Sir, how can I model  a component in Radioss so that it would be rigid for some time of calculation and then deformable or vice versa like deformable to rigid  as in lsdyna?

    Hi Ramkiran,

    You can use /RBODY ON and OFF options in the engine file to activate or deactivate rigid bodies.

    The format is :
    /RBODY/Keyword

    node_ID1...  node_IDN       Where Keyword is ON or OFF and list of master node numbers of rigid bodies are provided.

    Based on the need you can activate and deactivate the rigid body using this option for the required time and multiple engine files has to be created.
