Hello gus!I used the immersion boundary method of foam-extend 4.1 to calculate the fluctuation of the airfoil, and why the calculated thrust coefficient and drag coefficient changed very sharply, not a smooth sine wave.
In addition, when I solved, the number of iterations of the pressure equation was very large, between 400-1000 times, is it because p is inaccurate. Below are my controlDict and fvschems and fvsolutions files. Does anyone until how to fix this?Thank You! ![]() ![]() ![]() |
