Abaqus element indexes and naming conventions are the product-specific lookup system for mapping element type names to families, topology, formulation, integration, and manual sections.
How It Works
An Abaqus element name usually begins with a family prefix and includes dimensionality or topology information. Examples include C for continuum, S for shell, B for beam, T for truss, COH for cohesive, CONN for connector, AC for acoustic, EC for Eulerian, PD for discrete particle, and PC for continuum particle.
Suffixes and trailing letters often identify formulation variants. R commonly marks reduced integration, H marks hybrid pressure treatment, I marks incompatible modes, and field letters such as T, P, or E identify coupled temperature, pore-pressure, or piezoelectric variants in many continuum families.
Volume IV includes separate indexes for Abaqus/Standard, Abaqus/Explicit, and Abaqus/CFD. Some internal element names may appear in output databases or data files even though they are not listed for user selection.
Why It Matters
The element index is the fastest way to prevent a modeling mismatch. It confirms whether the intended topology, physics, formulation, and product are actually available before the analyst commits to a mesh and procedure.
