WebJan 16, 2024 · Unless you put other constraints on your Helmholtz decomposition, it is not unique in general. Take any vector field which is both divergence and curl free. You can add and subtract this vector field in any way you like in the the decomposition and still come up with a Helmholtz decomposition. WebThink of a curl-ful field as a whirlpool--you could imagine going around and around and building up speed in it. But a curl-free field might be more like a river. You can flow down the river, but if you go back and forth down the river you spend as much time going up as you do going down, so you can't get anything out of it.
