Mapping CFD Data to a STL Geometry in Paraview Using Stallion 3D

 


Here are instructions on how to import a surface CSV file from Stallion 3D into ParaView using the Point Dataset Interpolator:*

In Stallion 3D

  • Export the computational fluids dynamics (CFD) surface data as a CSV file
  • Export the volume data also as a CSV file

Open ParaView.

  • Click "File" > "Open".
  • Navigate to your CSV file and select it.
  •  Click "OK".

Convert CSV to points:

  •  In the "Pipeline Browser", click on the CSV file.
  • -Click "Filters" > "Alphabetical" > "Table To Points".
  • -Set "X Column", "Y Column", and "Z Column" to the appropriate column names in your CSV file.
  • Click " OK".

Load the target surface mesh:

  • Click "File" > "Open".
  • Navigate to your surface mesh file (e.g., VTK, STL, OBJ) and select it.
  • Click "OK".

 Apply Point Dataset Interpolator:

  • Click on the "Table To Points" output in the "Pipeline Browser".
  • Click "Filters" > "Alphabetical" > "Point Dataset Interpolator".
  • Set "Source" to the target surface mesh.
  • Set "Input" to the "Table To Points" output.
  • Click "Apply".

5. Visualize:

  • Click on the "Point Dataset Interpolator" output in the "Pipeline Browser".
  • The interpolated data should now be mapped onto the surface mesh.
  • Use ParaView's rendering and visualization options to create the desired visual representation.

3DFoil is Wing Aerodynamics Made Easy 🙏

Why use 3DFoil 🤔

There are several reasons why you might use 3DFoil for wing analysis:

  • Accuracy: 3DFoil is known for its accuracy in predicting the lift, drag, and moments of 3D wings. This is due to its use of a novel numerical algorithm that couples the vortex lattice method with a linear strength panel method.
  • Speed: 3DFoil is a very fast software package, making it ideal for parametric studies and optimization.
  • Ease of use: 3DFoil has a user-friendly interface that makes it easy to set up and run simulations.
  • Affordability: 3DFoil is relatively affordable, making it a good option for students and hobbyists.

Here are some specific examples of when you might want to use 3DFoil:

  • To design a new wing for an aircraft or other vehicle
  • To analyze the performance of an existing wing design
  • To troubleshoot problems with an existing wing design
  • To optimize a wing design for a specific performance goal
  • To educate yourself about the principles of wing aerodynamics

If you are looking for an accurate, fast, and easy-to-use wing analysis software package, 3DFoil is a good option to consider.

Here are some additional benefits of using 3DFoil:

  • 3DFoil can be used to analyze wings with taper, twist, dihedral angles, and sweep.
  • 3DFoil can be used to analyze wings with multiple airfoils.
  • 3DFoil provides a variety of visualization options, including contour plots and graphs.
  • 3DFoil is actively developed and supported by Hanley Innovations.

Overall, 3DFoil is a good choice for wing analysis if you are looking for an accurate, fast, and easy-to-use software package.

Aerodynamics of a golf ball

 Stallion 3D is an aerodynamics analysis software package that can be used to analyze golf balls in flight. The software runs on MS Windows 10 & 11 and can compute the lift, drag and moment coefficients to determine the trajectory.  The STL file, even with dimples, can be read directly into Stallion 3D for analysis.


What we learn from the aerodynamics:

  • The spinning golf ball produces lift and drag similar to an airplane wing
  • Trailing vortices can be seen at the "wing tips"
  • The extra lift helps the ball to travel further

Stallion 3D strengths are:

  • The built-in Reynolds Averaged Navier-Stokes equations provide high fidelity CFD solutions
  • The grid is generated automatically 
  • Built-in  menus are used to specify speed, angle, altitude and even spin
  • Built-in visualization
  • The numbers are generated to compute the trajectory of the ball
  • The software runs on your laptop or desktop under Windows 7, 10 and 11

Accurate Aircraft Performance Predictions using Stallion 3D



Stallion 3D uses your CAD design to simulate the performance of your aircraft.  This enables you to verify your design and compute quantities such as cruise speed, power required and range at a given cruise altitude. Stallion 3D is used to optimize the design before moving forward with building and testing prototypes.

The table below shows the results of Stallion 3D around the cruise angles of attack of the Cessna 402c aircraft.  The CAD design can be obtained from the OpenVSP hangar.


The results were obtained by simulating 5 angles of attack in Stallion 3D on an ordinary laptop computer running MS Windows 10 .  Given the aircraft geometry and flight conditions, Stallion 3D computed the CL, CD, L/D and other aerodynamic quantities.  With this accurate aerodynamics results, the preliminary performance data such as cruise speed, power, range and endurance can be obtained.

Lift Coefficient versus Angle of Attack computed with Stallion 3D


Lift to Drag Ratio versus True Airspeed at 10,000 feet


Power Required versus True Airspeed at 10,000 feet

The Stallion 3D results shows good agreement with the published data for the Cessna 402.  For example, the cruse speed of the aircraft at 10,000 feet is around 140 knots. This coincides with the speed at the maximum L/D (best range) shown in the graph and table above.

5 Tips For Excellent Aerodynamic Analysis and Design

Stallion 3D analysis of Uber Elevate eCRM-100 model

Being the best aerodynamics engineer requires meticulous planning and execution.  Here are 5 steps you can following to start your journey to being one of the best aerodynamicist.

1.  Airfoils analysis (VisualFoil) - the wing will not be better than the airfoil. Start with the best airfoil for the design.

2.  Wing analysis (3Dfoil) - know the benefits/limits of taper, geometric & aerodynamic twist, dihedral angles, sweep, induced drag and aspect ratio.

3. Stability analysis (3Dfoil) - longitudinal & lateral static & dynamic stability analysis.  If the airplane is not stable, it might not fly (well).

4. High Lift (MultiElement Airfoils) - airfoil arrangements can do wonders for takeoff, climb, cruise and landing.

5. Analyze the whole arrangement (Stallion 3D) - this is the best information you will get until you flight test the design.
