The engineering operations tutorials can be opened in PoreXpert, to look at the additional operations included with PoreXpert Professional and PoreXpert Cloud, but you will not be able to follow these tutorials, so you need to skip to the next section of tutorials. The engineering operations can be used to manipulate structures to ascertain how the filtration properties are changed, or the engineering operations can be used to perform a formation damage simulation by filling features smaller than a certain size with a material, reducing the network permeability.
