本文摘要(由AI生成):
这段代码包含了两部分:MATLAB和Python脚本。MATLAB部分主要用于控制ABAQUS软件的运行和记录时间成本,同时更新迭代采集步数,并将当前步数写入文件。Python部分则用于处理ABAQUS的输出数据库(ODB)文件,提取特定分析步和节点的数据,包括位移和坐标,然后将这些数据写入文本文件。整个流程从MATLAB脚本开始,通过运行Python脚本来处理ABAQUS的结果数据。
MATLAB启动ABAQUS,提取odb,将ABAQUS模型视作MATLAB的一个函数,用于优化分析
inpName = 'Job-1';
workDir = 'G:\CABLE_CON\TEXT2';
runabaqus(workDir,inpName);
% 运行py脚本文件
system(['abaqus viewer noGui=','out_F.py']);
% 载入数据
t=load('F1.txt');
COOR=load('weizi.txt');
%--------------------------------------------------------------------------------------------------------------
function xx=runabaqus(workDir,inpFile)
MatlabPath=pwd();
cd(workDir);
inputFile=['abaqus job=',inpFile];
system(inputFile);
pause(5);
t0=tic;
cd(MatlabPath);
if (exist([workDir,'\',inpFile,'.lck'],'file')==2)
while exist([workDir,'\',inpFile,'.lck'],'file')==2
t=toc(t0);
h=fix(t/3600);
m=fix(mod(t,3600)/60);
sec=fix(mod(mod(t,3600),60));
pause(1);
fprintf('-ABAQUS calculating-\n time costed %d:%d:%d\n',h,m,sec);
end
fprintf('---------ABAQUS complete---------\n time costed %d:%d:%d\n',h,m,sec);
xx=1;
else
fprintf('\n runabaqus error:InpFile submmit failed\n');
xx=0;
end
end
更新迭代采集步数的程序代码

将当前步数写到cycle.txt 文件下
f=open('cycle.txt','r')
n=f.read()
f.close()
读取odb文件
odb = openOdb(path=r'G:\CABLE_CON\TEXT2\Job-' n '.odb')
取odb文件中最后一个分析步进行数据提取
Step_1=odb.steps['Step-' n]
region = Step_1.historyRegions['Element ASSEMBLY.1']
xy1=region.historyOutputs['CTF1'].data[300]
s=str(xy1)
s = s.replace("(", "")
s = s.replace(")", "")
disFile=open('F1.txt','w')
disFile.write(s)
disFile.close()
lastFrame=Step_1.frames[-1]
Zuobiao=lastFrame.fieldOutputs['COORD']
Regioncare=odb.rootAssembly.nodeSets['RP']

total=Zuobiao_x,Zuobiao_y,Zuobiao_z,Zhuanjiao_x,Zhuanjiao_y,Zhuanjiao_z
s1=str(total)
s1 = s1.replace("(", "")
s1 = s1.replace(")", "")
disFile=open('weizi.txt','w')
disFile.write(s1)
disFile.close()
# 运行python脚本文件
