ELEMENT DEFINITION output from Abaqus to Matlab (Record key 1900)

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\1900.inp'],[S(1:a(end)-1),'\1900.inp'],'f')

Run the input file 1900.inp with Abaqus

!abaqus job=1900

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('1900.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('1900.fil');

Obtain the desired output data

out = Rec1900(Rec)
out = 

    [ 1]    'FRAME2D'    [5]    [3]
    [ 2]    'FRAME2D'    [3]    [1]
    [ 3]    'FRAME2D'    [6]    [4]
    [ 4]    'FRAME2D'    [4]    [2]
    [ 5]    'FRAME2D'    [3]    [4]
    [ 6]    'FRAME2D'    [1]    [2]
    [ 7]    'FRAME2D'    [5]    [4]
    [ 8]    'FRAME2D'    [6]    [3]
    [ 9]    'FRAME2D'    [3]    [2]
    [10]    'FRAME2D'    [4]    [1]
    [11]    'MASS'       [1]    [0]
    [12]    'MASS'       [2]    [0]
    [13]    'MASS'       [3]    [0]
    [14]    'MASS'       [4]    [0]
    [15]    'MASS'       [5]    [0]
    [16]    'MASS'       [6]    [0]

Verify output

Check number of attributes

nAttr=size(out,2)
nAttr =

     4

Check the number of entries

nEntr=size(out,1)
nEntr =

    16

Check class of output

cOut=class(out)
cOut =

cell
