Superelement Model

When I run the model,

there is this warning:

 

'Input deck contains 1 K2PP/M2PP/B2PP DMIG arrays but there aren't
 any SUBCASEs of suitable type. These DMIG arrays are eliminated'

Could you explain me if the supelement model is working well?

 

Regards

    Hi,

     

    Do you have any direct input stiffness matrix or mass matrix in your model?

     

    If yes, these martices are used only in dynamic response subcases (except normal modes). 

     

    Kindly check and update the model.

    It seems OS is ignoring B2PP and K2PP, because “there are no suitable type subcase”

    I think that K2PP is currently supported only for complex eigenvalue analysis in OS. B2PP is not supported.
