Numeric Quadrature with Derivatives
4 votes

Although this thread is quite old, I thought it might be useful to have a reference to a peer-reviewed paper for generalizations of some common quadrature rules. Nenad Ujevic, "A generalization of ...

Vortex Panel Method implementation
2 votes

A very good start is the book: Low-Speed Aerodynamics by Joseph Katz and Allen Plotkin. It describes a variety of panel methods for airfoils and wings, and, best of all, it includes source code.

Is it common not to use libraries for standard numerical algorithms, and why?
1 votes

Several good reasons have been given by others for using libraries, and also for rolling your own routines. You can sometimes speed up computations for a specific application because you know in ...

Are there any general fluid dynamics frameworks?
1 votes

You might find that a general CFD "framework" might not be the best one for many engineering design problems. The Advanced Simulation Library (ASL) and OpenFoam (both recommended by others here) ...

Evaluating oscillatory integrals with many independent periods and no closed forms
1 votes

I have worked on simpler integrals where there are points of stationary phase. I found two methods that work quite well. One is to introduce an exponential damping factor that depends on the phase ...
