NODE DEFINITION output from Abaqus to Matlab (Record key 1901)
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\1901.inp'],[S(1:a(end)-1),'\1901.inp'],'f')
Run the input file 1901.inp with Abaqus
!abaqus job=1901
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('1901.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('1901.fil');
Obtain the desired output data
out = Rec1901(Rec)
out = 1.0e+02 * Columns 1 through 3 0.010000000000000 7.200000000000000 3.600000000000000 0.020000000000000 7.200000000000000 0 0.030000000000000 3.600000000000000 3.600000000000000 0.040000000000000 3.600000000000000 0 0.050000000000000 0 3.600000000000000 0.060000000000000 0 0 Columns 4 through 5 0 -0.007071067811865 0 0.007071067811865 0 0.007071067811865 0 -0.007071067811865 0 0.007071067811865 0 -0.007071067811865
Verify output
Check number of attributes
nAttr=size(out,2)
nAttr = 5
Check the number of entries
nEntr=size(out,1)
nEntr = 6
Check class of output
cOut=class(out)
cOut = double
