    hello,

    after I created the temp nodes and apply the forces and run the optiStruct, I received this error

     

    ERROR 2148

    Invalid design problem

    All the sensitivities of response 1 objective are zero

     

    How can I resolve this problem?

     

    thank you

    Hello,

     

    Are you doing Optimization in OptiStruct?

    If so please check your responses and objectives as there is some problem in them.

     

    Thankyou

    temp node must connect to structure (element), use RBE2 or RBE3, ... to connect it
