of.boundary.nodal.acceleration

of.boundary.nodal.acceleration *nodal_tag* <string> x <double> y <double> r <double> xtable <string_tag> ytable <string_tag> rtable <string_tag>

Create the nodal acceleration boundary on the nodal groups. r is for the angular acceleration, in \(rad/s^2\). The acceleration can be time dependent if you use the table. The x, y, r values will be the factor if you use the table. That is \(a[i] = x \times table[i]\)

Parameters:

nodal_tag: tag of the group

x: (default 0.0) Acceleration in the x direction or the amplitude of x table.

y: (default 0.0) Acceleration in the y direction or the amplitude of y table.

r: (default 0.0) Angular acceleration.

xtable: (default -1) time dependent acceleration in x direction.

ytable: (default -1) time dependent acceleration in y direction.

rtable: (default -1) time dependent angular acceleration.

Example:

# ball will be give an acceleration of 100m/s^2
