This IMA quantity in arithmetic and its purposes source restoration, CONFINEMENT, AND REMEDIATION OF ENVIRONMENTAL risks includes papers awarded at profitable one-week workshops: Confine­ ment and Remediation of Environmental risks hung on January 15-19, 2000 and source restoration, February 9-13, 2000. either workshops have been critical components of the IMA annual software on arithmetic in Reactive movement and delivery Phenomena, 1999-2000. we wish to thank John Chadam (University of Pittsburgh), Al Cunningham (Montana country Uni­ versity), Richard E. Ewing (Texas A&M University), Peter Ortoleva (In­ diana University), and Mary Fanett Wheeler (TICAM, The collage of Texas at Austin) for his or her very good paintings as organizers of the conferences and for enhancing the complaints. We take this chance to thank the nationwide technology origin for his or her help of the IMA. sequence Editors Douglas N. Arnold, Director of the IMA Fadil Santosa, Deputy Director of the IMA v PREFACE Advances in source restoration, and confinement/remediation of envi­ ronmental risks calls for a coordinated, interdisciplinary attempt related to mathematicians, scientists and engineers. The reason of this selection of papers is to summarize contemporary theoretical, computational, and experimen­ tal advances within the idea of phenomena in porous media, with the cause to spot similarities and changes relating purposes with regards to either source restoration and confinement and remediation of environmental hazards.

Example text

In particular, the single phase flow model needs a boundary condition imposed on only one variable, specifically, on its subdomain solver primary variable 1 Pw . Also, the single phase subdomain solver delivers values of flux for one phase only. The studies presented in the previous section show that the natural and efficient choice of the (mortar) interface variable for which we derive the Dirichlet boundary condition values p~ is water pressure Pw. Schematically, the algorithm is as follows. In every iteration, the interface algorithm comes up with values of interface degrees of freedom corresponding to one variable A = (Pw ) only.

In all cases discussed here the stopping criterium for the interface iteration was chosen to maintain mass balance up to 8 significant figures. All cases are run without preconditioner, as MULTIPHYSICS COUPLING FOR TWO PHASE FLOW 29 explained above. Figure 3 shows the profiles of solution at 10 days which corresponds to the first time step. Such an unusually large time step is used intentionally, in order to amplify the difficulties. The solutions are plotted separately in the interior of each block and so there is a "gap" between the plots at 400'.

The mortar finite element space Mhkl is defined on a rectangular grid 1hkl on r kl , where hkl is associated with the size of the elements in 1h kl . In this space we approximate the interface pressures and saturations, and impose weakly normal continuity of fluxes. , = {p : pie = a : a E R, for all e E 1h kl }· If the grids adjacent to rkl are non-matching, the interface grid need not match either of them. 3). We define our non-matching mortar space on an element e E 1h kl by M'h(e) = {a66 + /36 + ')'6 + 6: a,/3, ')', 6 E R}, where ~l are the coordinate variables on e.
