Uniform initializationΒΆ

Uniform initialization assigns the prescribed value for a flow variable over the complete domain/mesh as the initial condition before the beginning of the simulation.

This value, depending on the type of the variable that can be a scalar or vector.


It is recommended to set the value close to the expected solution to enhance the convergence behavior.


For Multi-Phase flows, a uniform ‘phase-fraction’ would mean that the complete domain/mesh is initially (before the begining of the simulation) filled with the fluid material of the specified phase value.
