  1. How to create design and non design geometry

    Hi, I am trying to optimize the design of a control arm of suspension system. For that reason i have modeled the design in NX and exported in IGES format for HW-Hypermesh. Now for my optimization i am concerned with topology optimization of the yellow(design region) part of the arm. The green (non design) region is not to be optimized as per my design requirements. I used the organize command to move the design volume to design component and other to non design component, but while creating a mesh i am having issues. When i mesh the non design region using 2D mesh it got successful (non design mesh.png) after that i make design component as current and mesh it volume tetra mesh 3D, but it is meshing the complete part including nondesign space (design space mesh.png) Kindly check the issue.png about what i am saying. Please assist me in solving it and also once the meshing is done how to combine the design mesh and non design mesh so as in analysis and optimization it should behave as a single unit? The .hm file can be accessed from this link( https://www.dropbox.com/s/pujyaajiumo6zx9/suspension_arm.hm?dl=0) Thank you
  2. Hello, I tried to simulate the Frontwing of our Formula Student car. I generated a proper Mesh (as you see in the Dropbox link). However Virtual Wind Tunnel is not calculating even if the Mesh was generated and i have no intersections. Is there a Problem with positioning or refinement zones? (VWT Report also in the Dropbox) https://www.dropbox.com/sh/pui9dgpk2oed0lr/AADiZajnV8nUKi9monsQVkjra?dl=0
