Model Wizard
Note:
These instructions are for the user interface on Windows but apply, with minor differences, also to Linux and Mac.
1
To start the software, double-click the COMSOL icon on the desktop. When the software opens, you can choose to use the Model Wizard
to create a new COMSOL model or Blank Model
to create one manually. For this tutorial, click the Model Wizard
button.
If COMSOL is already open, you can start the Model Wizard by selecting New
from the File menu and then click Model Wizard
.
The Model Wizard guides you through the first steps of setting up an application. The next window lets you select the dimension of the modeling space.
2
In the Select Space Dimension window click the 3D button
.
3
In the Select Physics tree under Fluid Flow
> Single-Phase Flow
, click Laminar Flow
.
Even though this is a particle tracing model, the first step is to solve for the fluid velocity field, which will then be used to exert a drag force on the particles. The Particle Tracing for Fluid Flow interface
will be added later.

Click Add.
5
Click the Study
button.
6
In the tree under General Studies, click Stationary
. Although the particles are moving through the channel over time, the fluid velocity at any fixed point does not change over time, making a stationary analysis possible.
