I got a questions regarding the mesh generation in ANSYS Mechanical. I am running an acoustic calculation where I got boundary conditions applied to faces specified with B and A/C. In order to analyze the acoustic transmission and so forth the body is split up into three parts creating two inner faces.December 8, 2020 at 1:50 ampeteroznewmanSubscribernIn SpaceClaim, if you have a three cylindrical bodies that have two coincident faces at each end, you can go to the Workbench tab and click the Share button. That will remove one of the two coincident faces at each end. Now when you bring that geometry into Mechanical, no automatically generated contacts would be made, and if there are, you can delete them from the Connections folder.nThere are still three bodies to mesh, but the nodes on the face between them are shared between the adjacent bodies. When you write out this mesh, it will not have CONTA174 and TARGE170 elements.nIf you look at the mesh, the front body was meshed with Tet elements, while the other body was meshed with Hex elements. In both cases, they are quadratic elements.nIn ANSYS Help, Mechanical APDL, Element Library, you can see the description of a FLUID221 is a quadratic Tet element while a FLUID220 is a quadratic Hex element. In Mechanical, right click on Mesh and Show Sweepable Bodies. If they all highlight green, then you should add a Mesh Method of Sweep on the front body and it will mesh with Hex elements. In that way, you can get all the elements to be FLUID220.nDecember 9, 2020 at 2:44 pmJanD3004SubscriberThe problem is solved.nThanks a lot nViewing 2 reply threads
