What’s the Difference Between C3D10 and C3D10HS Elements?

EmailFacebookLinkedInTwitterShare

And When Do You Use One Over the Other? The C3D10 and C3D10HS are both 10 node tetrahedral elements in Abaqus with quadratic interpolation of displacement, otherwise colloquially referred to as “2nd order tets”. While the C3D10 is the standard or “vanilla” 2nd order tet element, C3D10HS is marketed as a 2nd order tet element with improved surface stress visualization. To understand how and why C3D10HS is different from C3D10, we need to quickly review how stress is calculated using […]

Abaqus/Explicit 2019 Now Supports C3D10 Tetrahedral Elements

EmailFacebookLinkedInTwitterShare

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 […]
