Two lines isolines of a single surface must be frdefem by only one empty row. It can be used with the others flags without problems.

Two empty rows separate two different data sets. The examples are in exampl. But this is how they tell you to do it in the FreeFem manual. Gfem is a language to help you solve Partial Differential Equations in 2 dimensions; it assumes a basic knowledge and understanding of the Finite Maanual Method and of the Operating System used.

Note that you have to recompile almost everything.

Leader of the project, Mac programming, Bug tracking, New developments C. Everything is done for you.

It is strongly recommended to use the configure script. I did not know those commands are not compatible. It will enable the mesh adaptation features in freeFEM.

The actual version of FreeFEM is 3. However one suggests the use of manuap for the GNU Project: It is available at ftp.

Shape optimization with FreeFem++

You should omit export. You must separate two data blocks with one row in order to work with pm3d. In your case this is required, because gnuplot doesn’t support the kind of grid you have for a single surface. We use autoconf and automake in conjunction in order to be as general as possible. A 4×4 matrix would result in 3×3 colored rectangles. But dgrid3d affects all data files of a one splot command.


Janus Gowda 80 1 It guesses the optimization flags according to the compiler. Copy the directory for the application most similar to yours to a new directory. There is an optional flag for configure which enables optimization flags for the compiler: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Mesh adaptation library If you want to compile the mesh adaptation library type: XGfem is a commercial product.

Still you have an irregular grid, which pm3d can’t handle. Could you explain in words, how your plot should look like how are the lines to be displayed?
