help Rec23
  ABAQUS creep strain (including swelling) output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec23(#Rec#)
 
  Description
      Read creep strain output (including swelling) from the results
      (*.fil) file generated from the ABAQUS finite element software. The
      asterisk (*) is replaced by the name of the results file. The record
      key for creep strain output is 23 (only in ABAQUS/Standard). See
      section "Results file output format" in ABAQUS Analysis User's manual
      for more details.
      The following options with parameters have to be specified in the
      ABAQUS input file for the results (*.fil) file to be created and to
      contain creep strain results:
          ...
          *FILE FORMAT, ASCII
          *EL FILE
          CE
          ...
      NOTE: The results file (*.fil) must be placed in the same directory
      with the MATLAB source files in order to be processed.
      
  Input parameters
      #Rec# (string) is an one-row string containing the ASCII code of the
          ABAQUS results (*.fil) file. It is generated by the function
          Fil2str.m.
  
  Output parameters
      #out# ([#n# x #m#]) is a double array containing the attributes of
          the record key 23 as follows:
          Column  1  –  First creep strain component. 
          Column  2  –  Second creep strain component. 
          Column  3  –  Etc; followed by the equivalent creep strain,
          volumetric swelling strain, and magnitude of creep strain.
          where #n# is the number of elements multiplied by the number of
          integration points multiplied by the number of section points
          (for shell, beam, or layered solid elements) multiplied by the
          number of increments, and #m# is the number of creep strain
          results of each element. If the results file does not contain the
          desired output, #out# will be an empty array
