Time Problem TOUGH2 with EOS7R

Hello everyone,
I’m a new TOUGH2 user. I am trying to simulate a diffusive transport of nuclides in porous media. The input works and I get good results. But I still have a problem with the PARAM-input-parameter. I want to simulate a 'long-term' analysis (round about 100 years, every timestep one year), but the simulation always stops after one year. There is no error-message. I have the same problem, if I change the input to: whole time: 10 years, timestep: one year.

I hope someone could help me. Thank you very much. 
Maike

    Hi Maike,

    Also I am a  new TOUH2 user. You solved your problem?

    I think it's because the convergence is achieved on the first iteration and  the steady state has been reached.

    It is possible that the timestep is too small.

    Hi Maike,

    I think Barbara is on the right track, but there is no way of telling without seeing the output file, which almost certainly has a message indicating why the simulation stopped. So please: look carefully at the output file and provide that information, so the TOUGH community can help you resolve the issue.

    Regards,

    Stefan

    Thank you for your reply. I solved the problem. It was a problem with the convergence.

    Best regards,

    Maike
