Hi,
Use Masses in 1D panel to create point mass.
You will also have to connect the mass element to the body using rigid elements
Hi Rahul,
I am finding the forum really helpful. I used RBE3 to connect the point masses to the structural members, and assigned values using CONM2. How do I separate the non-design components - which in my case are the mounting points? How do I exclude them from the optimization process? Do I have to create spider rigids in bolt locations?
Thanks,
Ginobili
to define a Non-Design Space for optimization, you need to create a separate component and property. It is necessary to either separate the areas on a geometry level (i.e. before meshing) or on the element level (after meshing).
After meshing, you still can move areas to the Non-Design component. Please use the 'organize' function within HyperMesh.
The following movie shows all necessary steps on a simple part:

I have created the point mass and attached it to the component by RBE3 element. I have 2 questions,
1) Which property I should assign for the RBE3 component??
2) which material I should assign to the RBE3 component??
RBE 3 elements do not require any material and properties as they are working as interpolation elements. You can run without assigning anything to it

RBE3 and RBE2 don't need element or property. If you are using mass with any beam or rod elements, they require property and material
