Benefits: The ability to specify the incomplete LU factorization fill-in level for the iterative solver offers improved convergence for soil reservoir simulations.
Description: A new iterative solver option is available for soils and geostatic analyses. By default, the ILU factorization fill-in level is set to zero. In cases where the simulations do not reach convergence using the default level, you can increase the level up to three. The performance improvement is case by case.
