  - Anisotropic Volume Meshing: Onera M6 Wing
    When meshing aerospace geometries such as wings, propeller blades, or turbine blades, you are required to generate a very fine mesh that adequately captures the curvature of the leading and trailing edges. To help reduce the cell count while maintaining solution accuracy, Simcenter STAR-CCM+ provides an anisotropic meshing option by which you can refine these edges.

To determine when the problem has converged, plot the lift and drag coefficients.

Use the following steps:

Right-click the Reports node and select New > Flow / Energy > Force Coefficient.
A new report node named Force Coefficient 1 is created.
Rename this node Drag Coefficient

Select the Drag Coefficient node and set the following properties:


Property	Setting
Reference Density	1.177 kg/m^3
Reference Velocity	252 m/s
Parts	Regions > Overset 2D > Airfoil

Right-click the Drag Coefficient node and select Create Monitor and Plot from Report.
A new plot node appears named Drag Coefficient Monitor Plot.
Create a lift coefficient report.
1. Copy and paste the Drag Coefficient node onto the Reports node.
2. Rename the new Drag Coefficient copy node to Lift Coefficient.
3. Select the Lift Coefficient report and in the Properties dialog, set Direction to [0.0, 1.0, 0.0].
Right-click the Lift Coefficient node and select Create Monitor and Plot from Report.
A new plot node appears named Lift Coefficient Monitor Plot.
Save the simulation.
