1.This option can be used with fluid properties /PROP/FLUID (TYPE14) or /PROP/POROUS (TYPE15).
2.The algorithm can handle closure in any but in only one direction, namely when one element is already or is becoming flat.
3.The element closure treatment is activated whenever one element dimension is becoming smaller than the threshold value htest. When the element "thickness" becomes smaller than hclose, then a flow resistance is added in order to account for friction effects.
