Detailed Description

Solution represents the solution currently being computed. It contains element data and current (latest) initial value. In many ways a Solution is similar to a Function (ODEFunction), but differs in a number of ways:

• It contains extra data (initial values) used to propagate the solution.
• It can do extrapolation.
• It can create new elements.
• It can save debug info to a file.
