Curing Contact Setup

Define the frictional contact between the composite (P8-1) and the mold (TOOL-1). This is the physical mechanism that constrains the composite during curing and creates asymmetric springback upon demolding.

When to Invoke

• User asks to set up contact between composite and mold
• User mentions "接触", "摩擦", "模具接触", "contact pair"
• User needs to change friction coefficients
• User encounters contact-related convergence issues

Contact Pair Definition

*Surface, type=ELEMENT, name=com-surface
P8-1.S1                      # Composite outer surface (contact with mold)

*Surface, type=ELEMENT, name=tool-surface
TOOL-1.S4, S6                # Mold contact surfaces
