i did not find how i know the unites used in Nektar, like in velocity in pressure 

i tried to use it it is amazing but i need to know when i have velocity field which unit i see

also for pressure is it pascal bar dynes/cm2 i need to know, i checked the user guide not clarify this point, i checked tutorials one of them the graph of the pressure is in dynes/cm2 i don't know which unit i can have and where we can define like Si system unit or something.
