I want to create a mesh on a thin body, a rectangular duct with a flap, and an acoustic cavity around it. The objective is to map the pressure fluctuations obtained from Fluent to the inner side of the duct.<\/p>\n

<\/p>\n

 <\/p>\n

The rectangular duct has a thickness of 1mm i want to mesh it with SOLSH190 elements.<\/p>\n

<\/p>\n

I have devided the acoustic cavity to sweppable bodies to create structured mesh.<\/p>\n

Explained all, I am not able to create a mesh on this gemoetry due to various errors:<\/p>\n

    \n
  1. A mesh could not be generated using the current meshing options and settings.<\/li>\n
  2. Thin model sweeping failed to mesh the side areas. The surfaces are generally very narrow. Using hard edge size controls on edges to force the same number of divisions might be helpful.<\/li>\n<\/ol>\n

    <\/p>\n

    <\/p>\n

     <\/p>\n

    I am not sure what i am doing wrong…<\/p>\n
