questions about groovyBC
 
1)have totalPressure and totalTemperature been defined in groovyBC?
2)have it been assigned a piecewise function for having discrete values at different times in a discontinue manner?such that we can say for example since t0 until t1 velocity is such and such and since t1 till t2 such and such.

In the library groovyStandardBCs there is a boundary condition groovyTotalPressure that allows setting the totalPresseure from an expression. t serves as an example on how to "groovify" standard boundary conditions. Same would be possible for totalTemperature but I currently have no intention to do this (but I'd accept contributions)

You can use the "a ? b : c"-operator which means "if a is true take b else take c". Or a timeline with two values very close to the jump

thank you.it helps me a lot.
how can it be used exactly.where is the example you have mentioned?a clear example is appreciated.
How totaltemperature could be used then?
