Hello,

I'm new to solidworks plastics. I need to simulate a mold with two different cavities.

I made a part with 11 bodies and I assigned each body to a domain.

• 2 cavities
• 4 cooling channels
• 2 mold bodies
• 2 sprues (runner)
• 1 runner

After assigning the element sizes I press the next button and I get the following error:

"More than one isolated cavity detected, which is not supported. Please connect the cavities with a runner system."

The two cavities are connected with via 3 runner bodies (2 sprues and one runner). I get the same error even if I combine the runner bodies into a single body.

All of the bodies have been checked for interference.

The points that the sprues connect to the cavities (gates) make contact with both bodies.
