Verbose thermal solver messaging

The thermal solver has the capacity of displaying different levels of messaging in the standard output, log file, and the MSGF file when you include the LEVEL OF VERBOSENESS OF MESSAGING OUTPUT advanced parameter into your solution.

  • Level 1 only displays fatal errors.

  • Level 2 displays fatal errors and warning messages.

  • Level 3 displays fatal errors, warnings, and information messages. This is the default.

  • Level 4 displays level 3 information and key information from different thermal solver routines including convergence traces. The level 4 information is written in the standard output, log file, and the MSGF file.

  • Level 5 displays level 4 information and MPI slave ranks. It also resolves messages by boundary conditions. All extra information from level 5 is written only to the MSGF file.

For levels 4 and 5, you can also request the timing and memory information in thermal solver modules that support it when you include the INCLUDE TIMING INFO IN VERBOSE OUTPUT and INCLUDE MEMORY INFO IN VERBOSE OUTPUT advanced parameters, respectively.
