General options

General Options is under Model Build → General Settings. It has only one line of input. The first item is checked if the model is steady-state and not checked if the model is transient. To simulate storage fluxes in transient models, spatially-variable area sinks (SVAS) are required. If you try to solve a transient model without any SVAS, Anaqsim gives an error message.

The other three items are text values that document the length and time units used in the model, and provide comments to document the run. The model uses consistent length and time units throughout. For example, if you chose meters and days, then hydraulic conductivity, specific discharge, and average linear velocity are in m/day, well discharges are in m3/day, and time markers on pathlines are in days. The default convergence settings in Check Settings are based on units of either feet and days, or metres and days. If other units are used, such as centimetres and seconds, the convergence settings should be updated accordingly.
