Class
Foam::Function1s::crankConnectingRodMotion
Description
Crank and connecting-rod motion function for piston engines etc.
\c value returns the current piston position as a function of
the crank-angle in degrees.
Usage:
\verbatim
<name>
{
type crankConnectingRodMotion;
conRodLength 0.2;
stroke 0.12;
}
\endverbatim
