Hi,

I'm trying to implement the changeDictionary function to edit my boundary for a gmsh generated mesh.

However even though I can run "changeDictionary -constant" successfully, nothing changes in my files and upon trying to run the solver i get an error due to boundary cast (e.g. "--> FOAM FATAL ERROR: Attempt to cast type patch to type lduInterface")

Do i need to implement any changes in my controlDict?

Info:
Solver: SRFPimpleFoam, but have tried SimpleFoam as well
Changes attempted: 2 patches changed from "patch" to "cyclic", one to "wall"

system/changeDictionaryDict:
Code:
