Curing Boundary Conditions

This skill defines all boundary conditions for the P8_mold curing model, including the critical distinction between mold-constrained (correct) and ENCASTRE-constrained (incorrect) approaches.

When to Invoke

• User asks to set up boundary conditions for a curing model
• User mentions "约束", "边界条件", "固支", "模具约束"
• User needs to define Set-2 for springback
• User encounters constraint-related issues (e.g., symmetric deformation)

Critical: Two Constraint Paradigms

Correct: Mold Contact Constraint (P8_mold)

The mold (TOOL-1) is fixed in space, and the composite is held only by friction contact with the mold. This allows the composite to slide and expand during curing, which is the real physical mechanism.
