Hello everyone,

I am using fixed pressure value in my simulations now. But I would like to use a pressure table that drops in time. Do you know how to do it?

Thank you,
Yasemin

Hi,

There are several built in BC's that support this. You can find them by running:

    find $FOAM_SRC/finiteVolume/fields/fvPatchFields -type f | \\ 
        xargs grep -l Function1 | xargs dirname | sort -u

For your specific application you might find uniformFixedValue or uniformTotalPressure of use. Something like this:

  inlet 
  { 
      type         uniformFixedValue; 
      uniformValue table ((0 0) (10 2)); 
  }

If you need something more advanced than the built in functions (which are: table, csv, square, ramp, sine, polynomial) you could take a look at groovyBC (swak4foam)
