Opens the files <part>_thermal.out, <part>_mechanical.out, and <part>_mechanical_recoater.txt in which you can review the progress of the simulation through different stages, and see any errors and warnings that arose.
These log files are an invaluable diagnostic tool. Especially notable are errors that prevent the simulation from completing, and warnings such as recoater blade interface and support structure failure. It is a good practice to check these logs during or after every simulation. If the simulation does not complete, the log files open automatically.
