Hi everyone, I am now trying to solve a partial differential equation which is similar to the three dimensional Poisson’s equation but with complex numbers. The equation is the result of the transformation of a set of fluid dynamic equations from time domain to frequency domain. I have Dirichlet boundary conditions all over the boundaries. The coefficient matrix that obtained by finite volume method (with collocated grid) is made of complex numbers. I would like to know that, for my discretized equation which solver and PC are the most suitable to work with. And BTW, the solution should be done in parallel with about 10^4 - 10^6 unknowns.
It is the first time for me to solve equations with complex numbers, however, I am not so good at mathematics involving complex number. I would like to know want should I bear in mind throughout the whole process? Any suggestions or comments are appreciated. Thanks! HU Yaoyu
