I am a PhD student in Westlake University now, under the supervision of Prof. Sergio Torres. My research interests include: (i) simulation of flow and particle transport in fracture networks; (ii) GPU-acceleration for high performance computating; (iii) application of percolation theory; and so on. I am developing an in-house (C++ and cuda) code which is able to do: (i) discrete fracture network (DFN) representation, (ii) stead-state flow simulation in DFNs (with the mixed hybrid finite element method), and (iii) random walk particle movement (still debuging). The code aims at running Monte Carlo simulations with e.g. super computer, and may be released publicly in the future.
