Besides, I have a boundary condition file `abc.xyz.fvbnd` in FieldView 1.3 format which was generated by grid pre-processor. </div><div><br></div><div>My problem is: How to extract the surface of the aircraft?</div><div><br></div><div>Because the Plot3D format is a multi-block curvilinear grid. When I use `Extract Surface` filter, it will extract the block interfaces. My current solution to combine blocks by `Merge Blocks` filter. Then I can extract the surfaces, including the outer boundary and the inner aircraft walls. After that, I need to clip the farfield and keep the aircraft walls. Is there a better solution?</div><div><br></div><div>However, what I need to do is to evaluate the force on specific parts. So I need to use the information from the boundary condition file `abc.xyz.fvbnd` which indicates ranges of indexes in curvilinear grid as wall of certain parts. My problem is how to use it to generate several surfaces in paraview for rendering and integration.</div><div><br></div><div><br></div><div>p.s. I am using paraview 5.4.1. The grid consists of farfield outer boundary and several aircraft parts' wall inner boundaries.</div><div><br></div><div><br><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">Di Cheng</span><div style="line-height:21px" data-mce-style="line-height: 21px;"><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">Engineer of Research Center</span></div><div style="line-height:21px" data-mce-style="line-height: 21px;"><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">China Academy of Aerospace Aerodynamics</span></div><div style="line-height:21px" data-mce-style="line-height: 21px;"><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">Phone: +86-l58Ol5949ll</span></div><div style="line-height:21px" data-mce-style="line-height: 21px;"><p style="line-height:1.7;padding:0px;margin:0px;font-stretch:normal" data-mce-style="line-height: 1.7; padding: 0px; margin: 0px; font-stretch: normal;"><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">Address: No.17, YunGang West Road, Fengtai District, Beijing, China</span></p><p style="line-height:1.7;padding:0px;margin:0px;font-stretch:normal" data-mce-style="line-height: 1.7; padding: 0px; margin: 0px; font-stretch: normal;"><span data-mce-style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" style="line-height: 1.5; color: #000000; font-family: arial,helvetica,sans-serif; font-size: xx-small;" color="#000000" face="arial, helvetica, sans-serif">Zip Code：100074</span></p></div></div></div></div></div></div></div><br>_______________________________________________<br>Powered by www.kitware.com<br><div><br></div>Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html<br><div><br></div>Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView<br><div><br></div>Search the list archives at: http://markmail.org/search/?q=ParaView<br><div><br></div>Follow this link to subscribe/unsubscribe:<br>http://public.kitware.com/mailman/listinfo/paraview<br></blockquote><div><br></div></div></body></html>
