I'm trying to implement discretization of reaction-diffusion PDEs (u_t(x,t) - D^2 u(x,t) = f(u(x,t)), where my unknown (u : R^2 x R -> R^3) is multi-dimensional (not a vector though) and function f (R^3->R^3) is a rational function (P_k/P_l). I'm having trouble with discretizing f(u(x,t)). I'm using getfem 4.2 on Windows, mingw32 (with muparser).
Is there a way to implement discretization of f(u(x,t)) without using internal functions? Basic nonlinear brick supports only a single scalar field variable and low-level generic assembly requires coding non-linear term using getfem++'s internals. I'd use high-level generic assembly from svn trunk's getfem++, but it doesn't ./configure for me (after ./autogen.sh, ./configure has syntax errors in config.status and, after repairing it, missing Makefiles and other files). _______________________________________________ Getfem-users mailing list [email protected] https://mail.gna.org/listinfo/getfem-users
