hello
my geometry is cylinder and my BC is velocity inlet and pressure outlet and my fluid is turbulent water.
i added a force to momentum equation . i can see the changes in my pressure in outlet and inlet but my velocity should be change with same trend. why my velocity is fixed?
how can i simulate this? i mean my velocity should change with out using UDF.
is it possible?

regards,
Mo.Movaffagh

lolx i do have the oppsite problem i am adding source at a specific location my velocity is changing but pressure remains same

hi ebrahem
i know when we use from a BC for example velocity inlet or pressure outlet it will be fixed at that surface. but i want it change and i dont know how it can possible.
