Solution Utility Nodes The following sections describe the solver utility nodes (listed in Table 19-8) and the settings in detail. Table 19-8: Solution Utility Nodes Icon Name Description Adaptive Mesh Refinement (Utility Node) Stores the solution on the finest mesh from a mesh refinement procedure. Assemble Provides a way of accessing assembled matrices and vectors for further work in Java®. Compile Equations Compiles equations by specifying which study and study step to use and specifying representation of complex variables. Copy Solution Copy the complete solution results from another solver, including all dependent variables. For and End For Add a for loop to the solver sequence to iterate some solver commands. Input Matrix Used to create the raw data of an assembled matrix or vector from Java®. Solution Store Stores the solution at this point of the solver configuration also after the solver configuration has been computed. State Space Provides a way of accessing state-space matrices for further work in Java. About Solver Commands in the COMSOL Multiphysics Programming Reference Manual.
