Hi i would like to ask regarding shared topology as I am having some issues with my nodes not merged. from my understanding shared topology with automatic method will automatic result in nodes from co-planar contacting body surfaces being merged when meshing. however,for my case, the nodes do not seem to merge at the interface of these bodies.<\/p>\n

<\/p>\n

Also as I am using the student version of ansys workbench, I would like to get a a hexa mesh as opposed to a tetrahedral mesh. I also need inflation to capture BL effects within the hose and nozzle. I split my part into three parts so that I am able to define multizone for both the cylindrical parts. as for the nozzle area with slightly more complex geometry, I am unable to define a multizone mesh as i get the following errors. Is there any other approach I can take to acheive a hexahedral mesh throughout with an inflation layer throughout the walls of the pipe.<\/p>\n
