Functions & Formulas

Overview

This section explains how to write node formulas in the Function Editor: how to reference node values, combine them with operators, and use functions to calculate across multi-dimensional data.

Use this section to learn the core formula conventions and find the right function for your modeling task.

Start here if…

• You’re new to formulas and need syntax conventions → go to Formula basics

• You need the most-used functions → go to Quickstart: 10 common functions

• You want to do a simple calculation or condition → go to Operators

• You know the function name (or want to browse what exists) → go to Function catalog

• Something behaves unexpectedly → go to Troubleshooting guide

Who this section is for

This section is for users who work with formulas in the Function Editor, such as modelers and reviewers.

If you mainly work with simulations and do not build or edit the underlying models, go to Simulations & Analysis.
