I wonder if you have considered providing an option to reduce the footprint of the simulation run output. For instance, showing completion percentage, or a progress bar (similar to JutulDarcy), instead of printing the output at each time step.

Consider the case where you need to run hundreds of simulations in parallel; printing out the status of each simulation not only will clutter the screen quickly, but also, in my experience, it may slow down computation time.

Dear Oscar,

There is a verbose flag that can be set to false in the models inheriting from `PhysicalModel`.    You might also try running the line mrstVerbose false on our Matlab command line.   Does that help?

Best regards,
Odd A.
