FEATool Multiphysics VirtualBox VM Available
FEATool Multiphysics is now available as a VirtualBox Virtual Machine (VM) disk image to quickly get up and running and for easy installation on systems that...
can in FEATool simply be written as
u' - D*(ux_x + uy_y) = 1
The parser will process this equation string and decompose it into the constituents of the finite element weak formulation which is used by the assembly and solver routines. Moreover, other physics modes can similarly be changed to accommodate custom additions to the pre-defined equations.
An example showing how to implement a custom equation model, solving a Black-Scholes example equation for financial derivative modeling, can found in the Tutorial section of the FEATool Users Guide
