#### Partial Differential Equations – A brief introduction

Since my studies currently involve a lot of partial differential equations (PDEs) I thought a brief introduction might be in order. I’ll start by introducing ordinary differential equations (ODEs) first, since they are in many ways very similar. When you solve an ordinary equation like $$2x^2 – 3x = 5$$ you want to …

#### Fluid simulation in Blender

Finally found some time to experiment with Blender’s Fluid simulator. Very easy to use, however I quickly discovered that an OpenMP enabled build would have been preferable, as well as a x64 version. I started simple with a drop hitting the floor, and rendered it using LuxRender. My poor Q6600 spent roughly 80 cpu-hours on it. …
