The high pressure can damage the optic nerve at the back of the eye, and may even result in blindness if left untreated. An eye doctor (ophthalmologist) can use tonometry to diagnosis glaucoma - an eye condition where fluid accumulates in the patient’s eye, causing high eye pressure. It is used instead of the Moving Mesh (ALE) physics interface, which is still available as an alternative to the new moving mesh functionality.A tonometer is an instrument that measures the internal pressure of the eye, which is also known as intraocular eye pressure (IOP). The moving mesh features available under Definitions are the new default mechanism for multiphysics interfaces with moving meshes. Other features can specify that parts of the model rotate such as in the case of fluid mixers or electrical motors. For example, Deforming Domain features, added under the Moving Mesh node, can be used for fluid domain deformations in fluid-structure interaction (FSI) or electrostatic domain deformations in microelectromechanical systems (MEMS). They can be used to study both stationary states and time-dependent deformations where the geometry changes its shape due to the dynamics of the problem. The moving mesh features control the spatial frame in a model and may apply to all physics in a model where the domains are deforming or moving. The Moving Mesh functionality is now available from the Moving Mesh submenu when right-clicking the Definitions node under a Component and from the Definitions toolbar. The list of physics interfaces also contains the original space dimension before the label of the interface. The Physics ribbon tab contains the Insert Physics from Model tool, which opens the Insert Physics dialog box where the user browses for a model and selects physics interfaces to insert into the selected component in the current COMSOL Multiphysics ® section.
COMSOL 5.3 INDIR WINDOWS
Since model methods require the Application Builder, they can only be created or edited in the Windows ® operating system, but method calls can be run and added for existing model methods on any platform.
The method inputs are displayed in the method call node's Settings window, automatically using the most appropriate form object type for the associated input type. You can even create multiple Method Call nodes using the same model method, in order to enter different default inputs for each node. The new Method Call node, a subnode of the Global Definitions node, enables you to supply inputs to your model methods. When creating and running methods, you may have certain inputs that you would like to specify before running your method. Model methods, introduced with COMSOL Multiphysics ® version 5.3, enable you to perform complex operations directly on the model you are working with, such as setting up geometry sequences from data in a text file, changing solver settings based on specific criteria, or creating template plot groups. Learn more about these and other COMSOL Desktop ® updates below.
COMSOL 5.3 INDIR SOFTWARE
For all COMSOL Multiphysics ® software users, version 5.3a brings method calls to model methods where you can specify method inputs, functionality for transferring physics interfaces or entire components between MPH-files, and improved handling of recovery files.
