The Initial Values node specifies the initial values for the concentration of each species. These serve as an initial guess for a stationary solver or as initial conditions for a transient simulation.

If there are several types of domains with different initial values defined, it might be necessary to remove some domains from the selection. These are then defined in an additional Initial Values node.

Enter a value or expression for the initial value of the Concentration or concentrations, ci. This also serves as a starting guess for stationary problems.
