Hello, everyone.

Is the unit of time t in the source term is seconds (s)? For example, I want the source term to work within 1 subtle (us), then I make the working interval is 0≤t<1e-6. Is this right?

With best regards

In PyFR we don’t assume or impose any units, you might like to have a look at these two topics where it is discussed:

Ok, that means when I use the dimentional values in the .ini file, then times t in the source term is SI, and it’s unit is seconds?

If you intend for your mesh to be interpreted as 1 is 1m and your velocity is to be interpreted as 1 being 1ms^{-1}, then yes your time will be in seconds.
