TransAT Tutorial Manual 5.1. Particles in Crossflow

Nz : 2
Cell Ratio : 1.0
Maximal Ratio : 1

The ratios between cells has been set to 1 so as to obtain a uniform grid.

Blocks
The domain must now be decomposed into several blocks so that the simulation can run on
several processors. Indeed, each block is allocated to one processor (but a processor can handle
several blocks).

• Select Blocks to define the multi-block options.

• Click to cut the domain into several computational blocks.

• Set X direction input to 3 then click .

The domain is automatically cut into blocks of equivalent sizes.

BCs Tab
To see the surfaces of all or each of the boundaries, choose a boundary in the drop-down list at
the top of the BCs tab. One boundary condition of each type is available to be edited and used
from the start. Additional BCs can be created by clicking on . is used to assign a selected
BC to a highlighted surface.

Creating and assigning Boundary Conditions:
To create the inflow at the boundary on the left-hand side of the domain ( i.e. X min) follow the
instructions given below:

• One of each type of boundary condition are already available at the start. This tutorial will
use each type of available BCs.

• Click of the Inflow BC. Set the properties of the boundary condition

• Fill in the inflow properties:
– Inflow Data Source: From BC

– Inflow Type: Velocity based
