Hi All,
I'm having the following simulation error.
FFEPlus solver failed for constraint equations;
Solidworks Simulation is to switch the solver to Intel Direct Sparse.
My intent with the simulation is to determine the stress generated in the angled bracket whilst restraining two perpendicular concrete lintels (which themselves are supported on brickwork). If anyone could help me with this it would be much appreciated.
I was wrong about the loose plate. It rotates wildly. I'd leave it off at first as it's just a shim to the anchor block, which can be a smaller body or even virtual wall for a starting analysis.
The forces are extreme and displacements (note 1e-6 scale here) follow. Pressure of 1520 N/mm^2 times 307495 mm^2 gives 47 million Newtons.
As for general simulation advice: start simple and build up to realistic contact analysis.
Hi,
Thank you for the help.
I was able to get the model working in the end after following your advise and changing the loads (got the units wrong).
I changed all the contact sets to surface-surface ("High accuracy") and switched to the direct sparse solver.The bolt setup did not make physical sense so I changed it to a threaded screw. The middle plate of the bolt grip remains loose (free to slide), but with a direct solver I don't expect it to fly away.
Running now.
This is exactly the kind of problem covered in the newly published Solidworks Simulation for Real Machines. A lot of points that are never touched in Solidworks documentation and problems beyond the practical scope of any Solidworks class are covered.
