Thanks for your answer, I made some comments and clarified my questions (see below) Sincerely, Anis Le 24/02/2011 11:47, c. a écrit : Hi, Please also keep the list in CC so the answers will be available for other users who search the archives On 24 Feb 2011, at 10:34, Anis Djedidi wrote: Dear Carlo, First of all, thank you for your help. I have some other questions about the simulation: Is there an easy way to plot the different variables (n, p, V, currents, geometry, ...) ? Yes, you can use the functions from the package FPL to either - export data to VTK format and visualize it with paraview ('fpl_vtk_save_field') - plot it directly in Octave ('pdemesh' and 'pdesurf') if you use the gnuplot graphics toolkit I recommend the first approach as the second might become very slow, with the fltk graphics toolkit it is OK though. In the secs2d package, there is the function Updesurf, is it obsolete? I noticed that Open DX and gmsh are used? How could they be "connected" to Octave? OpenDX is somewhat obsolete, the fpl package still has wrappers for it for backward compatibility, but I suggest using paraview instead. Wrappers for Gmsh are in the 'msh' package How could we change the geometry? in the example I sent you there is an example about creating a geometry. Is there any constraint on the geometry that I could use? I don't understand this question. I joined a pdf showing the type of geometry i need to simulate, is it possible to do it with this package? The p-region is limited in the two directions (that is what i mean by "constraint") in the function PNDIODE, there is a variable named pow, What is its role? same thing for the doping profile ? same answer Is the bim package compatible with matlab? no, it uses a lot of octave-only syntax constructs, I think it would be a PITA to convert it. Sorry, but I did not understand the _expression_ a PITA Again, thank you for your help, and we would be pleased if we collaborate.
