This is one of the most frequently asked questions in SOLIDWORKS Simulation:
Is there any better choice for Global Contact in SOLIDWORKS Simulation?
There are three different types of Global Contact in SOLIDWORKS Simulation as shown in the figure below:
- No Penetration,
- Bonded and
- Allow Penetration
In general, you should avoid using No Penetration as Global Contact; since SOLIDWORKS Simulation is constantly looking to check if No Penetration contact condition is met between all components in the model. This can take a considerable amount of memory resources especially for large assemblies.
Accordingly, it is better to keep Global Contact as Bonded or Allow Penetration and use local No Penetration contact.
