Post as a guest Name. I thought pm3d would include the colored pattern of heat intensity in the bottom of the plot. X programming, Bug tracking, New developments, Web maintainer and lots of other minor things. It can be used with the others flags without problems.

This utility is available at several ftp sites in France or in the USA. FreeFEM is an implementation of the Gfem language dedicated to the finite element method. I did not know those commands are not compatible.

It is much easier and should be platform independentyou don’t have to know anything about your system. The examples are in exampl. The home page of FreeFEM is http: Gfem is a language to help you solve Partial Differential Freefen in 2 dimensions; it assumes a basic knowledge and understanding of the Finite Element Method and of the Operating System used. As you have it, the options don’t fit together. Janus Gowda 80 1 You must separate two data blocks with one row in order to mabual with pm3d.


A 4×4 matrix would result in 3×3 colored rectangles.

Modify the files as needed. Also I don’t find the way to fill with solid mxnual the gaps between the lines in the plot. It plots fine but I think pm3d is not doing anything. Two lines isolines of a single surface must be separated by only one empty row. The actual version of FreeFEM is 3. Could you explain in words, how your plot should look like how are the lines to be displayed? However one suggests the use of make for the GNU Project: It is available at ftp.

Two empty rows separate two different data sets. You need to add one point twice, because pm3d uses four points to create one rectangle with one color.

XGfem is a commercial product. An answer to this requires first a proper explanation of different possibilities to organize the data: Email Required, but never shown.

The following script shows how it could work, but as I don’t have the full data set and don’t know how dgrid3d copes with that many data sets see 1.

It guesses the optimization flags according to the compiler. Inside gnuplot you can use dgrid3d to freefen your input data to get a regular grid and plot that one with pm3d. A very small example of what you can do: Quite complicated problems and systems of equations can be solved also.

But dgrid3d affects all data files of a one splot command. Note that you have to recompile almost everything. It will enable the mesh adaptation features in freeFEM. So fresfem also need multiplot to use two splot commands.

Without the configure script edit the makefile. There is an maanual flag for configure which enables optimization flags for the compiler: Everything is done for you.
