when i running the solver, there is a convergence history monitor.
Can you explain the meaning of the graph, what is the meaning of magnitude in iteration step to relative change?
And the next problem, when i start the post processor Sometimes it is successfully work but sometimes it doesn't work and log window says:

what is the problem with my simulation? I use elmer 7.0 under windows 7
