Potential

Allows for creation of arbitrary scalar potentials to represent forces acting in the system.

Input

  • x: A Linear Space called "x" in the expression
  • Scalar: A real scalar called "a" in the expression
  • Scalar: A real scaler called "b" in the expression

Content

The input-field can take any analytical expressions described in the Expressions-page. Within the expression you have access to the variables x, a, and b, where x is the spatial dimension input and a/b are the scalar inputs to the node.
