TransAT Tutorial Manual 5.3. Transport of particles in a pipe

• In the text field below the drop-down list, set the name of the object to be created as
Cylinder

• Set the following parameters:

Base Center , X−coord . : −0.1 [m]
Base Center , Y−coord . : 0.0 [m]
Base Center , Z−coord . : 0.0 [m]
Radius : 0.0762 [m]
Cylinder Length : 1.724 [m]
Points on c i r c l e : 76

• Click .

• Check Resize Mesh around Geometry, to adjust the domain around the cylinder

• Click to create the Cylinder and send it to the mesh

Objects Tab
In this case the fluid region is enclosed in the geometry that was just loaded. Bearing in mind
that in TransAT, loaded objects are considered as solids by default, the fluid and solid domain
need to be inverted. To do so,

• Click the Objects tab.

• Select the Cylinder object that appeared in the list of objects. Make sure the Cylinder is
coloured in orange in the Graphical window

• Under the Object Properties, find Set CAD as Solid
• Un-check Set CAD as Solid to define the Cylinder as the flow domain

5.3.7 Mesh & BCs Tab

The computational domain is defined and the mesh is created in the Mesh & BCs tab.
• Select the Mesh & BCs tab at the top of TransATUI if that is not already the case.
