Hi there, 1). I am trying to do the solution interpolation from the vertex to the cell. For a 2-D problem, it is interpolating 4 values on vertices to 1 value for the cell. However, I only find DoFTools::distribute_cell_to_dof_vector, which project cell value to vertex values. Is there any function I can use for global interpolation from vertex to cell? Which step gives an example for this?
2). I am using cell->measure() to get the cell volume for a 3-D problem. If I also want the six face areas for this cell, what can I do? Is there any example? -- Dr. Nan Zhang Postdoctoral Research Associate Department of Geological Science Brown University 324 Brook Street Box 1846 Providence, RI 02912 HomePage: http://www.geo.brown.edu/People/Postdocs/Zhang/NanZhangHome.html
