The upstream parameters can range all the way to infinity. If you want to use infinity as a parameter value, type a very large number, like 10000, instead. This will yield results differing little from the solution for infinity.
The upstream velocity is measured along the shock normal, and two temperatures are used as inputs to remind you that both temperatures are relevant. The module calculates only a single downstream temperature.
