Hello, everyone
I know there are three entrance boundary conditions in Star-ccm +.
The first is the velocity inlet. The second is the mass flow inlet. The last is the stagnation inlet.
However, what I want to analyze is that the inlet pressure rises to 0-60 seconds, and the velocity also rises.
Here, the concept of total pressure seems to be interpretable.
However, I do not know how to set the total pressure inlet. Help me.

Crate a table in Excel with first column as time, then second as the variable you want to vary, in your case, it is total pressure, right!!

Then save it as .csv and at BC's node, import this table in tools>table node in Star-ccm+ file. Then in BC's node, at inlet, choose input method as table. Choose column for pressure if you have multiple columns. I am considering that your pressure BC's is varying with time. Hope this helps.
