Simpleware is an easy-to-use and very powerful tool. I have created a few scripts which help reduce the overall processing time even more. Simpleware has in-built tools to generate pore network reports and particle analysis reports which gives very good information about the bore same we get. It also eventually helps in reservoir study. Our group has validated the results from Simpleware to the experimental results only to find them very accurate.
QuantumATK provides us with the easiest way to do theoretical work. From the past few years we were doing only experimental research and now by using QuantumATK, we are saving time as well as money. In the latest version they have added the Sentaurus Materials Workbench which is a boon for us, now we are also able to simulate the layer properties of devices which we will build in Sentaurus TCAD in QuantumAtk itself, and then export the build and properties there. This has made our calculations much more accurate and reliable. Sometimes when we are working only on materials, we use the VASP link so that we can build the structure and export it to VASP for simulation.
