Calculate the gradient in interface cells, i.e., in cells where the volume of fluid (VOF) value is larger than 0 and smaller than 1.
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 |
The following data fields are appended to the input grid:
| Data field | Description | Data | Type | Remark |
|---|---|---|---|---|
| Interface gradient | Within interface cells, it contains the computed gradient, elsewhere it is set to a zero-vector. | Vector | Cell-based |
The grid itself is not modified.
