model = createpde(N)
returns a PDE model object for a system of N equations. A
complete PDE model object contains a description of the problem you want to solve,
including the geometry, mesh, and boundary conditions.
model = createpde returns a PDE model
object for one equation (a scalar PDE). This syntax is equivalent to model
= createpde(1) and model = createpde().
createpde will no longer create the
StructuralModel, ThermalModel, and
ElectromagneticModel objects. These objects will be removed.
Use femodel to
create a unified finite element model instead.
For example, you can create a model for solving a thermal transient problem as
follows.
model = femodel(AnalysisType="thermalTransient")
The unified finite element model workflow defines the type of a problem and all of
its parameters as the properties of an femodel object. This
object enables you to specify physical parameters for structural, thermal, and
electromagnetic types of analyses. The solver in the unified workflow uses only the
parameters (properties) appropriate for the current analysis type while ignoring all
other properties. If you switch the analysis type by setting the
AnalysisType property of the model, the solver uses the
appropriate set of properties corresponding to the new analysis type.
For more help migrating your existing code that uses
StructuralModel, ThermalModel, or
ElectromagneticModel to the unified finite element workflow,
see Migration from Domain-Specific to Unified Workflow.
createpde now can create a model for electromagnetic
analysis.
createpde now can create a model for axisymmetric thermal and
structural analyses. Axisymmetric analysis simplifies 3-D structural and thermal
problems to 2-D using their symmetry around the axis of rotation.
createpde now can create a model for structural
analysis.
createpde now can create a model for thermal analysis.
