A solver interface is made up of a template and a FE-input reader.
Browsers provide a structured view of model data, which you can use to review, modify, create, and manage the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting, which enhance your ability to navigate and interact with the model data.
Create and edit 2D parametric sketch geometry.
Create, edit, and cleanup geometry.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Explore the different types of mesh you can create in HyperMesh and create and edit 0D, 1D, 2D, and 3D elements.

The Model Correlation utility determines the degree of similarity or correlation between two sets of results.
Modal Assurance Criterion (MAC) is a measure of the correlation between two vibration shapes.
PreTest allows prediction and optimization of the sensor locations (accelerometers) for measurements and directions along with test excitation point location, a very important step in the experimental modal analysis process directly affecting the accuracy of test results. Driving point residue (DPR) calculation gives information on optimum point for excitation location.
Frequency Response Assurance Criterion (FRAC) is a measure of the correlation between two frequency response functions (FRFs) representing the same input-output relationship.
Predicts powertrain rigid body mode frequencies and kinetic energy distribution, which play a critical role in optimizing the mount stiffness and layout configuration, by decoupling powertrain rigid body modes and reducing vibration transmission.
