I'm currently trying to simulate a distributed load on a large device, which also includes many smaller parts (screw, bolts, etc.). To do so, I've used a pressure load and divided the magnitude of the load by the surface area of the rod, highlighted in red, and used that as the magnitude of the pressure.

 

While I was able to get the solver to output a solution when the only conditions present were a compression only support and the pressure on the rods, I added a moment to the solver and now it isn't returning anything. My mesh size is 2 inches, so I'm not sure if the error is due to that or if I'm overlooking something else.

 

 

Any ideas how to fix this?

 

EDIT: Received this error on the version that only had pressure. Does this mean the model size just has to be reduced? I've tried using a larger mesh of 5 inches and that returns an error about not being able to generate a mesh for all of the parts.

Compression only support is frictionless, so if the moment had any component in the plane of the support, there is no solution if there are no other supports.

The corrective action is to add a support or add a surface and use frictional contact.

The message you got is a warning, not an error. It just says you could wait less time for the solution if you had more RAM or SSD storage.

Ideally I'd like to model a surface and use frictional contact. To do this, would I just model a flat surface in the CAD software I used to create the model and then create a frictional contact between that and the bottom faces of the model?

i am trying to simulate a concentrated load on a fixed support beam, my size of meshing is 100mm, whe a i click on solve, the solution status freeze on the half of the mathematical model, i am talking about hours, never showed me up the results.
