Module: Gradient ()

Description:

The Gradient module computes the gradient of a field defined on a regular (i.e., uniform, rectilinear, or curvilinear) grid or on a tetrahedral grid . The output is a vector or tensor field defined on the same grid. The orientation of the gradient (vector) depends on the setting of port Output. If Force is selected the negative gradient vector is computed.

Press the Apply button to start the computation.

Connections:

Data [required]
Field defined on a regular grid or a vertex based tetrahedral grid.

Ports:

Result type

Selection of the result type. Depending on the type the result may be clamped. For unsigned types an appropriate offset will be added. This port is only shown if the input type is not float.

Output

If Force is selected the negative gradient vector is computed.
