Use this command to specify the initial condition for solute transport by defining the initial spatial distribution of the concentration over the flow region. The initial condition is given in two steps. First, a certain spatial region is selected with the mouse. Next, the value of the concentration, c, assigned as initial condition to a selected region is specified in the pop-up window. The initial condition can be imported from the results of a previous application using the Import Initial Conditions command.
