def setupPDE_vector_calculus(gridSize, equation):

    pde = PDE(gridSize, gridSize)
    pde.setEquationExpression(PDEExpressionType.VECTOR_CALCULUS, equation)
    pde.setVectorVariable("r", dimension=2)
    pde.configureGrid()

    return pde

Example #2

def setupPDE_vector_calculus():
    # 3. Equation as vector calculus without aux function eps
    pde = PDE(64.0, 64.0)
    pde.setEquationExpression(PDEExpressionType.VECTOR_CALCULUS,
                              "div(grad( u(r) ))")
    pde.setVectorVariable("r", dimension=2)
    pde.configureGrid()
    return pde

Example #3

def setupPDE_vector_calculus_with_eps():
    # 4. Equation as vector calculus with aux function eps
    pde = PDE(64.0, 64.0)
    pde.setEquationExpression(PDEExpressionType.VECTOR_CALCULUS,
                              "div(eps(r) * grad( u(r) ))")
    pde.setVectorVariable("r", dimension=2)
    pde.setAuxiliaryFunctions({'eps': eps})
