Introduction

Generating a Modal Neutral File (MNF) from a finite element (FE) model requires that you perform a special analysis on the model in the finite element analysis (FEA) program and then translate the output of the analysis to an MNF. Generating an MNF is usually performed by a finite element analyst or an Adams user with experience running a finite element program. Once you generate the MNF, you can distribute the MNF to other users for use in Adams Flex.

The entries in this section describes the aspects of a finite element model you should consider before you generate an MNF, and explain the steps you perform to generate an MNF using different FEA programs.

They assume that you know how to run Adams Flex, Adams View, and Adams Solver. They also assume that you have a moderate level of finite element modeling proficiency. You need access to an FEA program that interfaces with Adams, so you can prepare an FE model for use with Adams and create an MNF to be built into your Adams model.
