Hi all,
I have only been working with OpenFoam for the past few days but have worked with FLUENT before. The simulation is of 2D water flow past three pillars in a freestream with an absolute pressure of 50.27bar I am confused what free stream boundary conditions I should be using, preferably for use with k-epsilon My current BC are inlet (note, internalField is (1 0 0)) U: type fixedValue; freestreamValue $internalField; P: type zeroGradient; k: type fixedValue; value uniform 18.375; epsilon: type fixedValue; value uniform 3.6975; outlet U: type zeroGradient; P: type fixedValue; value $internalField (set as 50.27e5) k: type zeroGradient; epsilon: type zeroGradient; symmetry 1,2,3,4 type symmetryPlane for all wall 1,2,3 U: type fixedValue; value uniform (0 0 0); P: type zeroGradient; k: type zeroGradient epsilon: type zeroGradient I have been trying to adjust tutorials to fit my setup, but so far nothing is working. Please be as brutal and honest as necessary, I'm sure all of this is complete garbage... but I just want to start understanding where I'm going wrong. Thanks, Ed Edit: the error message that I get now is: PHP Code:
