Optimization of geometry for combustion with mesh interfaces

  Hi
  
  I am trying to optimize the geometry of a combustion chamber to maximize combustion efficiency. It is a conjugate problem and therefore has domain interfaces . I have made a length of the geometry a parameter. When I try to change this parameter in the parameter section on workbench, and update the solution, the mesh interfaces are deleted (they are unmatched) causing errors. The length that is a parameter is on the interface.

  Have you labelled the interface zones (surfaces) with "interface" as part of the boundary name? Which solver are you working with?

  No. However I have changed there type to 'interface' and match them, this is undo when I reload the set up. I'll rename them now to see if it helps. Pressure based ,absolute, steady, axisymmetric.
  
  Thanks for the help
