Local mesh refinment in Ansys Maxwell

      Hello everybody,


      I am working with Ansys Maxwell 3D and try to refine mesh in certain areas of my body. To be more specific: I have created a cylinder and now I want to refine the mesh in a thin disc inside this cylinder. I tried to split the body along the face of this disc but I dont really get the right boundary/ matching conditions on this faces.


      Does anyone has an idea how to get a proper solution?


      Many thanks in advance!

      In order to refine the mesh on a plane cutting thru an existing volume, first create a coordinate system at the desired cutplane.  Then, use Modeler > Surface > Section to create a perfect cross-sectional sheet for the body. Select the newly created sheet (in history tree or by clicking on it) and apply a mesh operation "On Selection".


      If the initial body consists of separate materials and must be split into two objects, first create a coordinate system at the desired cutplane. Then, use Modeler > Boolean > Split to divide the body in half. Use Edit > Selection Mode > Faces to choose one of the end faces at the split location and apply a mesh operation "On Selection".  Adding an extra 2D sheet object between two touching objects is not recommended since it is redundant and adds unnecessary complexity to the model.
