The following types of external conditions can be prescribed in an
Abaqus
model:
- Initial conditions
-
Nonzero initial conditions can be defined for many variables, as described
in
Initial conditions in Abaqus/Standard and Abaqus/Explicit.
- Boundary
conditions
-
Boundary conditions are used to prescribe values of basic solution
variables: displacements and rotations in stress/displacement analysis,
temperature in heat transfer or coupled thermal-stress analysis, electrical
potential in coupled thermal-electrical analysis, pore pressure in soils
analysis, acoustic pressure in acoustic analysis, etc. Boundary conditions can
be defined as described in
Boundary conditions in Abaqus/Standard and Abaqus/Explicit.
- Loads
-
Many types of loading are available, depending on the analysis procedure.
About loads
gives an overview of loading in
Abaqus.
Load types specific to one analysis procedure are described in the appropriate
procedure section in
Analysis Procedures.
General loads, which can be applied in multiple analysis types, are described
in:
- Prescribed
assembly loads
-
Pre-tension sections can be defined in
Abaqus/Standard to
prescribe assembly loads in bolts or any other type of fastener. Pre-tension
sections are described in
Prescribed Assembly Loads.
- Connector loads and
motions
-
Connector elements can be used to define complex mechanical connections
between parts, including actuation with prescribed loads or motions. Connector
elements are described in
About connectors.
- Predefined
fields
-
Predefined fields are time-dependent, non-solution-dependent fields that
exist over the spatial domain of the model. Temperature is the most commonly
defined field. Predefined fields are described in
Predefined Fields.
