Question about fluid flow using Inlet/Outlet
Hi, I've recently noticed something weird in my Inlet/Outlet simulations as shown in the picture below where there appear to be some sort of wave formation for a simple fluid flow without the presence of an object, even though I only specify a constant uniform velocity at the inlet. I would like to know if this is to be expected or is there something wrong with my settings. I have attached the XML file used for this simulation below. Thank you.
