Summary

Polynomial user expression

Description

Provides an expression with the name given by the user_tag parameter using the provided polynomial function. The provided user tag should not include operator, subindex, phase, component, or material phase prefixes or suffixes. See General Naming Convention for more detail about those. The polynomial value, \phi, is calculated as \phi = \sum_i^n C_i (X + X_0)^i where X_0 is the variable offset, X is the variable, n is the order and the coefficients provided are C_i
