Is posible make a hydrostatic pressure boundary? Hydrostatic Pressure Application in pressure vessel - YouTube I usually define functions in codeaster

Hi @camilomati!
You could use the formula
\text{Pressure = density * gravit. acceleration * height/depth}
or
P = \rho * g * \Delta h
This can either be done via table upload or by using a formula like you did. An (inconvenient) workaround would be to split the faces in the vertical direction and apply a formula for each “layer” of the splits with increasing \Delta h going in -y direction.
Hope that helps a bit!

Yes, but i wanna new boundary condition for hydrostatical pressure like comercial software 
look my new project SimScale
have great weekend jousef
Hi @camilomati!
I do not know if Code_Aster provides a dedicated BC for hydrostatical pressure. The only thing I could find related to that was this document: https://www.code-aster.org/V2/doc/v12/en/man_u/u1/u1.05.00.pdf
@rszoeke, do you know more here?

Hi @camilomati,
as far as I know there is no special hydrostatic pressure load available in code-aster,
but wouldn’t the benefit be marginal as you can easily set a formula for it?
