Does precice work with 2D problem?

Anyone konws that if precice works with 2D problem?

The dummy solver works well initially, but if I change the dimensions from 3 to 2 in the precice-config.xml, it did not work. Anyone konws why?

This is the only line I changed in precice-config.xml.

preCICE works fine in 2D as well in 3D (normally). Could you tell us about the error message that you get and also a bit more about your setup? What codes do you couple? Do you use some preCICE adapters and how do the solver logfiles and the preCICE configuration look like?
