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.

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.

The sensitivity analysis results revealed that Young's modulus ( E) and critical energy release rate ( G c) are the main factors affecting the output results of the model.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. The results show that the use of the solid mechanics module and interfaces of the PDE and domain ODE and DAE are effective for phase-field modelling, and the proposed method could reasonably characterize the whole fracture process of quasi-brittle materials. In addition, considering that the PFM involves many parameters would create a significant amount of work for model calibration.Therefore, multifactor sensitivity analysis based on the orthogonal test method is used to identify the parameter' sensitivity. Combined with the collected tensile and shear numerical simulation data, validation studies are carried out both qualitatively and quantitatively.

#Comsol 5.3 release crack#

In this paper, a crack propagation model for quasi-brittle materials based on PFM is implemented in COMSOL Multiphysics by means of the solid mechanics module and secondary development interfaces of the partial differential equation (PDE), domain ordinary differential equation (ODE) and differential algebraic equation (DAE).

The essence of the PFM is a multifield coupling problem, so it is supposed that the COMSOL Multiphysics commercial finite element software, which is particularly suitable for solving multifield coupling problems, should be more efficient and simpler to implement for the PFM.

The PFM describes the fracture process through a series of differential equations, thus avoiding tedious crack surface tracking and offering advantages in simulating crack initiation, propagation, and bifurcation. Recently, the use of the phase-field method (PFM) to simulate the fracture process of brittle materials has attracted increasing attention.
