Create a cardioid geometry using four distinct techniques. The techniques are ways to parametrize your geometry using arc length calculations. The cardioid satisfies the equation .
A PDE model stores initial conditions in its InitialConditions property. Suppose model is the name of your model. Obtain the initial conditions:
Import a 3-D mesh into a PDE model. Importing a mesh creates the corresponding geometry in the model.
Use a geometry function to create a circular region. Of course, you could just as easily use a circle basic shape.
A PDE model stores coefficients in its EquationCoefficients property. Suppose model is the name of your model. Obtain the coefficients:
Create a geometry file for a region with subdomains and a hole. It uses the “Analytic” cardioid example from "Arc Length Calculations for a Geometry Function" and a variant of the circle
A PDE model stores boundary conditions in its BoundaryConditions property. To obtain the boundary conditions stored in the PDE model called model , use this syntax:
