Blocks
To allow parallel computation, the domain must be split into several blocks.

• Click
• Enter number of blocks in each direction as the following then click

X d i r e c t i o n : 4
Y d i r e c t i o n : 1
Z d i r e c t i o n : 1

BCs Tab

• Select BCs tab.

Creating Boundary Conditions:
In this case, an inflow should be assigned at Z min, another inflow at Z max, an OlgaCoupling
at X max, and Symmetry boundary conditions for other boundaries. Below is a step-by-step
instruction, how to create all the boundary conditions and to define their properties, starting
with the water inflow boundary condition.

• Rename the Inflow to water inflow

• Click to set the properties of the boundary condition

• Fill in the inflow properties as follows:

– Inflow Data Source: From BC
– Inflow Type: Velocity based
– Inflow Profile: Laminar
– Inflow Velocity Components: u: 0.0 v: 0.0 w: 0.0

– Inflow Temperature: 300
• Select the N-Phases Algebraic Slip Model tab on the left-hand side of the inflow prop-
erties window, then set:

– Inflow Volume Fraction of phase 3: 1.0
– Phase 1 Velocity [m/s]: u: 0.0, v: 0.0, w: 1.22
– Phase 2 Velocity [m/s]: u: 0.0, v: 0.0, w: 1.22

– Phase 3 Velocity [m/s]: u: 0.0, v: 0.0, w: 1.22
