Hi. I'm Architect who is learning about wind phenomena around buildings.<br>
I've already run a wind simulation with OpenFoam using ODS-Studio and<br>
I had some beautiful visualization with Paraview<br>
My question is about how to visualise isocurves of shelter parameter<br>
around the model like the picture (Fig.2) in this paper:<br>
<a href="http://i.imgur.com/OmUXWWj.png" target="_blank">http://i.imgur.com/OmUXWWj.png</a><br>
<br>
The paper is by Wisse, J. A. A Philosophy for Teaching Wind in the<br>
Built Environment Energy and Buildings, 1988, 11, 157-161<br>
<a href="http://www.sciencedirect.com/science...78778888900321" target="_blank">http://www.sciencedirect.com/science...78778888900321</a><br>
<br>
I would like to visualise similar isocurves representing the ratio of<br>
wind speed around the model to the input wind speed. I don't have<br>
clear idea how Paraview shows isocurves or isosurfaces in my<br>
simulation. Apparently, it shows pressure, but I like areas showing a<br>
ratio of speed.<br>
Is it possible to set up Paraview for this kind of visualisation? I<br>
don't know if my question makes sense (my English is second language).<br>
<br>
Regards<br>
