"The software implements a mathematical model of movement of a Biot-type porous medium through the space of a 3D chamber allowing for Coulomb friction conditions on the walls, that can be used for modeling the oil extruding-expelling process of oilseeds in the screw press. A combination of Lagrangian and Eulerian description is used to describe the passing medium, where large deformations in time are solved by a sequence of subproblems for a small time increment in the Lagrangian formulation with updated deformed configuration. Those subproblems have form of the Biot model extended by a prestress originating in preceding time steps and transformed from the shifted, deformed domain back to the original, undeformed domain (Eulerian description). The Coulomb friction on the walls is taken into account using the non-smooth equation involving the complementarity conditions of friction forces and a multiplier."@en . . .
