Initial Values

This 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.

Domain Selection

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.

Initial Values

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