Renders the solution of the partial differential equation. You must manually select the polymorphic instance to use.

Inputs/Outputs

PDE in —

PDE in is the class that stores the data of the equation.

U(t, x) —

U(t, x) specifies the solution of the equation.

error in (no error) —

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

PDE out —

PDE out returns PDE in unchanged.

PDE Plot —

PDE Plot returns an intensity graph that renders U(t, x).

X Scale —

X Scale returns the offset and multiplier of the x-scale. X Scale returns the offset and multiplier of the PDE Plot x-scale.

Offset —

Offset returns the offset of the x-scale.

Multiplier —

Multiplier returns the multiplier of the x-scale.

Y Scale —

Y Scale returns the offset and multiplier of y-scale. Y Scalereturns the offset and multiplier of the PDE Plot y-scale.

Offset —

Offset returns the offset of the y-scale.

Multiplier —

Multiplier returns the multiplier of the y-scale.

error out —

error out contains error information. This output provides standard error out functionality.

Before you use the PDE Rendering VI, use the PDE Solver VI to solve the equation.

The following block diagram illustrates how to set the scale offset and multiplier of PDE Plot by X Scale and Y Scale.

If you do not set the scale offset and multiplier, LabVIEW uses the default settings of the intensity graph.
