Prescribe pressure at inlet (Dirichlet)

[Seo Yeon Kim]

Hello,
I'm currently trying to prescribe pressure as a inlet boundary condition for the simulation using svFSI.
Looking through the posts that has been already posted on the forum, I have gain some information similar to my question.
But I am still unclear with some parts.

Is there a way to apply pressure as a Dirichlet condition in svFSI?

Also,
1-2. if it is possible to apply pressure as an inlet boundary condition using Dirichlet, is it correct to write as below at .inp file to run svFSI?

Add BC: inlet {
Type: Dir
Time dependence: Steady
Value: {Pressure value}
}

2. In case of svSolver, I have figured that GenBC is used to apply pressure as an inlet boundary condition.
Is GenBC also applicable for svFSI?

Thank you in advance

Hello,

You can also use GenBC in svFSI (see https://github.com/SimVascular/svFSI-Te ... oupling-BC).

However, it would be easier to use

Code: Select all

Add BC: inlet {
Type: Dir
Time dependence: Steady
Value: 100.0
}

Try it and see if it works.

Cheers,
Dave

Thank you for the comments.

I have one question regarding the comment that you gave me.

I have tried applying

Add BC: inlet {
Type: Dir
Time dependence: Steady
Value: 100.0
}

and by doing so, it turned out to be applying 100 cm/s velocity at the inlet not the pressure

Did i understood correctly?

Thank you

Hello,

Yes, sorry, it seems that Type: Dir only sets velocity.

You will need to use GenBC.

Cheers,
