Specify solver settings#
PyFluent supports using Solver TUI commands and Solver settings objects to specify solver settings.
The examples on this page show how you use Solver TUI commands to specify solver settings.
Set steady or transient solution model#
This example shows a comparison between the TUI commands and the Python code for enabling and disabling the steady and unsteady (transient) solution model.
/define/models/steady yes /define/models/unsteady_1st_order yes
import ansys.fluent.core as pyfluent solver = pyfluent.launch_fluent(precision="double", processor_count=2, mode="solver") solver.tui.file.read_case("file.cas.h5") solver.tui.define.models.steady("yes") solver.tui.define.models.unsteady_1st_order("yes")
Set pressure-based or density-based solver#
This example shows a comparison between the TUI commands and the Python code for enabling and disabling the pressure-based and density-based solver models.
/define/models/solver/density-based-explicit yes /define/models/solver/density-based-implicit yes /define/models/solver/pressure-based yes
solver.tui.define.models.solver.density_based_explicit("yes") solver.tui.define.models.solver.density_based_implicit("yes") solver.tui.define.models.solver.pressure_based("yes")
Set gravitational acceleration#
This example shows a comparison between the TUI command and the Python code for setting the gravitational acceleration.
