gp.pp

Syntax

f := gp.pp(gp)

gp.pp(gp<,i>) := f

Get/set the gridpoint pore pressure.

When the function is used to set the fluid pore pressure and the optional argument i is set to a nonzero value, in addition to modifying the gridpoint pore pressure, the function will update the accumulated pore pressure increment since the last mechanical step. The fluid flow calculation must be active for this option to be performed. To achieve the same result as the command zone gridpoint fix pore-pressure f, the FISH intrinsics gp.pp.fix and gp.pp must be used together.

Returns:

f - the current gridpoint pore pressure

Accepts:

f - the new gridpoint pore pressure

Arguments:

gp - a zone gridpoint pointer

i - if nonzero during assignment, indicates that coupling will be activated based on the change in pore pressure
