Use a System Matrix (
) derived values node to evaluate a matrix defined in an
Assemble or
Modal Solver node to a table.
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.
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.
