    Ahilan,


     


    Do you want to create rigid wall/component for OptiStruct?


     


    You can use RWALL in OptiStruct to model Rigid walls for NLGEOM analysis.


     


    Go to Analysis>> Rigid walls to create rigid walls.


     


    The shapes of these walls are limited. Available shapes are Infinite plane, Sphere, cylinder, parallelogram.

    Actually i ll solve in abaqus and mesh in HM.

     

    In the assembly i analyse, there are two different components; one is of very high stiffness compared to other. so i want to define that component as rigid. In abaqus while creating a component we can define as rigid. but my component is of complex shape so i mesh in HV. Once i take to abaqus i cant define as rigid for the component imported from HM. So i want to define the component as rigid in HM itself or any other trick?

    Hi Ram,

    Which solver are you talking about?

    If it is RADIOSS there are pre defined rigid walls available and mesh is not required.
