Abaqus/Explicit has long required second-order tetrahedral elements to be of the C3D10M (the ‘M’ stands for modified) element type. This has now changed — true second-order C3D10 elements are available!
C3D10 elements in Abaqus/Explicit:
- Are true quadratic elements (“modified” elements are a special case of “numerical composite”)
- Are higher accuracy than their first-order, linear (C3D4) counterparts
- Are higher accuracy than their “modified” (C3D10M) counterparts
- Are recommended over C3D10M by Dassault Systèmes
- Have a bigger stable time increment than C3D10M
- Are computationally less expensive than C3D10M
- Support all the same loadings, material behaviors, and boundary conditions as do the existing solid continuum elements (C3D8R, C3D10M, C3D6, etc.)
- Are also supported in STD-to-XPL and XPL-to-XPL import
- Are not supported with selective subcycling
