In computational physics we use simulations to understand experiments, and try to shed some light on the underlying processes. So how do we know if the code we're using is correct, and producing sensible results? The first way is to...

Mainly for my own records, I thought I could start writing short articles on thetools I find really useful in my work. It's somewhere to put links to useful pages,and notes on things to watch out for next time. First...

Although I'm a plasma physicist by training, I spend the majority of my research time at the moment programming whilst waiting for simulations to run. This is almost all numerical: A fair sized simulation code which runs on supercomputers like...
