help Rec97
  ABAQUS pore fluid effective velocity vector output to MATLAB
  
  Syntax
      #Rec# = Fil2str('*.fil');
      #out# = Rec97(#Rec#)
 
  Description
      Read pore fluid effective velocity vector 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 pore fluid effective velocity vector output is 97 (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 pore fluid effective velocity vector results:
          ...
          *FILE FORMAT, ASCII
          *EL FILE
          FLVEL
          ...
      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 97 as follows:
          Column  1  –  Magnitude. 
          Column  2  –  First component. 
          Column  3  –  Second component.
          Column  4  –  Etc.
          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 pore fluid
          effective velocity vector components of each element. If the
          results file does not contain the desired output, #out# will be
          an empty array
