Introduction The tools: pyFoam in 3 minutes The tools: swak4Foam - 3 more minutes Case study: Taylor-Green vortex Case study: Pitz-Daily CTest Conclusion The detachment point Basic case Adding data to the case Additional tests • The point where the flow on the lower wall reverses its direction • approximate location is shown on the next picture by a red dot • To find it Ignaz looks for the face on the lower wall which has 1 a negative x-component of the velocity 2 the largest x-coordinate • On the next slide a graph of the x-component of the flow is shown • sampled on the green line in the picture above • the point Ignaz is looking for is where the black line crosses the beige line Bernhard F.W.
