We attributed this fact to a bad annulment of self-interaction term by the exchange functional that leads to overstabilization of molecular systems by density functional methods.
One consequence of pointwise mass conservation and inf-sup stability of the element is that an arbitrarily large penalization of the divergence constraint for any [([P.sub.k]).sup.d]-based element on barycenter refined meshes does not lead to overstabilization or locking phenomena, regardless of the supplementing pressure space (and in particular it holds for any of the velocity-pressure pairs ([([P.sub.k]).sup.d], [P.sub.k-1]), ([([P.sub.k]).sup.d], [P.sub.k-2]), ...
In the present paper we show that with barycenter refined meshes and k [greater than or equal to] d, direct discretizations of (1.2) will provide optimal accuracy (no locking or overstabilization) and keep the sparsity structure of matrices reasonable for direct solvers to be successful.
However, overstabilization of dunes can result in 'coastal squeeze' and loss of habitat where the landward position is fixed, i.e.
To remedy overstabilization, drain some of the pool water to waste (or perform a large backwash) and top off with fresh water.
Trichlor and dichlor both contain stabilizer (cyanuric acid), which can lead to overstabilization problems.
This NFPA Class 1 oxidizer is designed to prevent overstabilization and needs no predissolving.
