The Run Options command in the FEMWATER menu brings up the Run Options dialog. This dialog is used to enter a set of general analysis options.
Three options are available for designating the type of simulations to be performed by FEMWATER:
This option is used to perform a steady state or transient flow simulation.
For this case, a steady state or transient flow simulation must be performed prior to the transport simulation. The results of this simulation (velocity and moisture content) are then input to FEMWATER as a flow solution initial condition.
With a coupled flow and transport simulation, either density-dependent flow or density-independent flow can be simulated. This option is controlled by entering the appropriate parameters defining the relationship between concentration and density and concentration and viscosity. These parameters are entered in the Fluid Properties dialog.
FEMWATER can be run in either a steady state or transient mode. The steady state mode is only allowed when the Flow only option has been selected.
The Units button brings up the Units dialog. This dialog is used to enter the units for length, time, concentration, etc. for the simulation. GMS uses the selected unit options to display the appropriate units next to each input edit field in the other FEMWATER dialogs.
The remaining run options are described in the FEMWATER Reference Manual. In most cases, the default values are appropriate.
