| Abstract | In this course various (astro)physical problems will be solved with diverse computational methods: Fourier-transformation, population synthesis & Markov chain Monte Carlo, N-body simulations, Hydrodynamical/Computational fluid dynamics simulations, High Performance Computing, radiative transfer, advanced visualization techniques. |
| Objective | We review the various computational methods used in (astro)physics, with a problem-oriented approach: we take an astrophysical problem and discuss how to solve that type of problem numerically. We will do data analysis, computer simulations, and visualization approaches that are not only used in astrophysics, but other physical fields, mathematical fields and engineering. |
| Content | - advanced linux terminal commands & scripts, e.g. how to use awk as a computing tool, how to manipulate big data with shell scripts - astronomical databases and archives to retrieve data for computations & statistics - Gnuplot as a visualization and computing tool - time series analysis (Discrete Fourier Transformation, power spectrum, box-fitting least square) - population synthesis & Markov chain Monte Carlo - N-body simulations - hydrodynamical/computational fluid dynamics simulations (various methods, mesh refinement) - 3D visualization and rendering with Paraview, streamline integration, animations - basics of High Performance Computing - Radiative Transfer with flux limited diffusion approx, role of opacity, opacity considerations and computations; Radiative transfer with ray-tracing approach (using RADMC-3D) |
| Prerequisites / Notice | basic linux terminal commands, basic programming knowledge in any language. |
