As it goes I need to create a simulation fixture. The best example I can use is a wood 2x4 place on a table. Each end is overhanging the table. I apply a force to each end. As one would expect the center of the 2x4 bows off the table. What fixture would I use for simulation. I have choosen on flat face, but Simulation errors out, I think I am not constraining the model enough.
