Computing the virtual human

To simulate the complex processes within a human, models of the organs comprising a human are being developed. As well as accurate geometry these models include physiology to represent chemical, electrical, mechanical and fluid based processes. For a model representing the heart all these processes are coupled together. The cellular processes are modelled on a cellular spatial scale, which is very different from the scale for solving the mechanics or electrical activation of the whole heart organ. The methods for coupling these different scales are being developed.
