Ramping the total pressure boundary?

Siassei · July 16, 2020, 13:15

Hello,

is it possible to ramp the totalPressure boundary over time like the uniformFixedValue with table?

Thanks a lot.

Then a may be a function like this - not sure. Look for a version that will take an expression for p0.

However, don’t expect miracles - I have been tempted to try this a few times and it never did anything for me. Your problem is probably somewhere else.

There is uniformTotalPressure boundary condition.
You might want to check the tutorial:
incompressible/pimpleFoam/RAS/TJunction

Hope this helps,
