ESTECH.MODAL2FEM

Feature

• Convert equivalent physical test and/or analytical modal parameters created in I-deas universal file format to I-deas and MSC Nastran models.
• Applying the software makes it possible to handle MSC Nastran and/or analytical modal models as FE elements as well as to conduct Adams analysis including physical test modal model.
• The software can add rigid body characteristics to modal parameters which have no rigid body characteristics. This is because the low frequency rigid body mode cannot be extracted accurately by physical test, therefore it is necessary to add the rigid body characteristics later.
