Could not transfer loads and constraints to the solver

Hi experts,

I am using ANSYS 19.2. I want to impact two elements. And I want to add a point mass on moving element in the simulation. My simulation was OK without a point mass. But my simulation does not work with a point mass.

At the beginning it shows me an error "Deformable behavior for remote entities is not supported in Explicit Dynamics systems. Please change such behavior to Rigid". And I changed the behavior of the point mass to rigid. Now I got an error "Could not transfer loads and constraints to the solver".

This is the solver output:

    Hello @nuwan,

    When you set the deformation behavior as rigid, all the surfaces that are scoped to the point mass become rigid in a sense. So if you have any boundary conditions/loads that are scoped to these surfaces (to which point mass is attached) it might create problems. Could ensure that this doesn't happen in your case. Also, provide an image of your boundary conditions, loads and surfaces to which remote point is scoped.

    Regards,

    Ishan.
