+# Abaqus Loads and Predefined Fields
+
+## Definition
+
+Abaqus loads and predefined fields are prescribed external actions and non-solution-dependent spatial fields applied to an analysis model.
+
+## How They Work
+
+The load library includes concentrated loads, distributed loads, thermal loads, electromagnetic loads, acoustic and shock loads, pore-fluid flow, substructure loads, added mass, base motion, current density, electric charge, film conditions, fluxes, pressure, and other procedure-dependent loading types.
+
+Predefined fields supply spatially and temporally varying quantities that are not solved as primary unknowns in the current procedure. Temperature is the most common predefined field, especially for sequential thermal-stress workflows.
+
+Prescribed assembly loads include pretension sections for bolts or other fasteners in Abaqus/Standard. Connector elements can also receive prescribed loads or motions to represent actuated mechanisms.
+
+## Why It Matters
+
+Loads and fields are the right-hand side and environment of the finite element problem. They must be compatible with the active procedure, degrees of freedom, element families, and intended time history.

+## Connections
+
+- [[Finite Element Load Vector Assembly]] gives the finite element interpretation of concentrated and distributed loading.
+- [[Abaqus Surface and Assembly Modeling]] supplies surfaces, assemblies, and pretension-related regions.
+- [[Abaqus Multiphysics Coupling and Co-simulation]] uses predefined fields for sequentially coupled analyses.
+- [[Abaqus Connector Elements and Behaviors]] covers connector loads and motions.
