Training programme

A typical programme for an on-line training programme comprising three 4-hour sessions: PoreXpert online training programme .

Stand-alone unit cell viewer

The unit cell viewer reads output files from PoreXpert (.pXt extension), and shows any unit cells within the output file in 3D virtual reality.  A range of structures are available from the datafiles download page. Alternatively you can view unit cells from your own saved PoreXpert output files.

To run the free viewer,  first download the Unit Cell Viewer installer.  Then read the instructions for use on the on-line  Help system.

Licence updater

Download this signed Remote Updater Software if your licence needs updating or upgrading, by means of changes to your hardware Sentinel LDK key (hardware dongle).  After downloading the zip file, unzip it and run it. RUS_PX_V2

Data thinner

Although PoreXpert can automatically input data from many makes of mercury porosimeter, if over-large data files are input directly, the simplex convergence algorithm works more slowly, and important points of inflexion tend to be under-weighted statistically.  What PoreXpert needs is around 100 points, equally spaced in two-dimensional parameter space comprising: log(throat-entry size), intrusion volume.

The zip file PoreXpert_input_data_thinner contains Python source code for thinning porosimetry data, which generates an output file in PoreXpert .csv format that can be read directly into PoreXpert. No data points are altered – but an appropriate number are skipped. The source code needs to be run in a Python IDE such as PyCharm.  The current version needs the data file path to be edited in manually.  Different data input formats can also be changed by manual editing if required.

The zip file also contains example input and output files.  Note that the example data file is for tight-oil shale – so has had an extra point added at 1 nanometre throat-entry diameter that has been measured by helium pycnometry.  Mercury porosimetry alone gives data down to 4 nanometres minimum.
