It is discussed the problems which appear in time of modeling and ways of their solving. It is made a comparing analysis of different algorithms of solutions. For one – dimensional marginal tasks, when coefficients of differential eguations are constant, approximate analytical solution is done, and in the case of variability, it is developed the numeric algorithm of solution. Two-dimensional marginal tasks are Solved numerically by methods of fictive regions, residual variants of stream running, and on the unknown moving borders between different regions of filtration it was used the Methods of shuttled iterations.
