Is My SOLIDWORKS Model Constrained Properly?

EmailFacebookLinkedInTwitterShare

One problem many face when running simulations is how to add fixtures and/or which fixtures properly constrain their model.  In some cases the answer is easily evident.  In the case of a hook attached to a wall, there should be a fixed geometry on the back.  In the case of a nail, the same fixture should be used, as shown below. Unfortunately most simulations, if not all are not that simple.  While much of knowing which fixture is best comes […]

Unstable Models in SOLIDWORKS Simulation

If you use SOLIDWORKS Simulation for an extended period, you’ll soon see that it has some strange error messages. This is one of my personal favorites: The Iterative Solver stopped, so what does this mean?  Thankfully the SOLIDWORKS Knowledge Base has (nearly) every Simulation error message documented so it’s an easy search to learn that it represents rigid body modes because of missing boundary conditions. Rigid Body Modes What are rigid body modes?  It means that a body is not […]
