help Rec120
  ABAQUS concentrated electrical nodal charge output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec120(#Rec#)
 
  Description
      Read concentrated electrical nodal 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 concentrated electrical nodal charge output is 120 (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 concentrated electrical nodal charge results:
          ...
          *FILE FORMAT, ASCII
          *NODE FILE
          CECHG
          ...
      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 120 as follows:
          Column  1  –  Node number. 
          Column  2  –  Current 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
