matlab求解热传导实例(共3页).doc

精选优质文档-倾情为你奉上matlab求解热传导问题的几个例子1.金属板导热问题p,e,t=initmesh(crackg);u=parabolic(0,0:0.5:5,crackb,p,e,t,1,0,0,1);pdeplot(p,e,t,xydata,u(:,11),mesh,off,colormap,hot);解:2.Matlab自带例子:p,e,t=initmesh(squareg); p,e,t=refinemesh(squareg,p,e,t); u0=zeros(size(p,2),1); ix=find(sqrt(p(1,:).2+p(2,:).2)0.4); u0(ix)=ones(size(ix); tlist=linspace(0,0.1,20); u1=parabolic(u0,tlist,squareb1,p,e,t,1,0,1,1);pdeplot(p,e,t,xydata,u1(:,20),mesh,
