WebParameter Grids. If no tuning grid is provided, a semi-random grid (via dials::grid_latin_hypercube()) is created with 10 candidate parameter combinations. When provided, the grid should have column names for each parameter and these should be named by the parameter name or id.For example, if a parameter is marked for … WebStructural contact modeling is a highly non-linear problem. As surfaces come in and out of contact, load paths and stress states will abruptly change. The numerical solvers within COMSOL Multiphysics expect some degree of smoothness to the solution, so solving such models is inherently challenging. Most contact models will require some changes ...
