Hello,
i have a problem by dimension in result of volPointInterpolate(p). In Result are factor 1000. The result of volPointInterpolate(U) - velocity distribution - are plausible. What can be my mistake? Whats the problem? About informations I'm very happy. Greeting Markus http://picfu.net/83d2bc |

You are probably using a solver like icoFoam or simpleFoam, in which the pressure is a dynamic pressure in m^2/s^2, rather than in Pascal.
Have a look at 0/p under dimensions: [mass length time ...] to see if I'm right. If so, AND your fluid density is ~1000 km/m^3, all is clear. Good luck, Hrv

Hello,
thanks for the informations. I use openFoam 1.4.1 and solver turbFoam. Quote:
