help Rec1900
  ABAQUS element definition output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec1900(#Rec#)
 
  Description
      Read element definition 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
      element definition output is 1900. See section "Results file output
      format" in ABAQUS Analysis User's manual for more details.
      The following option with parameter has to be specified in the ABAQUS
      input file for the results (*.fil) file to be created:
          ...
          *FILE FORMAT, ASCII
          ...
      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 cell array containing the attributes of
          the record key 1900 as follows:
          Column  1  –  Element number. 
          Column  2  –  Element type. 
          Column  3  –  First node on the element. 
          Column  4  –  Second node on the element. 
          Column  5  –  etc. 
          where #n# is the number of elements and #m#-2 is the number of
          nodes per element. If the results file does not contain the
          desired output, #out# will be an empty array
