1.4 Dynamic Response with Simcenter Nastran Sol107-112

This email address is being protected from spambots. You need JavaScript enabled to view it.

Duration

2 days

Description

This seminar deals with the Simcenter Dynamic Response solutions, which allow calculation engineers to analyze excited vibrations.

Both the direct and the modal approach as well as analyzes in the time and frequency domains are discussed in more detail. Therefore the Nastran solutions SOL 107, SOL 108, SOL 109, SOL 110, SOL 111 and SOL 112 are examined in more detail and the methods for a successful application of these solutions are trained.

In this seminar only the linear dynamic solutions from Simcenter Nastran are dealt with. In the seminar "Advanced Nonlinear Methods with Simcenter 3D" the nonlinear solutions SOL 601/701, SOL 401/402 are explained.
