Theofilos, These may not be the most elegant solutions, but they are simple and will work very nicely. ParaView is capable of reading multiple datum sets and displaying the results either in the same window or in side-by-side windows (and, probably both scenarios at the same time). (1) Write out two separate results datum sets that are independently displayable. The first results datum set with mid-edge nodal points but without pressure at the vertex nodal points, and the second results datum set without the mid-edge nodal points but with pressure at the vertex nodal points. (2) When writing out a results datum set, generate a pressure at the mid-edge nodal points by averaging the pressure found at the edge's end-points. (3) Suggestion #2 can be extended. Since ParaView, at a fundamental level, was designed to display either "centered" cell-values and point-values, and you very likely have 20-node quadratic(?) hexahedrons with cell-values "centered" at a 2x2x2 Gaussian quadrature in which you are interested in seeing results, a painless way to get a single, simple displayable results datum set is, at the time you write out a given 20-node brick, break the 20-node quadratic brick and its cell data into eight 8-node linear bricks. (A similar effort is required when writing out point coordinates and point values.) When you get to ParaView, there will be no visual confusion as to which Gauss point result is located where in the finite element. While the display is not quadratic in its rendering, eight linear bricks for each quadratic brick is a pretty decent representation. It will get you started using ParaView. Quite possibly someone else can explain how ParaView renders quadratic data and elements. Samuel Key FMA Development, LLC 1005 39th Ave NE Great Falls, Montana 59404 On 12/9/2014 7:55 AM, Teo Ioannis
