HydroGeoSphere/Surface Loading

It is a nodal property, but because surface loading is applied to all nodes of a vertical column of nodes, only one node of the column needs to be chosen.

Specified stress variation

 * 1) npanel Number of panels in the time-variable specified stress function. For each panel, enter the following:
 * (a) ton_val, bc_val Time on [T] and specified stress variation [L T−1].

Chosen nodes in the currently active media (see Section 5.8.1) are assigned a time-variable specified stress variation value. The specified stress variation value corresponds to the term:



\frac{{\partial}({\sigma}_{zz}/{\rho}g)}{{\partial}t} $$   (Equation 5.10)

which has units of [L T−1] and corresponds to an equivalent freshwater head change per unit time.

Specified stress variation from file

 * 1) fname Name of the file which contains the list of nodes to which specified stress variation will be assigned. It should contain the following data for each node:
 * 2) nde, npanel Node number, number of panels
 * (a) ton_val, bc_val Time on [T], stress variation [L T−1].

Nodes listed in the file and in the currently active media (see Section 5.8.1) are assigned a unique stress variation value. The specified stress variation value is described in the previous command.

Echo 1d loading conditions
If this command is included in the input file, a listing of the loading conditions will be issued in the prefixo.eco file.
