IIRC this should only be one additional term in the fluid equations, meaning a one-liner. Could be easier to add a parameter for this.

Try to merge the develop branch into your branch https://github.com/richahert/tutorials/tree/aste. Then, the changes here should be easier to overlook. What is your overall plan, to create a new tutorial ASTE-OpenFOAM...

The tutorial only works with the latest Nutils release, v6. For Nutils develop (v7), the tutorial needs some updating. ``` python3 -m pip install --user https://github.com/evalf/nutils/archive/master.zip ```

Some comment @gertjanvanzwieten wrote to me a while back > Actually, in master we extended to solver methods to accept multiple targets & residuals, which means we don't have to...

Let's document which tutorials version requires which Nutils version on https://precice.org/adapter-nutils.html

Any help would be much appreciated :hugs: Relevant codes are: - partitioned heat conduction: [heat.py](https://github.com/precice/tutorials/blob/develop/partitioned-heat-conduction/nutils/heat.py) - flow over heated plate: [solid.py](https://github.com/precice/tutorials/blob/develop/flow-over-heated-plate/solid-nutils/solid.py) - perpendicular flap: [fluid.py](https://github.com/precice/tutorials/blob/develop/perpendicular-flap/fluid-nutils/fluid.py)

I think the two different verbosity levels `debug` and `release` are enough already. But a good additional feature would be the option to switch off debug statements at runtime and...

Per timestep, we still have ``` diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 PIMPLE: iteration 1 DILUPBiCGStab: Solving for Ux, Initial residual...

Just discussed with @MakisH, we agree that * we make the logger level configurable at runtime * set it to "info" by default
