Hi Everyone,
I am trying to create a mesh around the wing. I have already meshed the wing and farfield domain. However, when I was trying to do assemble the block, I could not do it. In the creating block menu, I can not press "Okay" after selecting all domains. How can I solve this problem? Any help would be appreciated. |

I am still learning how to use Pointwise. I am planning to create O-grid type domain. I have created the wing domain. The wing is meshed with hybrid T-Rex near the leading edge and trailing edge. I also created the hemispherical farfield domain. The mesh type of this domain is unstructured. The block type that I am planning to create is unstructured one. |

Since you're new to PW you're likely not going to use multiple blocks or using a baffle so the first thing to check is that all the connectors are used by 2 and only domains. The way to do this is with Grids > Merge. At the top of this panel is a table. All the connectors should be Manifold and colored cyan in the display. If there are any Free or Non-Manifold connectors you need to merge them together. The totally automated way is Auto Merge. Simply enter a reasonable tolerance (a good guess in your case might be 3 orders of magnitude smaller than the wing's chord length) and click Apply. All the connectors should now be Manifold. If not try increasing the tolerance slightly. Rinse and repeat. Exercise a little caution though because you don't want to use a tolerance large enough to merge away necessary features. If you get to a tolerance that's within an order of magnitude of your surface mesh spacing something else is likely the problem. If that doesn't seem to work or it's not giving the results you want, you might have to post of picture of your mesh. |
