Inhomogeneous Heat Equation on a Square Domain This sample assignment shows how to solve the heat equations with a source term using the parabolic function in the Partial Differential Equation Toolbox™. The specific heat equation is Generate Mesh [p,e,t]=initmesh(g); figure; pdemesh(p,e,t); axis equal
2. 2. Generate Initial Conditions The discontinuous initial value is 1 inside the circle of radius 0.4 and zero outside. u0=zeros(size(p,2),1); ix=find(sqrt(p(1,:).^2+p(2,:).^2)<0.4); u0(ix)=ones(size(ix)); Generate Time Discretization We want the solution at 20 points in time between 0 and 0.1. nframes=20; tlist=linspace(0,0.1,nframes); Find FEM Solution u1=parabolic(u0,tlist,b,p,e,t,c,a,f,d); 75 successful steps 1 failed attempts 154 function evaluations 1 partial derivatives 17 LU decompositions 153 solutions of linear systems Plot FEM Solution To speed up the plotting, we interpolate to a rectangular grid. figure; set(gcf,'Renderer','zbuffer'); newplot; colormap(cool); x=linspace(-1,1,31);y=x; [~,tn,a2,a3]=tri2grid(p,t,u0,x,y); umax=max(max(u1)); umin=min(min(u1)); for j=1:nframes, u=tri2grid(p,t,u1(:,j),tn,a2,a3);i=find(isnan(u));u(i)=zeros(size(i)); surf(x,y,u);caxis([umin umax]); axis([-1 1 -1 1 0 1]); shading interp; Mv(j) = getframe; end
