前段时间找了点Matlab与ANSYS协同工作的资料，在我看来所谓协同是ANSYS将结果写到文件然后Matlab读，或者Matlab写数据到文件ANSYS读，协同是通过读写文件实现的。我找了个瞬态分析的例子，写了APDL，将网上找到的ANSYS结果输出部分代码加了进来，实现三个节点位移时间数据写到文件，然后Matlab读取该文件并作三节点位移-时间图。说明一下：ANSYS生成的文件都在Matlab当前工作目录下。
1 Matlab的代码（mat2ans.m）
!“D:\Program Files (x86)\Ansys Inc\v100\ANSYS\bin\intel\ansys100.exe” -b -i “E:\WP\m2a\transient.mac” -o “E:\WP\m2a\ans.out”
%save(‘E:\WP\m2a\matdat.dat’,‘data’,’-ascii’)
%load(’-ascii’,‘E:\WP\m2a\ans.rst’)
load ‘result1.txt’
t=result1(:,1);
u1=result1(:,2)*1e3;
u2=result1(:,3)*1e3;
u3=result1(:,4)*1e3;
plot(t,u1,‘k’,t,u2,‘c’,t,u3,‘g’)
legend(‘Node 100’,‘Node 146’,‘Node 200’)
xlabel(‘time/s’),ylabel(‘disp/mm’)

3 运行过程概括
执行Matlab的mat2ans.m，由于第一条命令启动ANSYS，控制权由Matlab交给ANSYS，ANSYS以批处理执行transient.mac的APDL代码，并生成想要的结果文件result1.txt然后自动退出，Matlab得到控制权接着执行余下的命令。
