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.
