The building page is the page that is displayed once the simplex has finished fitting your experimental data or you are working without an experimental data file and adjusting the fitting parameters to create a unit cell. The building operation needs to be carried out before the properties of any unit cell can be characterised and investigated.

 

The building page is shown for the Clashac outcrop sandstone in the next image, with a fitting distance of 1.28% using the default fitting parameters. The left hand side of the screen shows the experimental data intrusion curve in red and the simulated intrusion curve in blue. The smaller the fitting distance the closer the simulated fit is to the experimental data.

The building screen above shows the fit that will be used when creating the unit cell, the fitting parameters can be found in the parameters sub menu or you can view the fitting parameters by exporting the simulation in PDF or CSV format. The parameters sub menu also allows you to change the solid phase material by selecting a different material in the materials database.

 

Click on the Accept or Go home button to return to the home screen, which will then show the operations list for the initialisation tutorial.

 

If you click on any operation in the operation list on the home screen and expand the details section on the right hand side of the screen you will see some key details about the operation.

Unit cell viewing

 

Double click on the Unit Cell Building operation and this will activate the unit cell viewing systems. You get a choice of the 3D cell inspector, 2D cell inspector and a full screen 3D viewer. The following figures show screen shots of the Clashac outcrop sandstone unit cell viewed using all three of the systems. The calculation tutorials will explain the unit cell inspectors in more detail and some of the more advanced functions.

Reporting and saving files

 

To save files or export the operations in a PDF format or spread sheet format, open the file menu and click on save as, this provides you with a choice of three options. Save as PoreXpert file, CSV or PDF. The Porexpert file allows you to reopen the file and continue adding additional operations. The PDF reporting and CSV reporting generate a PDF report summarising the operations list, and the CSV report creates a spreadsheet for each operation in the operation list to allow users of the software to combine graphs from different samples.

 

Please note that generation of PDF reports takes time, as the software needs to plot graphs and create unit cells.

 

Save the data in all three formats so you can see the outputs from the reporting operations and this concludes the initialisation tutorial. The next tutorial is the engineering tutorial, or you can progress to the calculation or analysis tutorials.
