The UniformExcitation pattern allows the user to apply a uniform excitation to a model acting in a certain direction. The command is as follows:

pattern UniformExcitation $patternTag $dir -accel $tsTag <-vel0 $ver0>

$patternTag unique tag among load patterns
$dir direction in which ground motion acts
1 - corresponds to global X axis
2 - corresponds to global Y axis
3 - corresponds to global Z axis
$tsTag tag of the TimeSeries series defining the acceleration history.
vel0 optional, the initial velocity, default=0.0.

NOTES:

  1. The responses obtained from the nodes for this type of excitation are RELATIVE values, and not the absolute values obtained from a multi-support case.
