openLCA allows you to include many different functions, operators and constants in your models. For example, you can use formulas and parameters at the “amounts” in exchanges (input/output table in processes).

Sometimes these formulas become complex. For that you can use the Formula Interpreter, which you can find under Tools > Formula Interpreter:

You can see all the capabilities of functions for openLCA in this document. You can also always find this information handy in our openLCA Manual.

Understanding these formulas can enhance your efficiency and accuracy in modeling environmental impacts. For example, you can utilize mathematical constants such as pi for your calculations. Operators in openLCA are used to performing arithmetic and logical operations. Especially, functions, such as if clauses, are useful to perform mathematical and logical operations.

More guidance on how to use this feature is accessible by opening the formula interpreter in openLCA and typing “help” in the command line, as seen above.
