Sorry to repost. Does anybody have a feel for whether I can apply a filter and essentially produce a 3d volume mesh with associated scalars and transformed vectors, from it's 2d counter part using vtk?<div><br></div><div>
i.e. a cylindrically symmetric simulation converted to a valid 3d volume mesh. I can apply the filter, similar to this thread:</div><div><br></div><div><a href="http://www.paraview.org/pipermail/paraview/2012-March/024320.html">http://www.paraview.org/pipermail/paraview/2012-March/024320.html</a></div>
<div><br></div><div>but in my case, rather than for presentational purposes, I need the internal of the rotated shell to be a populated volume mesh. Using the method in the above post, or described in my previous post gives only the outer shell.<br>
<div><br></div><div>Any help either way really appreciated!</div><div><br>Cheers,</div><div>Andy<br><br><div class="gmail_quote"><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<div>All,</div><div><br></div><div>I am doing this in code using vtk, but can be reproduced using paraview as noted below.</div><div><br></div><div>I have a 2d mesh which represent a cylindrically symmetric simulation. I want to be able to revolve this around the z-axis to create a 3d mesh. However, when doing this using the rotational extrusion filter, I only seem to have boundary faces. I can't get this to give me 3d cells inside the volume of revolution, which is what I'm after. Can this be done? I have done this in visit and sure enough the mesh is inside the volume of revolution as I expect. </div>
<div><br></div><div>This can be reproduced in paraview using the UCD_00003.inp example from the data set.</div><div><br></div><div>First apply a transform and rotate around 90 degrees round the y axis. Then apply the extract surface filter. I too must do this in my code as the incoming mesh is a vtkUnstructuredGrid and the rotational extrusion filter wants a polydata. Then apply the rotational extrusion filter for 360 degrees with 120 resolution. Finally perform an x-normal slice at the default position. Viewing only the slice shows the outer boundary only, but I had wanted the interior of the boundary to be populated with a mesh, not bothered about its topology, just want a fully populated mesh within the interior. </div>
<div><br></div><div>Again, any help on the above really appreciated?? As I say achieved with visit....which I mention only because I assume the code under the hood would be vtk and hence possible in my case.</div><div><br>
</div><div>Many thanks,</div><div>Andy</div>
