Defining the World
The world mark-up collects the description of all bulks and computation domains defined in the simulation.
Only one world may be defined, but this world may contain several bulk compartments and computationDomain domains, each with a different name. Though when simulating a chemostat scenario, the name of the bulk MUST be "chemostat" regardless of the corresponding computationDomain name.
The Bulk and Computational Domain compartments are described in more detail in these sections (Click if you're viewing this on the wiki or turn over if you're reading the PDF). Make sure you are familiar with these before continuing:
