The number of timesteps to wait after a decrease in the timestep due to failed solver before increasing the time step.

## Synopsis#

#include "petscts.h"


Logicially Collective

## Input Parameters#

• cnt - the number of timesteps

## Options Database Key#

• -ts_adapt_time_step_increase_delay cnt - number of steps to delay the increase

## Notes#

This is to prevent an adaptor from bouncing back and forth between two nearby timesteps. The default is 0.

The successful use of this option is problem dependent

## Developer Note#

There is no theory to support this option
