The General Form PDE node is the default equation for
The General Form PDE Interfaces, and it is available for the other forms from the context menu. Specify the coefficients for a general form PDE (see
The General Form PDE and
Equation 16-1).
Enter values or expressions for the components of the conservative flux vector Γ. The default values
-ux,
-uy, and -
uz (in 3D) represent the negative gradient of
u and makes the left-hand side equal to the Laplace operator. If there are multiple dependent variables, there is one
Γ vector for each variable.
