[Mesa-users] Problems when running MESA program

Thu Feb 24 08:37:05 UTC 2022

Greetings,

Firstly, I appreciate the wonderful program you provided to all of us, but I've met some problems running MESA.

MESA version: r15140
MESASDK version: x86_64-macos-21.11.1
Computer info: MacBook Pro (13-inch, 2019, Four Thunderbolt 3 ports)
OS: macOS 10.15.7 (Catalina)

I believe that installation is successful, with all enviroment variables set properly. Then I copied the /star/work folder to a new place and made with ./mk then ran with ./rn , the output was a little different from what was expected:

 The terminal output contains the following information

      'step' is the number of steps since the start of the run,

      'lg_Tcntr' is log10 center temperature (K),

      'lg_Dcntr' is log10 center density (g/cm^3),

 All this and more are saved in the LOGS directory during the run.

Then the program stuck with no further output, and it never stopped running after that. I'm not sure what does "max decrease" mean. I'll be thankful if you could provide any help.

Thank you.
