STRESS output from Abaqus to Matlab (Record key 11)
In this example a simple Abaqus model is analysed and results are retrieved by postprocessing the results *.fil file generated by Abaqus using Matlab. For more information please see the Documentation of Abaqus2Matlab toolbox.
Contents
Run Abaqus model
Change current directory to Abaqus working directory
a = strfind(S,'\');
cd(S(1:a(end)-1))
Copy the input file to be run by Abaqus into the Abaqus working directory
copyfile([S,'\AbaqusInputFiles\11.inp'],[S(1:a(end)-1),'\11.inp'],'f')
Run the input file 11.inp with Abaqus
!abaqus job=11
Pause Matlab execution to give Abaqus enough time to create the lck file
pause(10)
If the lck file exists then halt Matlab execution
while exist('11.lck','file')==2 pause(0.1) end
Postprocess Abaqus results file with Matlab
Assign all lines of the fil file in an one-row string (after Abaqus analysis terminates)
Rec = Fil2str('11.fil');
Obtain the desired output data
out = Rec11(Rec)
out = 1.0e-03 * Columns 1 through 3 0.950879300944507 -0.950879300944507 -0.000000000000000 -0.950879300944507 0.950879300944507 -0.000000000000000 0.950879300944507 -0.950879300944507 -0.000000000000000 -0.950879300944507 0.950879300944507 -0.000000000000000 Column 4 -0.950879300944507 -0.950879300944507 0.950879300944507 0.950879300944507
Verify output
Check number of attributes
nAttr=size(out,2)
nAttr = 4
Check the number of entries
nEntr=size(out,1)
nEntr = 4
Check class of output
cOut=class(out)
cOut = double
