**Syntax**

` >>> SIMULATION: mtough2`

**Parent Command**

` >> CONVERGE`

**Subcommand**

` -`

**Description**

This command limits the number of TOUGH2 simulations performed during an inversion. A rough estimate of the total number of TOUGH2 simulations during an inversion can be made given the number of iterations requested (see command `>>> ITERATION)` and the type of finite difference quotients calculated (see commands `>>> FORWARD` and `>>> CENTERED).` However, there is an unknown number of unsuccessful steps that cannot be accounted for. The maximum number of TOUGH2 simulations may also be limited in order to stop and examine a specific simulation that leads to convergence problems (see command `>>> INCOMPLETE).` If performing Monte Carlo simulations (see command `>>> MONTE` CARLO), *mtough2* is the number of parameter sets generated and thus the number of realizations of the calculated system output.

**Example**

` > COMPUTATION
>> STOP after
>>> a total of : 500 TOUGH2 SIMULATIONS
<<<
>> ERROR analysis
>>> MONTE CARLO
<<<
<<`
