In various embodiments, a user can create or generate objects to be modeled, simulated, andor rendered. The pellets have a density such that they may be moved through the equipment by system fluids passing therethrough. A DC voltage is applied across an anode coupled to the substrate side of the membrane and a cathode coupled to its other side so as to dissociate at least part of the steam, into protonic hydrogen and oxygen at said anode. In response to any primary process being in a fault state, the first monitor process resolves the fault state of each such primary process.
