Abstract: In this paper, an error-controlled hybrid adaptive fast solver that combine both O(N) and O(N log N) scheme is proposed. For a given accuracy, the adaptive solver is used in the context of regularized vortex methods to optimize the speed of the velocity and vortex stretching calculation. This is accomplished by introducing three critical numbers in order to limit the depth of the tree division and to balance the near-field and far-field calculations for any hardware architecture. The adaptive solver is analyzed in term of speed and accuracy.
