Hi all,
<div><br>
</div>
<div>I have a query regarding the optimal way of visualising some point data from an experiment & CFD.</div>
<div><br>
</div>
<div>I have several 2D PIV windows from an experiment which have between 100 and 800 points arranged at several x and y locations. In order to compare these against CFD simulations I output the data from the same points in the CFD solver.</div>
<div><br>
</div>
<div>To visualise them I currently use the CSV reader, table to points, and then the Delaunay2D filters to turn this data into 2D slices. </div>
<div><br>
</div>
<div>The problem I have is when I have a gap in the data i.e the shape is not a square but has an empty bit in the middle. The Delaunay 2D filter triangulates all the data and it therefore doesn't constrain to the boundaries of the data.</div>
<div><br>
</div>
<div>I have attached three files which hopefully illustrate my problem.</div>
<div><br>
</div>
<div>I wanted to ask if there is a way to constrain the Delaunay2D filter or use an alternative method to ensure that the shape of the PIV/data window is preserved. I'm sure this type of thing is done fairly regularly but I couldn't figure out how to do this
in Paraview.</div>
<div><br>
</div>
<div>Many thanks,</div>
<div><br>
</div>
