Reaction force at gridpoint with enforced displacement - NLGEOM Topology Optimization

Hallo,

 

is there a way to get the equivalent of SPC Force response for topology optimization from a non-linear geometry (NLGEOM) subcase?

 

I have a gridpoint where I define an enforced displacement by constraining it with a SPC. I would like to use the reaction force from this subcase in topology optimization (would like to set a maximum allowed reaction force).

 

Thank you for your answers.

    Hi @Schaltza

     

     

    Can you try with .op2 format instead of H3d?

     

    If this did not help, open the .rad file which are available in your working directory with RADIOSS user profile and add REACFX/Y/Z output blocks which writes reaction forces to T01 file

    Hi prakash,

     

    Hope you doing well

    Here i am need reaction force at constrained location but i unable to get the force it showing zero i defined all the parameters. Can you please check the model once for me .

    And please give feedback. Thanks for your time. i have attached the model as shown below.

    Hi Ajay,

     

    I don't see any specific analysis loadtsep is created. 

     

    Please let me know if I am missing something.
