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,

    -Eric
