  1. CFD TetraMesh Issue

    Hi all, I am trying to create a simple CFD tetramesh in a pipe. When I try and run the Acusolve solution, I get the error "No Valid 3D element found in the neighbourhood of a trai element". The resulting error shows "Exterior Trias" and "External Quads" and show voids in the boundary layer mesh at random mesh locations. Can anyone help me with this issue? The Pipe inflows and outflows are set as W/O BL float and the Wall is set as With BL Fixed. Cheers, James
  2. Hello, I am trying to use TCL code to automate the tetrameshing process due to a large number of individual components needed to be meshed for CFD. I am using a simple right angled pipe and have a variation of code that was given in the "Hyperworks Desktop Reference Guide". I can successfully use the tetramesh process within Hypermesh itself manually, selecting my "Wall" as With BL (Fixed) and my "Inflow" and "Outflow" as W/o BL (Float) and do not have the issues that I will explain. However, when I try and automate the process using TCL code, my "^CFD_trias_for_tetramesh" part is only a 2D mesh. This then results in the following failure when using the AcuSolve job launcher: "No Valid 3D element found in the neighbourhood of a tria element". Whereas, if I was to do this manually, the part would be called "CFD_tetcore001", however it would be a 3D volume mesh. Here is my code: *createstringarray 2 "tet: 21532 1.2 2 0 0.8 0 0" "cfd: 86 0.0035 22 1.2 1" *createmark comps 2 "Inflow" "Outflow" *createmark comps 1 "Wall" *tetmesh comps 2 0 comps 1 3 1 2 Would anyone be able to provide any suggestions as to how to get a 3D mesh in the centre of the fluid. Thanks, James
