Calculate a representative position for the fluid in a cell. There are three positions that can be computed: cell center, fluid center of mass, and interface barycenter.
The following input ports are available:
| Input | Description | Type | Remark |
|---|---|---|---|
| Grid | Grid containing fields representing fluids in a multiphase setting. | Rectilinear Grid |
The grid contains the following data fields:
| Data field | Description | Data | Type | Remark |
|---|---|---|---|---|
| Volume of fluid field | A volume of fluid field, whose entries are in the range [0, 1]. | Scalar | Cell-based | |
| Interface gradients | Gradients in interface cells. | Vector | Cell-based |
The following parameters can be set by the user:
| Parameter | Description | Type | Accepted values | Default value |
|---|---|---|---|---|
| Position type | Choose the position type as either cell center, fluid center of mass, or interface barycenter. | Enumeration | Cell center, Fluid center, Interface | Cell center |
The following output ports are available:
| Input | Description | Type | Remark |
|---|---|---|---|
| Grid | A copy of the input grid. | Rectilinear Grid | |
| Positions | A set of points representing the calculated positions. | Polydata |
The following data fields are appended to the input grid:
| Data field | Description | Data | Type | Remark |
|---|---|---|---|---|
| Fluid position | The representative position of the fluid within a cell. | Vector | Cell-based |
The grid itself is not modified.
The points representing the positions do not have any attributes attached.
