would like to extract the local stiffness elements as well to compare my FE implementation to Optistructs. Is there a method to do this?

Thanks,
