Early versions of Pore-Cor

A non-graphics version was installed at the Tulsa Technology Center of Amoco in September 1995. A pre-release demonstration version D1.00, February 1997 was shipped to Micromeritics, Atlanta in February 1997. Version D1.01 was upgraded from version D1.00 by the inclusion of a two level Help system - i.e. brief for specific windows, from which lengthier discussions can be called up. It was tested at four sites between March and October 1997.
Relative to Version 1.00:
Version 1.01 has improved handling of fragmented networks and medium porosity samples.
Version 1.02 (March 1998) has a fix to ensure that the polymer pore plug algorithm communicates correctly with the permeability algorithm. A 'clear cell' output option has been added, and a user preference form.
Version 1.20 (July 1998) has facilities to monitor the positions of non-wetting fluids, polymer and colloids within the graphics, alter graphics colours and background, and to plot more than one unit cell. The number of small datafiles has been greatly reduced, in preference for additional communication with the Fortran 90 algorithms, and use of the Windows Registry.
Version 1.30 (October 1998) has a vastly improved Wizard, automatic datafile recognition for Autopore II files, automatic datafile manicure, greatly enhanced general help which can be tuned by use of a preferences menu, improved crash resistance, command button and approximation framework icons, and has been very extensively tested for bugs and ease of use. It also has CD autoload.

Pore-Cor Research Suite Versions 4.00 and higher

Pore-Cor Research Suite (beta release May 2002, full release Spring 2003) , Version 4.00, includes the following new features:

  • Parameters found using a Boltzmann-Annealed Simplex (instead of the Wizard which has been pensioned off).
  • The modelling is much more robust, for example it can now model sparse data which is not in the form of an S-shaped curve.
  • Many more structure types are available, as well as conical throats and anisotropic structures.
  • The entire Pore-Cor program interacts with a comprehensive data archive for storing and recalling modelling sessions, and any archive can be dumped to a MicroSoft Excel file.
  • The two-parameter grid method has been transformed into a four-parameter sensitivity analysis.
  • The user can now study dynamic wetting, either allowing or disallowing the inertia of the fluid.
  • Graphics of the unit cells are now presented in a virtual reality environment which the user can explore.

    .

  • Two other programs have been integrated with Pore-Cor.
    • Pore-Ped allows generation of water-retention curves for UK soils , via a pedo-transfer function, and for U.S. soils via the UNSODA database.
    • Pore-Comp allows the user to compensate for expansion and contraction effects during mercury porosimetry, and to calculate the solid phase bulk modulus of the sample.
    Higher versions include numerous fixes and modifications arising from testing by other users. The main additional features of each release, cumulatively included, are as follows:

    Version 6.01 (early June 2007)

    Operating system and overall
     
  • Several Thermo Electron data files have wrong units (cc/g rather than mm3/g) even though data itself is correct. So substitute example files provided. (#6.00.005)
  • Help | About drop-down menu now gives correct operating systems (XP and Vista). (#6.00.006)
  • Switchoffable warning message that Pore-Cor RS is running in debug mode. (#6.00.010)

    Pore-Comp
     
  • Graph title corrected to give correct sample name, rather than sample description details. Also gives correct output to Pore-Cor. (#6.00.011)
  • If Pore-Comp cannot calculate compressibility, it also cannot calculate porosity. Now correct handing of this problem for export to Pore-Cor. (#6.00.012)

    • Pore-Cor

  • Sample name shown in header of more output graphs. (#6.00.001)
  • Cancel Simplex command modified to give more orderly (and slower) exit to Simplex which does not then wreck subsequent calculations. (#6.00.002)
  • Error message stating 'In this datafile, throat diameter .... is greater... ' now gives better instructions about editing and saving the file. (#6.00.003)
  • Switchoffable message to remind users if Datafile Manicure system is switched off. Also extra switchoffable message before manicure messages to tell users they can switch off the manicure system. (#6.00.007)
  • Error handler position moved from early to normal position in code of Master Data input Calculate command. (#6.00.008)
  • For pore and throat size distribution and mercury intrusion / water retention graphs, using Chart drop Manual axis and then Quit gave error. Now exits cleanly. (#6.00.009)
  • Valid range of throat skew for unimodal samples increased from +-25 to +-36 to allow modelling of bare fallow soil. (#6.00.013)

    Pore-Ped

  • Bug corrected which gave error message if 12 of users own points were entered. (#6.00.004)

     

    Version 6.02

    Operating system and overall
     
  • Automatic knowledge of whether an upgrade is available. Reminder message to user giving chief characteristics of upgrade. (#6.01.022)

  • Sample name included in header of data review screen. ( #6.00.001, #6.01.021)

    • Pore-Cor
     
  • If Simplex form Cancel control is clicked during operation of Simplex, Simplex now stops cleanly. (#6.01.014)
  • Simplex no longer often defaults to showing user a choice of starting grids to choose from, since this option is now rarely used because the Auto option is available. (#6.01.016)
  • Stop Simplex button disappears if user agrees to stop the Simplex in response to a message from the Simplex. (#6.01.017)
  • If Simplex best fit has high throat spread but Simplex was set to unimodal only, now suggests to user that user tries Unimodal and Bimodal option. (#6.01.018)
  • Switchoffable warnings about manicure being switched on or off now operate correctly. (#6.01.015)

      Pore-Cor
       
    • Correction to number of throats generated for given connectivity by Euler beta function. Unfortunately this will alter the connectivity value for a given fit by up to 10% for strongly bimodal samples, and may also alter other fitting parameters as well because the geometric parameters are not orthogonal (independent). (#6.02.029)
    • Open or Save new data archive mistakenly used file extension *.st6 (which is reserved for Simplex starting grids) rather than *.sl6 (which is used for archives). Now saves and searches for *.sl6. Note that if you have saved an archive on a previous version, you may need to change its file extension manually from .st6 to .sl6 . (#6.02.027)
    • Wetting command is now switched back on if partial wetting is cancelled before data is checked. (#6.02.025)
    • Particle size distribution: top option (Actual volume...) now changes x-axis label from size to volume.(#6.02.024)
    • Thermo files now accepted with up to 2000 data points, but Manicure insists on reducing the number (i.e. option to ignore this warning is switched off). (#6.02.026)
    • Message that Manicure is switchoffable only appears for Advanced non-Thermo users. (#6.02.029)
    • Formation damage and save perm to data archive commands switched off on perm output form if using flow tracking option (#6.02.030)
    • Geometric values only, without a datafile, can now be stored in the archive and re-loaded into Master Data input without generating a 'Load valid datafile' error message (#6.02.031)
    • New manual calculations from the Master Data input, for example investigating the effect of changed connectivity with otherwise identical parameters, now close previous output-option property calculation windows to prevent confusion. (#6.02.032)
