[Latex]利用animate和tikz宏包绘制流程图的动画

[Latex]利用animate和tikz宏包很容易绘制流程图的动画,如下:

%\input{tikz_file/图4-1.tex} %传热学
{\centering
\small
%-----------------------------------------------------------------
 \begin{animateinline}[autoplay,poster=last,  
     begin={%  
			\begin{tikzpicture}[node distance=4mm and 4mm , >=stealth,scale=1,line width=0.2pt,
			place/.style={rounded corners=1mm,rectangle,draw=blue!75,fill=yellow!75,thick,
			inner sep=1pt,minimum width=45mm},
			placeG/.style={rounded corners=1mm,rectangle,draw=blue!75,fill=yellow!75,thick,
			inner sep=1pt,minimum width=25mm},
			post/.style={->,shorten >=1pt,very thick,black}
			] 
			\useasboundingbox(0,0)rectangle(10,7); 
     },  
     end={  
      \end{tikzpicture}  
      },
      timeline=图4-1.timeline 
      ]{2}  
%节点
\coordinate (T) at(4,6.5); %0定义坐标 
\newframe \node[place] (A) at(T) {建立控制方程和定解条件}; %1
\newframe \node[place] (B) [below=of A ] {确定节点(区域离散化)};  %2
\newframe \node[place] (C)  [below=of B ] {建立节点物理量的代数方程}; %3 
\newframe \node[place] (D)  [below=of C ] {设立温度场的迭代初值};  %4
\newframe \node[place] (E)  [below=of D ] {求解代数方程组};  %5
\newframe \node(F)  [below=of E,shape aspect=2.5,rounded corners=1mm,diamond,draw=blue!75,fill=yellow!75,thick,
			inner sep=1pt,minimum width=30mm] {是否收敛?};  %6
\newframe \node[placeG] (G)  [right=of  E] {改进初场};  %7
\newframe \node[place] (H)  [below=of  F] {解的分析};  %8
%绘制箭头

          \draw[->,very thick,black]  (F.east) -|(G.south);  %
          \draw[->,very thick,black] (G.north) |-($(D)!0.5!(E)$);  %
\newframe \node (J) [above,red] at ($(F.east)+(1,0)$){否};  %15
          \draw[->,very thick,red]  (F.east) -|(G.south);  
          \draw[->,very thick,red] (G.north) |-($(D)!0.5!(E)$);           
\newframe \node (I) [right,black] at ($(F.south)!0.5!(H.north)$){是};  %16
          \draw  (F) edge[->,shorten >=1pt,line width =2pt,black](H);%
