Using RK4

The RK4 node, with its own properties, is automatically added as a subnode of a specific streamline derived part node when 4th-Order RK is specified for the Integration Solver property of the streamline.

RK4 Properties

Integration Direction

Specifies the direction of integration from the seed location.

 

Forward

The integration proceeds in the forward direction (for instance with the flow if velocity is the vector field).

 

Backward

The integration proceeds in the backward direction (for instance against the flow if velocity is the vector field).

 

Both

The integration proceeds both forward and backward from the seed location.

     

RK4 Expert Properties

Initial Integration Step

The initial integration step size in units of cell length.

     

Maximum Propagation

The maximum length of the streamlines in units of cell length.

     

Max Steps

The maximum number of integration steps.
