averaging:elemental to nodal (field)
Version: 0.0.0
Description
Transforms an Elemental field to a Nodal field. The result is computed on a given node's scoping.
-
For a finite element mesh, the value on a node is the average of the values of the neighbour elements.
-
For a volume finite volume mesh, the agorithm is :
- For each node, compute interpolation weights for the cells connected to it based on the Frink's Laplacian method.
- If the determinant of the I matrix is zero, switch to an inverse distance weighted average.
- If not, compute the Frink weights and apply the Holmes' weight clip.
- If the clipping produces a large overshoot, inverse volume weighted average is used..
-
For a face finite volume mesh inverse distance weighted average is used.
Inputs
| Input | Name | Expected type(s) | Description |
|---|---|---|---|
| Pin 0 Required | field | field, fields_container | field or fields container with only one field is expected |
| Pin 1 | mesh_scoping | scoping | |
| Pin 2 | force_averaging | int32 | Averaging on nodes is used if this pin is set to 1 (default is 1 for integrated results and 0 for discrete ones). |
| Pin 200 | algorithm | int32 | Forces the usage of algorithm 1, 2 or 3 (default is chosen based on the type of mesh). |
Outputs
| Output | Name | Expected type(s) | Description |

Configurations
| Name | Expected type(s) | Default value | Description |
|---|---|---|---|
| mutex | bool | false | If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads. |
| run_in_parallel | bool | true | Loops are allowed to run in parallel if the value of this config is set to true. |
