help Rec38
  ABAQUS mass concentration (mass diffusion analysis) output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec38(#Rec#)
 
  Description
      Read mass concentration (mass diffusion analysis) output 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 mass concentration output is 38 (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 mass concentration results:
          ...
          *FILE FORMAT, ASCII
          *EL FILE
          CONC
          ...
      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 1]) is a double array containing the attributes of
          the record key 38 as follows:
          Column  1  –  Concentration.
          where #n# is the number of elements multiplied by the number of
          integration points multiplied by the number of increments. If the
          results file does not contain the desired output, #out# will be
          an empty array
