Hello

I am investigating stationary shape bubbles, I managed to set up a case for circular stationary gas bubble in water, now I want to have an oval/ellipsoidal shape bubble. How can I define such a shape?
The circular/spherical one I defined in my setFieldsDict by
sphereToCell
{
centre ( 0 0.01 0 );
radius 0.0033;
fieldValues
(
volScalarFieldValue alpha.water 0
);
}

How to do something similar to have initially an oval shape bubble?

Hi,

I think you should look for funkySetFields, part of swak4Foam.

Tom is right.

This is my spherical bubble quickly converted to an ellipsoid for you:

funkySetFields -latestTime -keepPatches -field alpha.water -expression "sqr(pos().x-$x_b)/sqr(a)+sqr(pos().y-$y_b)/sqr(b)+sqr(pos().z-$h_b)/sqr(c)<1?0:1"
