I am new user of Mathematica. I am trying to get analytical solution of heat conduction equation in cylindrical coordinates in Mathematica. I wrote script and saved it as '.m' file. To run program I clicked on 'Run package' button on top right of work bench window.
Problem I am facing is I got correct results sometimes within 2-3 minutes. At other times, program keep on running for several hours. Sometimes, it only displays "General::stop: "Further output of will be suppressed during this calculation." and does not give results later.
I would like to know why I am getting inconsistent results and how to rectify them. I have also attached program script file 'heateqn_cyl.m'
Thanks and regards,
