Enables/disables loosely coupled conjugate heat transfer. This increases the robustness of the energy equation calculation, and specifies that multidomain architecture is used within a single Fluent session to enhance the performance of the simulation. For transient simulations, it works in conjunction with the solve/set/transient-controls/solid-time-step-size text command, and thereby enables the use of a user-specified time step size for solid zones that can be larger than that used for the fluid zones. For steady flows, it enables a loose coupling of the fluid and solid zone calculations at a specified number of iterations.

Enters the set menu for loosely coupled conjugate heat transfer.

Enables auto partitioning by zone or by domain.

Sets the auto partition load vector.

Sets the partition method.

Sets auto partition pre-testing optimization.

Uses partitions in a pre-partitioned case file.

Allows partitions to cross zone boundaries (the default). If turned off, it will restrict partitioning to within each cell zone. This is recommended only when cells in different zones require significantly different amounts of computation during the solution phase; for example, if the domain contains both solid and fluid zones.

Disables all optimizations.

Enables all optimizations.

Sets cell function.

Enables / disables dynamic load balancing for discrete phase model cases that use a second domain for DPM particle tracking (that is, cases for which you have enabled the define/models/dpm/parallel/hybrid-2domain? text command).

Uses face area as connection weights.

Sets ISAT weight.

Enables the Laplace smoothing option which can prevent partition boundaries from lying along regions of high aspect ratio cells.

Sets the number of cells desired for each partition. This is useful, for example, when computing on multiple machines with significantly different performance characteristics. If left unset, each partition will contain an approximately equal number of cells. Normalized relative values may be used for the entries.

Toggles the optimizer that attempts to decrease the number of interfaces by eliminating orphan cell clusters.

Enables / disables model-weighted partitioning. This option works with the METIS partitioning method, and specifies that Fluent automatically calculates the weighting based on the cell count and the models and attributes specified as weights (using the parallel/partition/set/isat-weight text command, for example).

Uses number of faces as weights.

Sets the,, and coordinate of the origin used by those partitioning functions that require a radial distance. By default, the origin is set to (0, 0, 0).

Sets DPM particle weight.

Enables the operation that determines the best coordinate-splitting direction.

Uses solid thread weights.

Toggles the optimizer that attempts to minimize the number of interfaces by modifying the partition boundaries to reduce surface area.

Controls the amount of information that is printed out during partitioning. If set to 1 (the default), a text character. is displayed during each bisection, and partition statistics are displayed once the partitioning completes. If set to 2, additional information about the bisection operation is displayed during each bisection. If set to 0, partition statistics and information during each bisection are not displayed.

Sets VOF free surface weight.
