Specifies which type of tetrahedral element to use for the core elements in the stress analysis of the core.
The following options are available:
- 4-noded tetrahedra (fastest)
This is the type of tetrahedra that are created when the core is meshed in this product. 4-noded tetrahedra require less memory (by a factor of five) and require less computation time (by a factor of 10) than 10-noded tetrahedra, however the solution is less accurate. Select this option if the core has been meshed with at least four elements across the thickness.
- 10-noded tetrahedra (most accurate)
If you select this option, the 4-noded tetrahedra created in this product will be upgraded to 10-noded tetrahedra by the addition of an extra node on each tetrahedron edge. The solution with 10-noded tetrahedra is more accurate than 4-noded tetrahedra, however, the memory and computation times are considerably higher. Always select this option if the core has been meshed with only one or two elements across the thickness.
