I had the same problem a few weeks ago (I'm using hp-FEM). What I did is the following: - create a list of vertices with the coordinates, a global number (identifying the vertex in your internal data structure) and an index (currently empty). Ideally, this is some sort of array with the global number as the index of the array. - write the coordinates into the dx file and update the index of the vertex (indicating the position in the dx file) - loop over all elements and write the connection data to the dx file. Here you need the mapping from the global number of the vertex to the index in the dx file, since you need to write the index. - in the 'field', there is no 'data' component Regards, -- Philipp | work: [EMAIL PROTECTED] +41 1 632 60 38 Frauenfelder | home: [EMAIL PROTECTED] +41 1 862 73 14 [PGP] | http://www.math.ethz.ch/~pfrauenf/ Proudly running Debian GNU/Linux.
