Hi,

I am designing a wheelchair frame, and am trying to do some analysis on the frame. I am relatively new to solidworks simulation, and having problems doing it.

I am trying to simulate a force being exerted downwards on the cross members circled.

When i try to run the simulation it says the meshing failed.

The tubing is hollow 25mm diameter aluminium, wall thickness 4 mm.

Any help or advice is greatly appreciated!
