I have a request related to cell geometry for FVM. I am<br>
working on implementing a solver for coupled electron hole transport<br>
problem in a semiconductor.<br>
<br>
For the descretization (see the link [1] below), i want to use the FVM<br>
which uses voronoi box around each node as the control volume. Current<br>
implementation of the ComputeCellGeometry, provide the centroid of the<br>
cell.<br>
<br>
Can i request for functionality similar to ComputeCellGeometry, which<br>
on call returns, the orthocenter and the area perpendiclar to each<br>
edge for flux computation ?<br></blockquote><div><br></div><div>1) I had to lookup orthocenter and I got this: <a href="http://www.mathopenref.com/triangleorthocenter.html">http://www.mathopenref.com/triangleorthocenter.html</a></div>
<div> which only defines it in 2D, and says it can be outside the triangle. This does not sound promising.</div><div> If you explain the calculation to me, I can help you implement it.</div><div><br></div><div>2) I do give back the edge area if you pass in the edge.

Or any suggested references to look for geometry related routines.<br>
