Hello everybody!

first of all, I would like to thank you for the help you provide!

My case is quite simple,

it's a 2d case, a plate with a hole (geometry like case ''plate with a hole'')
https://cfd.direct/openfoam/user-guide/platehole/

but i have an inlet that is the hole with fluid and an outlet ( a face of the plate)

i dont know why but when i run my case with interFoam after several minutes my simulation fails without any iteration.

At time t=0 the water is located in the center of the hole.
i set this boundary with ''sphereToCell'' in the setfields file


the radius of region of alpha water is the same as the hole,


volScalarFieldValue alpha.water 0
);

regions
(
sphereToCell
{
centre (0.2 0.2 0);
radius 0.02;




sMy p rgh file


FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p_rgh;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [1 -1 -2 0 0 0 0];

internalField uniform 0;

boundaryField

}

p0 uniform 0.0;
gamma 0;
}
opposite hole face
{
type zeroGradient;

}
