udfGetElmRafData()
Return element running average field data at the quadrature point.
Syntax
data = udfGetElmRafData( udfHd, dataName ) ;
Type
User Defined Element
Parameters
- udfHd
- The opaque handle (pointer) which was passed to the user function.
- dataName (integer)
- Symbolic name of the requested data.
- UDF_ELM_VELOCITY
- Velocity.
- UDF_ELM_ACCELERATION
- Acceleration.
- UDF_ELM_PRESSURE
- Pressure.
- UDF_ELM_TEMPERATURE
- Temperature.
- UDF_ELM_SPECIES
- Species.
- UDF_ELM_EDDY_VISCOSITY
- Turbulence eddy viscosity.
- UDF_ELM_KINETIC_ENERGY
- Turbulence kinetic energy.
- UDF_ELM_EDDY_FREQUENCY
- Turbulence eddy frequency.
- UDF_ELM_GRAD_VELOCITY
- Gradient of velocity.
- UDF_ELM_GRAD_PRESSURE
- Gradient of pressure.
- UDF_ELM_GRAD_TEMPERATURE
- Gradient of temperature.
- UDF_ELM_GRAD_SPECIES
- Gradient of species.
- UDF_ELM_MESH_DISPLACEMENT
- Mesh displacement.
- UDF_ELM_MESH_VELOCITY
- Mesh velocity.
- UDF_ELM_MESH_GRAD_DISPLACEMENT
- Gradient of mesh displacement.
- UDF_ELM_MESH_GRAD_VELOCITY
- Gradient of mesh velocity.
- UDF_ELM_TURBULENCE_Y
- Distance to nearest turbulence wall.
- UDF_ELM_TURBULENCE_YPLUS
- Turbulence y+ based on distance to nearest turbulence wall and shear at that wall.
- UDF_ELM_VISCOELASTIC
- Viscoelastic.
Return Value
- data (Real*)
- Pointer to one, two, or three dimensional real array of the requested data. The dimensions of
the array depend on dataName as follows. If the third
(slowest) dimension of the array is equal to one, then the array may be
treated as two dimensional. If the second dimension is likewise one, then
the array is one dimensional. The x, y, z components of the gradient for
gradient quantities are always contained in the last nontrivial dimension.

Description
This routine returns the requested solution data. It is used exactly the same way as udfGetElmData, but returns the running average field versions of the data.
Errors
- This routine expects a valid udfHd.
- This routine may only be called within a Body Force, Material Model or Component Model user function.
- dataName must be one of the values given above.
- The problem must contain the equation associated with the requested data.
- running_average must be turned on in the EQUATION command.
