Dear Fluid-Dynamicists, I am somehow stuck with my study of the flow around a body. What do I want? I would like to have the flow around a car body with u=100km/h=27m/s. What did I do? I followed Oliver's advice: - create a 3D-shape - assign CFD boundary 'constrained/2D bounding plane' to front and ...

Sagt man bei Bierdeckel dazu? Bei uns sagt man Kronkorken.

Nach meinem Kenntnisstand kann man in SheetMetal nur etwas abwickeln, wenn es mit SheetMetal erzeugt wurde. Aber ich lass mich gerne belehren.

Hello, to use the FCGear workbench one has to have a knowledge of gears and gear construction in general. Even if you know the special expressions in German it is of no use as the English expressions are completely different. I am afraid you first have to learn something about gears. I'd recommend s...

But still i guess, the flow is simulated without a piston, - a engine don't have a outlet at this place... ;) ;) Hello Herb, when one is interested in the flow in the inlet channel and the flow around the valve you do not need a piston. It is more like a flow test bench where only the cylinder head...

A few streamlines are at an are inside the metall of the engine, especialy at pic 2. Why? Hello, I made a similar test a few months ago. The streamlines only seem to be outside. One has to cut at an angle to show the inside. Kind regards Helmut https://forum.freecadweb.org/viewtopic.php?f=37&t=...
