Currently, all of collocation and memory allocation are built into Continuity. It use to be hat you would have to re-compile Continuity with some special flags to get collocation to work. This is no longer the case. 10.2 Continuity Commands Cardiac propagation problems in Continuity are set up and solved by entering a series of commands. Commands may be typed at the Continuity prompt or read from a command file.
Continuity solves many problems and implements a large number of commands.
However, only a subset of these are used for propagation problems. This section kindly provided by Dr. Jack M. Rogers. 10.3 Propagation Commands Almost all commands used in propagation are described below in roughly the order they are used to perform a simulation. Need not be used if Xj coordinates are 2D Cartesian. Propagation problems must be solved in Cartesian coordinates.
