Evaluating solutions

Solution to a problem.

(::Solution)(r, t)
(::Solution)(o)

Evaluate the solution.

Properties

• retcode: termination status of the solver. See ReturnCode.
• i: initial value.
• b: boundary value.
• d_dob: o-derivative at the boundary, where o is the Boltzmann variable. See also o.
• ob: boundary constant. See also rb.
• oi: for o≥oi, the solution evaluates to the initial value.
• prob: problem solved.
• alg: algorithm used.
• original: original solution object, if applicable.
