preCICE mesh id (-1) error (OpenFOAM+CalculiX CHT)

ok, so you just changed this line in the condfig reader, and which yaml-config did you use then?

@mattfrei I tried to search for the directory with this case and the config.yml, but couldnā€™t find it.
I cannot remember what exactly I used, but it is something similar to the previous reply.
I was able to use the modified faces-mesh and nodes-mesh for different data fields.

Sorry couldnā€™t help more.
