Enter the barycentric interpolation menu.

Classes:

enable_transient_variable_interpolation(...)

Enable transient variable interpolation.

interpolate_flow_cp(service, version, mode, path)

Enables/disables the barycentric interpolation of specific heat to the particle position.

interpolate_flow_density(service, version, ...)

Enables/disables the barycentric interpolation of the flow density.

interpolate_flow_solution_gradients(service, ...)

When enabled, flow solution gradients are interpolated to the particle position.

interpolate_flow_viscosity(service, version, ...)

Enables/disables the barycentric interpolation of flow viscosity to the particle position.

interpolate_temperature(service, version, ...)

Enables/disables the barycentric interpolation of temperature to the particle position.

interpolate_wallfilm_properties(service, ...)

When enabled, the wall film properties (film height, film mass, and wall shear) are interpolated to the particle position.

nodal_reconstruction_frequency(service, ...)

Update nodal reconstruction every N'th DPM iteration.

precompute_pdf_species(service, version, ...)

When this option is enabled for premixed or non-premixed combustion simulations, the species composition in each cell is precomputed prior to tracking particles.

user_interpolation_function(service, ...)

.

zero_nodal_velocity_on_walls(service, ...)

When enabled, sets the velocity at wall nodes to zero.
class enable_transient_variable_interpolation(service, version, mode, path)#

Bases: TUIMethod

Enable transient variable interpolation.

class interpolate_flow_cp(service, version, mode, path)#

Bases: TUIMethod

Enables/disables the barycentric interpolation of specific heat to the particle position. This option is recommended when the specific heat varies with position to avoid discontinuities in the interpolated variable at cell boundaries. For flows with constant specific heat, this option is unnecessary.

class interpolate_flow_density(service, version, mode, path)#

Bases: TUIMethod

Enables/disables the barycentric interpolation of the flow density. This option is recommended when the density varies with position to avoid discontinuities in the interpolated variable at cell boundaries. For constant density flows, this option is unnecessary.

class interpolate_flow_solution_gradients(service, version, mode, path)#

Bases: TUIMethod

When enabled, flow solution gradients are interpolated to the particle position. This can be useful when using physical models that depend on these gradients (for example, the thermophoretic force, pressure-gradient force, or virtual mass force). Interpolating the gradients also improves the accuracy and robustness of the trapezoidal numerics scheme, which is the default method for pathlines.

class interpolate_flow_viscosity(service, version, mode, path)#

Bases: TUIMethod

Enables/disables the barycentric interpolation of flow viscosity to the particle position. This option is recommended when the flow viscosity varies with position to avoid discontinuities in the interpolated variable at cell boundaries. For flows with constant viscosity, this option is unnecessary.

class interpolate_temperature(service, version, mode, path)#

Bases: TUIMethod

Enables/disables the barycentric interpolation of temperature to the particle position. The cell temperature is used by default in calculations of heat transfer to/from the particle.

class interpolate_wallfilm_properties(service, version, mode, path)#

Bases: TUIMethod

When enabled, the wall film properties (film height, film mass, and wall shear) are interpolated to the particle position.

class nodal_reconstruction_frequency(service, version, mode, path)#

Bases: TUIMethod

Update nodal reconstruction every N’th DPM iteration.

class precompute_pdf_species(service, version, mode, path)#

Bases: TUIMethod

When this option is enabled for premixed or non-premixed combustion simulations, the species composition in each cell is precomputed prior to tracking particles. This approach may improve performance for cases with many particles and relatively few cells. By default, this option is set to no, and ANSYS Fluent calculates the species composition during particle tracking. The solution results will be identical for both methods.

class user_interpolation_function(service, version, mode, path)#

Bases: TUIMethod

.

class zero_nodal_velocity_on_walls(service, version, mode, path)#

Bases: TUIMethod

When enabled, sets the velocity at wall nodes to zero. (By default, the nodal velocities on walls are first reconstructed from cell and face values and then corrected to ensure that there are no velocity components directed towards the walls). This may be useful if you want to consider particle impingement on the walls. Note that enabling this option will more likely produce incomplete particles as some particles may settle on the walls.
