Results When Using Automatic Midsurface Connections
When you model an assembly using midsurface compression and the automatic midsurface connections established by this type of modeling connect overlapping surfaces subject to displacement, Creo Simulate can give results that do not reflect the actual displacement.
This figure shows an assembly with two mated parts before you apply any displacement stress.
This figure shows the actual results when the two parts are modeled as solids resulting in no slippage along the common surface.
This figure shows what happens when you use midsurface compression with automatic midsurface connections. Creo Simulate displaces the assembly about four times further than it does for solid parts.
If the difference between the actual displacement and the displacement reported by Creo Simulate is beyond an acceptable tolerance, consider one of these alternatives:
In situations where the difference is unacceptable for the entire model, we suggest that you model your assembly as a solid.
In situations where the difference is only unacceptable for certain mated components, you can create welds, fasteners, or rigid connections to model the behavior in these areas. Alternatively, you can use beams to stiffen the model and, thus, correct the behavior.
