update comment in tabulatedAccelerationSource
Information about the file structure were missing in the comments and the documentation seems outdated:
Usage
Example usage:
\verbatim
SBM
{
type tabulatedAccelerationSource;
active yes;
timeDataFileName "constant/acceleration-terms.dat";
}
cat constant/acceleration-terms.dat:
2
( t acc omega dOmegadt
(0.0 ((1 0 0) (0 0 0) (0 0 0)))
(10 ((2 0 0) (0 0 0) (0 0 0)))
)
t = time [s]
acc = acceleration vector [m/s2]
omega = rotation vector [rad/s]
dOmegadt = angular acceleration [rad/s2]
details see tabulatedAccelerationSourceTemplates.C
