Calculation of contact interaction between countable domains using TIM-2D technique. The technique TIM-2D allows to calculate contact interaction between countable domains using the grid of arbitrary polygons with arbitrary number of connections in nodes. The nodes with arbitrary number of connections are allowed on the boundary. Described here are the following algorithms for boundary computation: rigid wall, free boundary, the boundary between countable domains with tangential discontinuity and the boundary between countable domains without tangential discontinuity. Also given here is the description of computational algorithms for triple points and boundary conditions change. The realized algorithms are verified using the series of test and method computations. It is shown that contact interaction computation does not impair the accuracy of solution and allows to keep Lagrangian boundary lines between the countable domains.
