In this node, a potential expression can be obtained by combining two potential functions with an arithmetic operation.
The node has the following inputs:
In the content field, an arithmetic operation is defined to combine the two potential functions entered in the Potential nodes.
After all the inputs are provided, the node gives the following output:
An example is shown below where two potential functions are added together to plot the resulting potential.
This allows the user to visualize the system and ensure the potential's correctness if the final potential function is a long combination of many functions.
