Properties🔗

• Implicit
• Second order
• Transient
• Boundedness not guaranteed
• Conditionally stable

\[\ddt{\phi} = \frac{1}{\Delta t} \left( \frac{3}{2}\phi - 2 \old{\phi} + \frac{1}{2}\oldold{\phi}\right)\]

Usage🔗

The scheme is specified using:

ddtSchemes
{
    default         backward;
    ddt(phi)        backward;
}
