Troubleshooting for 3D trusses, if anyone's out there. : r/COMSOL - reddit My comment is perhaps a bit nave but it seems to me that you could simply deactivate the term of the background field equation but keep its connexion to the solid to get what you want. Near the top of the Stationary Solver log, the software will report if a linear or nonlinear solver is being used. Within either of these features, it can also be helpful to enable the Results While Solving option, as shown in the screenshot below, to visualize the iterations being taken during the solution. By default, the COMSOL Multiphysics software determines these values heuristically depending on the physics as, for example, the specified initial values or a solution from an earlier study step. However, it is usually not possible to know this ahead of time. There are two approaches that can be used when iteratively solving the nonlinear system of equations: a Fully Coupled or a Segregated approach. If so, see: Knowledgebase 1030: Error: "Out of memory". Also, keep in mind that a linear stationary model should solve regardless of how coarse the mesh is (albeit to a low accuracy) so you can always start with as coarse a mesh as possible, and refine the mesh (See also: Knowledgebase 1030: Performing a Mesh Refinement Study.

The algorithm is, generally speaking, a Newton's method approach. Load ramping and nonlinearity ramping can be used in combination, but start with only one or a few of the loads or nonlinearities being ramped. For example, in a Solid Mechanics (wherein the software is solving for the displacement field within the solid) applying two opposite and equal Boundary Load conditions on a part is not sufficient to define the displacement. k(T) = 10[W/m/K]*exp(-(T-293[K])/100[K]) At a value of P=0 the above expression is linear, and at a value of P=1 the expression is equal to the original nonlinear expression. The advantages of the continuation method are two-fold. In the extreme case, suppose one wants to model an instantaneous change in properties, such as: New Stationary Engineer jobs added daily.
