Transient cool : Create 3D mold mesh 2 nd path : Mold model fully created in CAD Requirements : Part geometry Mold block(s) with holes for channel and runner system, insert (optional) Curves to mesh the channel and runner system (can use iges) Benefit : Can deal with complex mold with insert and more than 1 mold block Limitation : More manipulation to set different mesh sizes
Transient cool : Mesh requirement Cooling lines Ratio of 2.5 between diameter and beam length is appropriate Can be smaller, solver more tolerant than BEM Mold block or insert versus part mesh Better accuracy if mesh size is similar at interface part/mold. Appropriate ratio is 2 to 4 between part edge length and mold edge length External mold surface versus internal mold surface A ratio of 3 should be a good compromise for mesh quality and number of elements
Transient cool : Create 3D mold mesh Tips for mesh size : Set selection to CAD face(mesh-selection) Setup a global edge length equal to the desired edge length for internal surfaces Select the 6 external faces of the mold and put a larger edge length(ratio of 2 to 3) Use chord angle in CAD tab of the mesher, for nicer mesh around circuit s holes.
외부열전도계수 Applies only on free surface of tetra Faces of tetra not in contact with another tetra Can be use to simulate insulator on mold No differences between mold block and insert for the solver Using different properties is just easier for post processing
