Yes, this is exactly what seems to be happening but except reversed, halfing the time step means that the temperature at each node is double (because the output seems to be independant of the timestep, so the only change that halfing the time step causes is doubling the iterations and therefore...
Homework Statement
I am working on a Matlab code that will solve a temperature grid for a 2D transient heat transfer problem. The code seemed to be working well but when I changed the timestep (to find timestep independance) I noticed that the larger the timestep, over the same duration, the...
