Maximum Time Step

Maximum time step = <float>

Description / Usage

This card sets the value of the maximum allowable time step size in a transient analysis, where the input parameter is defined as

<float>

Any floating point number in the same units as specified in the delta_t card.

Examples

A sample card that sets the maximum time step to 10.0 follows:

Maximum time step = 10.0

Technical Discussion

This setting is useful for advection dominated simulations, such as FILL, where a Courant-like limit must be set on the value of the time step for optimal performance.
