Hi,

I am going to simulate a single droplet falling in air by means of InterDyMFoam. To decrease the computational time I want to simulate half of the domain. So I need to have a hemisphere for the half of the drop in initial condition. Anybody knows How I can create a hemisphere by setFields or any other functions?

Thanks

you can use following instructions :

defaultFieldValues
(
volScalarFieldValue alpha1 1
);

regions
(
sphereToCell
{
centre (0 0 1.024E-03);
radius 0.512E-03;
fieldValues
(
volScalarFieldValue alpha1 0
);
}
);

Setting a sphere should work in your case right?

Dear Nima,

Thanks for your reply. But I suppose it is for a sphere simulation not a hemisphere, isn't it?

To make it a hemisphere, one can probably use a box to reset its value, I suppose.

Of course, this wouldn't be ideal if the plane of the flat surface of the hemisphere is at an angle.

Maybe combining it with topoSet and its rotated Box might help? Any comments?

1- change your perspective , you can easily obtain hemispherical with that command Hint: assign a valid centre!

2- but if you insist on draw hemisphere, use funkySetFields
