How to model a 6dofs spring-mass system in one two node model?

[flyingcow1999a]

I checked all ANSYS examples for using spring element with two nodes to model the response to loading in one certain direction. I can do that for any of the six DOFs, three translations and three rotations one by one. However, I do not know how to model all six dofs in one model using two nodes. And want to ask for help from this formum.

For example, I want to model the response of a rigid block supported on the ground(condesned to one node) supported by springs with stiffness for six dofs to multiple direction loading - translational forces and bending moments. I can calculate the response in each direction one by one and later combine them together. What I am thinking is to model the springs for six dof in one mode by six dofs. I just cann't figure out how to do that. Any examples I can use for reference?

Anybody can help me? Thanks...

could you possibly use a general joint element?
Like this one?
