Non-Conformal Structured Meshing Via Directed Mesher

Hello,
I am trying to create a 2D structured mesh for an aerospike nozzle on STAR CCM+ and so far am using a patch mesh through the Directed Mesh tool with Badge for 2D meshing. However, when selecting the patches in the streamwise direction (purple lines), I cannot find a way to create non-conformal boundaries between the patches, meaning that the mesh is far too fine in the region of quiescent air (bottom of image). I have attached an image of the domain in the patch mesher. The purple lines clearly show that if i wish to refine the mesh in the streamwise direction in the nozzle, this will occur uniformly in the entire y direction. Is it possible to create a non-conformal structured mesh where the cell faces touching at either side of the purple lines do not match up? Thanks, Chris Capture_Forum.PNG |

Also - keep in mind that Directed Mesher is a buggy piece of ***; once you change any size of any part even by 1 mm - it will delete all your patches and settings wailing that ".. topology has changed ...". |

Thank you for your answer. To create this separate Directed Mesh Operation, am I right in saying I would need to create two separate parts and mesh them separately, then, create a boundary to join them?
