Method of lines and conservation of nonnegativity
Generally speaking, a parabolic problem conserves nonnegativity if nonnegative input data lead to a nonnegative solution. This property of the mathematical model is important in physics if we deal with absolute temperature, concentration, density etc. The well-known comparison principle guarantees t...
