The Coefficient Form PDE node is the default equation for
The Coefficient Form PDE Interfaces, and is available for the other forms from the context menu. Specify the coefficients for a coefficient form PDE (see
The Coefficient Form PDE and
Equation 16-2)
Enter a value or expression for the diffusion coefficient c. Select
Isotropic,
Diagonal,
Symmetric, or
Anisotropic and enter a
c coefficient on various forms in 2D and 3D. If there are multiple dependent variables, there is a matrix of
c component inputs.
Enter a value or expression for the absorption coefficient a. If there are multiple dependent variables, there is a matrix of
a component inputs.
Enter a value or expression for the source term f. If there are multiple dependent variables, there is a vector of
f component inputs.
Enter a value or expression for the mass coefficient ea. If there are multiple dependent variables, there is a matrix of
ea component inputs.
Enter a value or expression for the damping or mass coefficient da. If there are multiple dependent variables, there is a matrix of
da component inputs.
Enter values or expressions for the conservative flux convection coefficient α vector’s components. If there are multiple dependent variables, there is a matrix of
α vector component inputs.
Enter values or expressions for the convection coefficient β vector’s components. If there are multiple dependent variables, there is a matrix of
β vector component inputs.
Enter values or expressions for the conservative flux source term γ vector’s components. If there are multiple dependent variables, there is a vector of
γ vector component inputs.
