Fill Subcycle

Fill Subcycle = <integer>

Description / Usage

This is an optional card that sets the number of subcycle-fill time steps between fluidflow time steps in uncoupled level set calculations. The default is 10 subcycle time steps for every flow time step. The input parameter is defined as

<integer>

Any nonzero number indicating the subcycling frequency of the fill equation versus the flow equations.

For example, if the value of <integer> is 1, the flow and fill equations are solved every time step. If it is 10, between every transient step in the flow calculation, the fill (advection) equation is solved 10 times with one-tenth of the time step.

Examples

The following is a sample card that sets the fill subcycling rate to 4:

Fill Subcycle = 4
