Q: If I upgrade to V-Grade 5S or V-Grade 5S Plus can I open old experiments saved with V-Grade 5? 
A:  Yes, you can open experiments that you built and saved with V-Grade 5. In other words, V-Grade 5S and V-Grade 5S Plus are retro compatible. 

Q: In V-Grade 5S, can I directly open surface files that I saved with V-Grade 5. 
A: Yes, you can open them directly. You cannot, however, directly open old configuration or mask files as there have been formatting changes. To convert these old component files you should open them within experiments (saved with V-Grade 5) then re-save the components in V-Grade 5S or V-Grade 5S Plus.

Q: Does it take a long time to learn V-Grade 5S or V-Grade 5S Plus? 
A:  No. Given their extensive features and capabilities, they are very intuitive and easy to use. If you follow the "Quick Starter" manual sections and build-in examples you will begin to study your own cases in a few minutes. 

Q: Does the computation take a long time? 
A: The computation time ranges from few seconds to a few minutes, depending on the case. For an evaporation-mode case it typically takes a few seconds; for a sputtering source to coat a large two-dimensional surface in a planet fixture, it can take a few minutes. 

Q: What license terms are available? 
A:  We currently offer 1-year and 2-year licenses of V-Grade 5 and V-Grade 5S. 

Q: How is a license controlled? 
A: You will be given a license key (hardware) with the software.
