Hi,

There are several ways the foam can be born - it could be emitted from a source or born naturally from the simulation in areas with velocity difference above certain threshold or when splashes hit the liquid surface. You can check more about this here https://docs.chaosgroup.com/display/...quidFoam-Birth. You can try playing with the parameters Birth Threshold of the foam and Foam Amount of the splash to control where foam is born. However if you only want to restrict the area where foam can be born the best way would be to use Birth Volume for the foam and you can set fadeout for it to make it look more natural. Or if you just want to remove the foam from certain area you can use an object with Clear Inside https://docs.chaosgroup.com/display/...ies-Parameters enabled just for the foam.
