The seismic wizard computes the g-factors for the three global directions and defines the uniform load vector on the selected element. The wizard uses the specified height of the associated support elevation of the element to compute the seismic coefficient distribution factor (µ). The computed uniform load vector is applied (that is, carried forward) to all subsequent elements until changed. If the support elevation changes or if the support is a vessel, you may need to use the wizard multiple times.
