Problem running TOUGHREACT in Petrasim


I am new to TOUGHREACT. I set up a simulation with material properties and other parameters. Created MESH. However, TOUGHREACT Halts Simulation prematurely with an error message "MESHMAKER HAS READ UNKNOWN BLOCK ALBEL REACT .. SIMULATION HALTED PREMATURELY.

Shall greatly appreciate help to understand where I might have gone wrong.

Thanks in advance.

  • Hi,

    This is a Petrasim issue, since TOUGHREACT (and TOUGH2) will not quit because of an unknown keyword block. You may have put the REACT block too close to the end of MESHM, so move it above the MESHM keyword, and make sure you leave a few blank lines after the MESHM entries, since it looks for blank lines to know it is done. 



  • Thank you very much Eric. I am currently setting up a simulation for modeling quartz vein formation and there are some issues which I am trying to understand. Shall get back to you for help.

    I do not know which part of the world you are in - hope you are safe and healthy. We in India are under total lockdown.
