MEMS Module
New Functionality in Version 6.4
Symmetry Factors for the Terminal feature
In the Advanced Settings section of the Terminal feature in the Electrostatics interface, there is now support for a Terminal area multiplication factor. This multiplication factor can be used to model the effects of symmetry. A connected load or circuit will then perceive the full device, even though the model includes only part of it. For details, see Symmetry Factors for the Terminal Feature in the release notes for the AC/DC Module.
GENERAL CONTACT
A new feature, General Contact, is available in the Solid Mechanics interface. This contact formulation is particularly useful when there are many different boundaries that can come into contact with each other. For details, see General Contact in the release notes for the Structural Mechanics Module.
SMOOTH PENALTY FUNCTION FOR CONTACT
A smooth penalty function has been added to the Contact and Interior Contact nodes. It is also available in the new General Contact feature. For details, see Smooth Penalty Function for Contact in the release notes for the Structural Mechanics Module.
Logarithmic strains
The control over the formulation of geometric nonlinearity in the Geometric Nonlinearity settings of the Linear Elastic Material node havs been updated to speed-up large strain analysis while giving virtually the same results as using full multiplicative decomposition. For details, see Logarithmic Strains in the release notes for the Structural Mechanics Module.
linear buckling for periodic structures
The Solid Mechanics interfaces now support the Linear Buckling study and study step. For details, see Linear Buckling for Periodic Structures in the release notes for the Structural Mechanics Module.
warpage
It is now possible to compute warpage with respect to a reference plane defined by the user. For details, see Warpage in the release notes for the Structural Mechanics Module.
reaction forces
New variables to compute reaction force and moments are available in the Solid Mechanics interfaces. For details, see Reaction Forces in the release notes for the Structural Mechanics Module.
continuity
A new checkbox, Correct for mismatching boundaries, has been added to the settings in the Continuity node. For details, see Continuity in the release notes for the Structural Mechanics Module.
Default plot of total stored energy
A new default plot of total stored energy, Wh_tot, is available for Frequency Domain studies with electromechanics or piezoelectricity coupling. The default plot provides a visualization of the frequency response and resonance peaks of an electromechanical system.
