Properties

Usage

The option is specified using:

disk1
{
    type            tabulatedAccelerationSource;
    selectionMode   cellSet;
    cellSet         sourceCells1;
    fields          (U);

    timeDataFileName "constant/acceleration-terms.dat";
}

The timeDataFileName provides the name of a file containing a list of the motion as a function of time, e.g.:

//     t      acc    omega   dOmegadt
(
    ( 0.0  ((1 0 0) (0 0 0) (0 0 0)))
    (10.0  ((2 0 0) (0 0 0) (0 0 0)))
);

where:

• t = time [s]
• acc = acceleration vector [m/s2]
• omega = rotation vector [rad/s]
• dOmegadt = angular acceleration [rad/s2]
