Hello!
I am simulating a wave, using OpenFOAM, however I am having problems with reflections in the tank. To solve this problem I am trying to apply the damping, but without success. I would like to know about the lambda coefficient used fvoptions in vertical damping. How to know the correct value to use? In the tutorial the value is 0.5, but it does not work for my wave. Wave used: ************ { **************** length 65.4; **************** amplitude 0.5; **************** phase 0; **************** angle 0; } option1 { type verticalDamping; selectionMode all; origin (250 0 0); direction (1 0 0); ramp { type halfCosineRamp; start 0; duration 600; } lambda 0.5; timeStart 0; duration 1e6; } Thank you! |
