Hello,


In order to validate the flow around an airfoil I need to calculate the static pressure coefficient at several locations.
How can I do this within Openfoam, using pressure functions. I don't understand how to set it up correctly.


Thanks!

Hello Lars,

You can use the pressure function object to compute the static pressure coefficient. This will compute a new variable. The exact setup may vary depending on which OpenFOAM branch/version you are using:

• OpenCFD branch (openfoam.com): https://doc.openfoam.com/2306/tools/...ield/pressure/
• OpenFOAM foundation (openfoam.org): https://github.com/OpenFOAM/OpenFOAM...ure/pressure.H

Then you can use the probes function object to retrieve the values on the desired locations. Or use the sampling functions to extract it along a line, etc...

Regards,
Yann
