It gives me errors just when loading it. Here are the errors. This is on 5.2, windows XP. http://12000.org/my_notes/LESolver/LESolver_errors.png I also tried to execute the documentation notebook itself which contains examples, parts of it worked, but many parts give many long errors and it seems to have went in a loop, but may be I should have waited a bit more. Any way, since the package is dated 1996, I can understand. I am not sure the original author is still at the email address shown there, but I am sending them a link to the above now. Nasser
