         VERSION HISTORY of MLU for Windows


MLU 2.15: February 2010

* The maximum number of pumping periods per well is set to 50.
* During the optimization process calculations can be interrupted 
   with the [Stop] button. An interruped optimization process can be 
   continued [Run] or stopped [Cancel].
* When MLU has found a solution the user has to either accept 
   or reject the results.
* The MLU button on the Windows taskbar shows the file name of 
   the current model.


MLU 2.07: December 2009

* The red Optimize button turns blue when optimization results 
   become available for the present model
* The "Previous graph" button temporarily brings back the previous 
   Time graph for a comparison with the present graph, to detect 
   slight differences
* The width and height (in pixels) of the Time graph and the 
   Contour plot window are displayed on the Status bar when the 
   size of the window is modified
* The size (in pixels) of the Time graph or Contour plot can be set
   by the user before a bitmap is copied to the clipboard.


MLU 2.00: September 2009

* Time graphs only display curves for observed and pumped wells 
   by default
* Table type selection of time graphs and colors for drawdowns 
   and well-face fluxes
* Use of cursor for point inspection of observed and calculated 
   drawdowns and well-face fluxes
* Fast resetting of all drawing options
* Improved grid generator for up to 2.000.000 m wide FEM models 
   of up to 30.000 nodes per layer 
* Context sensitive Help screens.


MLU 1.60: January 2009

* Only non-negative skin factors can be entered
* Maximum number of observation wells is set to 50, while the
   maximum number observations per well is increased to 100
* The Stehfest parameter may be choosen within the range 6 - 16
* Optimization parameters are saved in MLU files
* All computations are performed with double precision accuracy.
  

MLU 1.20: October 2008

  Pumping Wells:
* Maximum number of pumping wells is 300.
* User selection of pumping wells and/or pumping periods 
   to be included/excluded from the time graphs and contour plot 
   computations and the optimization process.

  Observation wells:
* Maximum number of observation well is 300.

  Export:
* Saving of the model input data (not the computed heads) as a 
  Finite Element Model in a FEM format, ready for reading by MicroFEM.
  The number of nodes is limited to 50 000 per layer.
  The number of aquifers is limited to 20; 


MLU 1.10: September 2008

  Aquifer System:
* Zero-thickness resistence layers in stratified aquifers are allowed. 
  In such cases the vertical resistance (c-value) is computed as: 
  (thickness upper layer + thickness lower layer)/(2 * Kv).

  Pumping Wells:
* Numbering of pumping periods per pumping well. 
* Checking of the order of entered starting times per pumping well.

  Observation wells:
* Numbering of measurements per observation well.
* User selection of observation wells and/or individual measurements 
  to be included/excluded from the optimization process

  Export:
* Saving of the heads (or fluxes) that are computed to draw all 
  time-curves in a FTH-file format.


MLU 1.00: April 2008: 

* First release of MLU for Windows
