The effect of iteration frequency on a numerical model of near-surface ice segregation

It is possible to construct numerical models of the ice segregation process. However, the model is a discrete approximation of a nonlinear continuous process and thus is subject to somewhat more pronounced effects of node geometry and calculation frequency than linear models. The model more closely simulates natural frozen soil structure when vapor phase transport is included in the model structure. An iteration frequency of 10 s appeared sufficient to yield realistic results with the exponentially spaced node geometry employed in these tests.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23588/1/0000550.pd
