The motion is nevertheless imparted to the fluid, because whenever the box finds itself in a cell which is larger than itself, it "expands" so as to fill the cell. This expansion is performed automatically within 'EARTH'. ENDDIS distil=t store(rsu1,aep1) ex(p1)=1.147E+00; ex(rsu1)=2.200E-07; ex(aep1)=2.095E-01 libref=374 stop
