Initial Values
The Initial Values node adds initial values for the number density, pressure, and density. For the transient solver, these values define the state of the problem at the initial time step; for the stationary solver, they serve as a starting point for the nonlinear solver.
Initial Values
Select an option for each of the following from the Initialization list and then enter a value or expression in the field. Select:
•
Initial number density to enter a Number density n0 (SI unit: 1/m3).
•
Initial pressure to enter a Pressure p0 (SI unit: Pa).
•
Initial density to enter a Density ρ0 (SI unit: kg/m3).
