Download and extract the contents of the latest archive and the archive to a folder called "naca4412_wing". You can create the "naca4412_wing" folder anywhere. In this example the "naca4412_wing" folder is created in "D:\". Once you create the folder open a command prompt window and navigate to the folder.
Type dir and press enter to view the contents of the folder. You should see 4 files.
Type > apm-preprocessor-1.1.0-windows-amd64.exe naca4412_wing and press enter. The APM preprocessor will read the mesh and will create a .mdl file. Once the .mdl file is created, type > apm-solver-1.1.0-windows-amd64.exe naca4412_wingand press enter. The APM Solver will read the .mdl file and will solve for the potential flow around the NACA4412 wing. Once the solver finishes, you should see the following files in the "naca4412_wing" folder.
Once the files are loaded, click the apply button in the properties tab on the left. The wing and the wake will be shown in the visualisation window. You can change which variable is currently displayed by selecting a coloring dropdown value. The image below shows the NACA 4412 wing colored by the pressure coefficient.
Alternatively, you could use the APM Viewer to visualise the results. The APM Viewer opens a .json file containing the results. By default, the .json file output is disabled. You need to add the following option to the .conf file to enable .json file output.
If you haven't downloaded ParaView, go to . ParaView is an open-source, multi-platform data analysis and visualization application. Install and open ParaView. Then click on "File->Open" and select the "naca4412_wing_body_panels_..vtu" and "naca4412_wing_wake_panels_..vtu" files. Once you select the files click "Ok".
Run the solver again. Once the solver finishes, you should have a "naca4412_wing.json" file in the "naca4412_wing" folder. Go to and click the "Upload your model" button. Select the "naca4412_wing.json" file and click the "Open" button. The image below shows the NACA4412 wing results visualised with the APM Viewer.
