help Rec119
  ABAQUS electrical reaction charge output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec119(#Rec#)
 
  Description
      Read electrical reaction charge 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
      electrical reaction charge output is 119 (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 electrical reaction charge results:
          ...
          *FILE FORMAT, ASCII
          *NODE FILE
          RCHG
          ...
      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 2]) is a double array containing the attributes of
          the record key 119 as follows:
          Column  1  –  Node number. 
          Column  2  –  Charge scalar value. 
          where #n# is the number of nodes multiplied by the number of
          increments. If the results file does not contain the desired
          output, #out# will be an empty array
