Set up a simple multiphase gearbox for drive train oiling simulation using SimLab for
CFD-nanoFluidX solution. Oil distribution will be analyzed
and torques and forces will be computed.
Note: A PDF version of this tutorial is available in the Model
Files section.
In this lesson you will learn how to:
Select unit system
Import CAD geometry (*.x_b)
Define SPH flow solution
Prepare the geometry for simulation
Assign materials
Define domain (gravity)
Assign motion
Create reference node for fluid volume
Perform one-click SPH particles creation
Review conflicting fluid particles
Set solver settings and result requests
Data check
Export particle and configuration files
Save a SimLab database (*.slb)
The model is a simple gearbox with two gears of radius 62.5 mm
(Output_Gear) and 20.0 mm (Input_Gear). We will create a
1.0 sec multiphase simulation at a resolution of
1.0 mm. Input speed will be 1000 rpm. Figure 1.
