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 require in a number of locations. When the overall element size is reduced to 3″, it takes 1002 seconds to mesh.

Sphere meshed at 5in element size.

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.

Sphere split into 12 bodies.

The sphere split into 12 bodies

The mesh times go down significantly as the sphere is split into smaller bodies.

5 inch mesh size for split sphere

6 body sphere at 5 inch mesh – mesh time is 46 seconds (127,000 nodes, 63,000 elements)

Detail of the 12 body sphere at 3 inch mesh size.

12 body sphere at 3 inch mesh – mesh time is 161 seconds (326,000 nodes, 163,000 elements)

Mesh Time for all runs

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 as the number of elements exceeds 1 million…
