-In dictionary `setFields`, dictionary `defaultValue` defines the initial value for particle fields (here, `velocity`, `acceleration`, `rotVelocity`, and `shapeName`). Note that `shapeName` field should be consistent with the name of shape that you later set for shapes (here one shape with name `sphere1`).

-In the dictionary `surfaces` you can define all the surfaces (shell) in the simulation. Two main options are available: built-in geometries in PhasicFlow, and providing surfaces with stl file. Here we use built-in geometries. In `cylinder` dictionary, a cylindrical shell with end helix, `material` name `prop1`, `motion` component `none` is defined. `helix` define  plane helix at center of  cylindrical shell, `material` name `prop1` and `motion` component `rotAxis`.
