AB In this article, we report several techniques for improving the efficiency and accuracy of a precorrected fast Fourier transform (FFT)-accelerated solver for the computation of fluid drag forces on micromachined devices using a boundary element discretization of the integral form of the incompressible Stokes flow equations. The boundary element formulation necessitates the discretization of the surface of the device using a large number of &quot;panels,&quot; whose interactions are coupled by multidimensional Stokes kernels. The resulting &quot;<i>n</i>-body&quot; problem generates dense matrices that can be solved in <i>O</i>(<i>n</i> log <i>n</i>) complexity using a precorrected FFT approach, where <i>n</i> is the number of panels used in discretizing the surface of the device.
