Analysis solution

Before you perform the pre-test, correlation, or model update solution process, you must have a Simulation file that contains an appropriate analysis solution.

You prepare the finite element model for the structural or acoustic analysis by defining the mesh and material properties.

The following table identifies the solutions that can be used for pre-test, correlation and model update solution processes.

Analysis solution with a reduced mass matrix

The structural modal correlation and model update solution processes can compute cross-orthogonality matrix if there is a reduced mass matrix in the .op2 file of the work solution.

For more information, see Create an analysis solution containing the reduced mass matrix.

Analysis solution, Simcenter 3D 2021.1 Series

© 2020 Siemens

The analysis solution can contain a reduced mass matrix.

A SOL 200 license is not required but to run a MSC Nastran SOL 200 Model Update Solution, an MSC Nastran DMAP license is required.

The analysis solution can contain a reduced mass matrix.

The analysis solution can contain a reduced mass matrix.

Only supportd in the Simcenter Nastran solver.

In the

Degrees of Freedom

group of the

Unit Force

dialog box, check all translational degrees of freedom to allow transformation of the work FRFs from the work coordinate system to the reference coordinate system. The work and reference FRFs require consistent measure types (acceleration, velocity, or displacement).
