Encryption speed test19 June 2020
A problem with PoreXpert versions up to 1.8 was that the encryption necessary to protect the software slowed it down. Using newly purchased software we have been working to improve the speed of the most commonly used operations, and have successfully applied it so they now run comparably as fast for our users as for ourselves. The graph compares the speed of calculation for a (small) 12x12x12 unit cell, with about 4300 void features – fitting for Vertically Banded and Small Centre Zone structure types (short range size auto-correlations), absolute permeability to water at 20C, and ionic tortuosity.
Free cell viewer download11 June 2020
The cell viewer is now available as a signed Microsoft Installer file from the Downloads page, so that you can see void structures in virtual 3D on your own PC. Many interesting void structures of geometric and real samples are being loaded there.
PoreXpert version 2 security5 June 2020
We are now busy preparing the Sentinel security dongles and download system for the v2 alpha release.
v2 alpha release testing8 May 2020
We are currently vigorously testing PoreXpert V2, including non-English language versions as shown, prior to alpha release.
Revised user manual28 April 2020
PoreXpert version 2 is a significant advance on the previous version (1.8), so a new, nearly 200 page User Manual has been written to accompany it.
Improved tortuosity simulation26 March 2020
We have programmed an improved tortuosity simulation for PoreXpert version 2.
Automated cluster analysis succcess4 March 2020
Success ! We have managed to find a stable mathematical way of identifying the ‘cluster ratio’ for a particular samples, by means of which those voids that are likely to be clusters of smaller voids can be identified. A new PoreXpert operation and user interface have been designed and implemented by our programmer.
PoreXpert cluster analysis23 January 2020
The patented, world leading PoreXpert cluster analysis is very powerful, but currently requires trial and error to find out how many voids are likely to be clusters. We are therefore busy automating it.
Consultancy project10 December 2019
We are using the University of Plymouth’s world-leading Focussed Ion Beam Scanning Electron Microscope (FIB-SEM) as part of a major on-going consultancy project for a client.
Annual Symposium of the Society of Core Analysts – 20191 August 2019
We presented a poster (available from the downloads page) and summary oral presentation at the Annual Symposium of the Society of Core Analysts in Pau, France on 26-29th August 2019. The talk was entitled ‘Inverse modelling of nano- to macro-scale voidage within tight-oil shale’.
