*TRANSPORT EQUATION SOLVER
Specify the linear solver and parameters for solving the transport equations in an Abaqus/CFD analysis.

This option can be used only as a suboption of the *CFD option to enable the linear solver parameters for solving the transport equations of scalar variables such as temperature, species concentration, turbulent eddy viscosity, turbulent kinetic energy, etc.

Optional parameters:

CONVERGENCE

Set CONVERGENCE=ON to write convergence information to the log file.

Set CONVERGENCE=OFF (default) to suppress convergence information.

DIAGNOSTICS

Set DIAGNOSTICS=ON to write diagnostic information about the solver to the log file.

Set DIAGNOSTICS=OFF (default) to suppress diagnostic information.

TYPE

Set TYPE=DSFGMRES (default) to enable the Diagonally Scaled Flexible Generalized Minimum Residual linear solver.

Set TYPE=DSGMRES to enable the Diagonally Scaled Generalized Minimum Residual linear solver.

Data line to specify the transport equation solver parameters: 

First (and only) line:

  1. Maximum number of iterations (default=50).

  2. Interval to check linear convergence (default=2).

  3. Linear convergence criterion (default=10–5).
