Parting PlaneOptionalUsed to define a resistance of heat transfer between two pieces of mold material of the same typeMold BoundaryRecommended, but optionalDefines the outer boundary of mold and space that heat transfer calculations are doneIn-mold labelOptionalDefines metal or polymer thin film that the part fills over, such as a printed film
Cooling errors caused byHigh aspect ratiosVery short beam elements (cooling channels and runners)Beams overlapping trianglesErrors that can occurElements too closeOverlapping elementsErrors can be caused by elements in plane or out of planeModeling and meshing errors can causeConvergence problemsNon-logical temperature distributions (e.g. hot spots)
Can get ??too close?? warnings with elements in plane or out of planeCaused by long average element length and close centroid distancesCooling very sensitive to aspect ratio Must be 6:1 or less to prevent significant aspect ratio problems
