$CourantFactor

Format

$CourantFactor
 S                // where S is an floating point and $\begin{smallmatrix}{\color{OliveGreen}S\ \leq\ 1.0}\end{smallmatrix}$.

$\Delta t = \frac{S}{c\sqrt{\frac{1}{{\Delta x}^2}+\frac{1}{{\Delta y}^2}+\frac{1}{{\Delta z}^2}}}$

Where c is the light speed in the vacuum, you can see more details in Eq. 4.60.
The default value is 0.999999.
Note: S is not equal to the courant number.

Example

$CourantFactor
 0.999

Then S will be 0.999.

Example

$CourantFactor
 3    1500e-9

This means the program has 2 objects in the simulation.
