Difficulty to obtain a conformal mesh

      Hello everybody,


      I am trying to mesh a complex geometry for a steady-state electrical simulation. I mesh the domain with Fluent using quadratic element. I also added a Patch Conforming method using tetrahedrons.

      After reading different topics about conformal mesh, I opened my geometry on DesignModeler, and put all bodies into a single part (since I have different materials).

      The mesh is conformal for every bodies, except one, and I can't explain why. With previous and similar geometry this problem did not occur. I tried setting the Topology to Share in SpaceClaim without success.

      On the picture below (element looks very bad but it is because I took the screenshot in a section plane in order to detect the issue) the cold-green long body is not conformal with the rest. On the other hand the grey, orange and blue bodies are OK.

      Do you have any idea how to solve this ?

      Sharetopo may fail if there are geometry errors. Please check geometry in SpaceClaim. Select geometry in structure tree --> Use right click --> Select Check Geometry. The geometry should be error free to proceed. If geometry has any errors, please modify/recreate geometry at those places.nTo make share topo successful, you may need to think of any geometry modification. Please check if you can use DesignModeler or SpaceClaim. Both has sharetopo. nnhttps://www.youtube.com/watch?v=h43E1YO1LiMnnRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn

      Thanks for your answer. nI checked the geometry (no problem found), and used a shared topology tools (as shown on the video) but the issue is not resolved. nI found half a solution: I redid the geometry from the beginning, and it worked well. But with a geometry that presents this issue, I haven't found a way to correct it yet. n
