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.
