Abaqus Co-Simulation Models Reference

The Abaqus co-simulation model allows you to couple Simcenter STAR-CCM+ and Abaqus in a co-simulation analysis. This type of co-simulation supports implicit or explicit coupling.


Model Names	Abaqus Explicit Coupling		Simulations exchange data once per time-step.
	Abaqus Implicit Coupling		Simulations exchange data more than once per time-step.

Boundary Settings

Available for boundaries of type Wall.

External Code Coupling Specification: Allows you to assign the boundary to a co-simulation zone for coupling. During the co-simulation, the Simcenter STAR-CCM+ boundary exchanges data with the corresponding coupled surface in the partner simulation, according to the co-simulation zone specifications.

Abaqus Co-Simulation Solver Properties

Verbosity: Allows you to choose how much information Simcenter STAR-CCM+ reports in the Output window while the simulation is running. This property is useful for debugging problems when they occur. The available options are None, Low, and High.
Solver Frozen: When On, the solver does not update any quantity during an iteration. It is Off by default. This is a debugging option that can result in non-recoverable errors and wrong solutions due to missing storage. See Finite Volume Solvers Reference for details.
Temporary Storage Retained: When On, Simcenter STAR-CCM+ retains additional field data that the solver generates during an iteration. The particular data retained depends on the solver, and becomes available as field functions during subsequent iterations. Off by default.

Field Functions

Incremental Nodal Displacement: Represents the increment of the imported Abaqus displacement over a time-step, that is, the difference between the displacement imported from Abaqus at the current time-step, and the displacement imported from Abaqus during the previous time-step.; You can visualize the Incremental Nodal Displacement on the Simcenter STAR-CCM+ fluid region, or part, that is coupled with Abaqus.
Co-Simulation Exchange: Represents the number of exchanges between Simcenter STAR-CCM+ and Abaqus.
Co-Simulation Map Face Error: Indicates error when mapping field data onto faces.
Co-Simulation Map Vertex Error: Indicates error when mapping field data onto vertices.
