Detailed Description

constrains the dofs based on level set function.

Any dofs that are completely on the negative side are constrained.

if set to true, then if the element has a node on negative side of the level set, we will constrain all dofs of the node to be zero.

If false, then nodes will be constrained only if they get no contribution from elements with a positive level set region.
