Fixing the MeshFixing the Mesh

Run Auto fix firstResolve any remaining overlappingRun Global Merge nodes– Adjust merge tolerance value as required– To improve aspect ratios

Manually merge nodes to fix remaining AR problems


When to Quit?When to Quit?

Number of high AR elements must be below limit flow solver requirementsCooling and Warpage more sensitive to AR than Flow– If going past flow, get a better model, to desired

limits <6:1
