Hello,<br>
I wonder if there exists any VTK class to do the job or at least part of it, such as computing the tensor field for instance. My steady flow dataset consists of an unstructured grid with various scalar and flow associated PointData. If I could save some coding time and avoid reinventing the wheel, it would be great.<br>
Thanks in advance for your help.<br>
<br>
Stan<br>
