Common Mistakes: Not assigning materials to all the domains. Feature: Stationary Solver 1 (sol1/s1) Adaptation gives the - COMSOL k(T) = 10[W/m/K]+10[W/m/K]*(T>400[K]) That is, start by first solving a model with a small, but non-zero, load. With respect to any nonlinearities, replace them by a reasonable linearized term. Iterative - COMSOL Multiphysics The advantages of the continuation method are two-fold.

Discussion Closed This discussion was created more than 6 months ago and has been closed. Trying to understand how to get this basic Fourier Series. Posted 26 set 2019, 11:57 GMT-4 Here, we begin an overview of the algorithms used for solving nonlinear static finite element problems. The default Initial Values for the unknowns in most physics interfaces are zero. Cecilia M. came from the backroom to help me and went out of her way to help me even though I had not called before going into the store. For example, if ramping P over values of: 0.2,0.4,0.6,0.8,1.0 the nonlinear solver may fail to converge for a value of 0.8. It is also possible to manually refine the mesh. Solver . I want to conduct a simulation to find a solution (u) and its first derivative (ux) using a 3D stationary model. There are two approaches that can be used when iteratively solving the nonlinear system of equations: a Fully Coupled or a Segregated approach. If your matrix is singular than no solver in the world can solve Ax=B. Each physics is thus solved as a standalone problem, using the solution from any previously computed steps as initial values and linearization points. P&S Comsol Team: Manuel Kohli, Raphael Schwanninger, Feature: Stationary Solver 1 (sol1/s1) In that case, the continuation method will automatically backtrack and try to solve for intermediate values in the range of 0.6 through 0.8. See if these can be used instead of explicitly modeling parts with high-aspect ratio geometries. Ramping the nonlinearities over time is not as strongly motivated, but step changes in nonlinearities should be smoothed out throughout the simulation. There will always already be either a Segregated or Fully Coupled feature beneath this.
