System Matrix
Use a System Matrix () derived values node to evaluate a matrix defined in an Assemble or Modal Solver node to a table.
Solution
Select a Solution from the list to specify which Solver branch to tabulate the system matrix for. From the Solver feature list, select the Assemble or Modal Solver node that computes the system matrix.
Output
Select a Matrix: Stiffness matrix (the default), Damping matrix, Mass matrix, or any other system matrix that the selected Assemble or Modal Solver node computes.
First select the system matrices to assemble or compute in the Settings window for the Assemble or Modal Solver node and then compute the solution so that the solver stores these system matrices. Selecting a system matrix that has not been computed and stored results in an error.
Select a Format: Sparse (the default) or Filled. The system matrices can become very large but are usually sparse (most matrix elements are zero). If Filled is selected, the preference setting for the maximum filled matrix size (the default is 100) prevents the creation of a table with a very large matrix. Typically, when this is an Assemble node, a filled matrix output can only be used for very small models or when using reduced matrices.
When the System Matrix is a Modal Solver, the matrices of interest are typically small and filled.
