The mesh should have noFree edgesEdge of an element should not touch any other elementNon-Manifold edgesEdge where 3 or more elements share the edgeA Tintersection
Fusion meshes must be matchedOne side of wall thickness to anotherAt least 85% to prevent warnings in Flow analysisAt least 90% for good warp resultsReciprocal match is when two elements match each otherMust be above 90% for good warpage
Aspect RatioAverage < 3:1Maximum < 6:1 Higher can be tolerated for flow analysis, but causes problems with cool and warpVery high aspect ratio triangles, which have their longest side in the direction of flow, should be avoidedIf very high aspect ratios cannot be avoided, the longest side should, if possible, be at right angles to the flow direction
Thickness has the greatest effect on pressureFlow length has the second greatest effectVolume has no effect on fill pressure assuming thickness and flow length are constant
