Reduce Your Mesh Time

Inside view of a storage sphere.
Front view of the storage sphere.
This 25ft diameter storage sphere with unusual legs is solid meshed. At a 5″ element size (the element size that will mesh), it takes 172 seconds to mesh. The bad news is that a smaller mesh is required in a number of locations. When the overall element size is reduced to 3″, it takes 1002 seconds to mesh.
Front view – Nodes = 123,000, Elements = 61,000, 172 seconds to mesh
Detail meshed at 3″ size – Nodes = 318,000, Elements = 158,000, 1002 seconds to mesh
Splitting large objects into smaller items can reduce the mesh time. Here the sphere is split into 6 and 12 pieces.
The sphere split into 6 bodies
The sphere split into 12 bodies
The mesh times go down significantly as the sphere is split into smaller bodies.
6 body sphere at 5 inch mesh – mesh time is 46 seconds (127,000 nodes, 63,000 elements)
12 body sphere at 3 inch mesh – mesh time is 161 seconds (326,000 nodes, 163,000 elements)
Summary of all mesh time data. The reduced body size makes a huge difference as the number of elements increases.
Reducing the body sizes can have a huge impact when the number of elements exceeds 1 million…
