 August 13, 2010, 13:16 How to generate 3d Wire Screen #1 New Member   Join Date: Jun 2010 Posts: 10 Rep Power: 8 Hello Everyone, can anyone help me how to create a 3D thin wire screen (see attached picture) ? I want to make stacked multiple wire screens. Fluid will flow through the open space and in the end i am going to study temperature profiles on the wire screen due to the heat transfer from the fluid. Any help, how to draw this kind of screen (see attached picture) in gambit or any other CAD softwares?Plain-Wire-Mesh-Screen.jpg Thanks.. MM

As a numerical simulation method, CFD model need to use a mesh with a adequate resolution, the minimum requirement is that 5 cells for the worst across any flow passage, 10 is preferable, in rather that the passage in the stack is very complex. In a word, to simulate the flow in a stack of wire screen directly is a challenging task for any CFD system.
