domain

NAME

domain

SYNOPSIS

          domain x_{min} x_{max} y_{min} y_{max}

DESCRIPTION

domain creates the physical domain for the fluid dynamics calculations, $\Omega = [x_{min},x_{max}] \times [y_{min},y_{max}]$. domain requires four arguments.

• x_min - x coordinate of the lower left corner
• x_max - x coordinate of the upper right corner
• y_min - y coordinate of the lower left corner
• y_max - y coordinate of the upper right corner

domain has no optional arguments. IBIS requires that the aspect ratio

$$\frac{x_{max}-x_{min}}{y_{max}-y_{min}}$$

be a power of 2.

EXAMPLE

          domain 0.00 4.00 0.00 2.00

The physical domain is $(0,4)\times(0,2)$.
