FEATool Multiphysics - Version 1.5
FEATool is designed to be a very easy to use PDE and FEM Multiphysics Simulation Toolbox for MATLAB. This release brings the following major features and improvements
New 3D geometry engine
The implicit 3D geometry CAD engine has been redesigned now taking geometrical features into account which results in much improved 3D geometry, grid generation, and post processing
External function calls for equation and boundary coefficients
Write your own MATLAB m-script coefficient functions and call them directly from the FEATool GUI. For example, a function call such as
2.5*my_fun(u,x,y)^2can be used directly in the FEATool PDE equation and boundary coefficients. Which will search for and call the local m-file my_fun.m during the FEM assembly and evaluation operations.
Generalized Navier-Stokes slip boundary conditions
Fluid flow problems with curved and non-axis aligned boundaries now also supports slip boundary conditions (zero velocity in the normal direction)
General GUI usability improvements
GUI menu support for grid conversion and smoothing allowing convenient conversion between triangular, quadrilateral, tetrahedral, and hexahedral grid cells
GUI stability improvements such as interruptible waitbars for grid generation and solvers, bug fixes and more
