MHARNESS

MHARNESS is a multi-conductor, multi-shield, multi-branched cable harness transmission line solver. Each cable harness branch can contain layers of shields, wires, and conductors - all immersed in a variety of respective media. Within MHARNESS are algorithms to analyze electromagnetic coupling through various cable shields to the conductors and wires within. Cable connectors, often possessing different impedance characteristics then the cable itself, are easily defined and employed. A variety of methods are available to terminate each conductor, wire, and shield within a cable harness, including circuit terminations. Many types of sources are available to drive the cable system including pin voltages, electric fields, current sources, and plane wave sources.

This section of the user manual describes the procedure for preparing, solving, and post-processing the simulation in MHARNESS.

MHARNESS uses Ansys Discovery to draw or import the model geometry, clean the imported geometry, and generate the model mesh.

The user interface is a ribbon-based interface. All the menus and tools are available in the ribbon shown below:
