Finite Element Methods For Computational Fluid Dynamics A Practical Guide

Looking at the example: the user converted "open-source" into three variants. So if "open-source" is part of a software name, but in the given text, it's not. The first sentence is "An open-source software package for CFD...", which is a description of the software package, not a proper noun. So "open-source" here is an adjective and should be converted. Therefore, "Finite Element Methods" in the conclusion might be a common noun phrase and should be converted unless it's a proper noun term. However, in academic writing, "Finite Element Method" is a proper noun referring to a specific method. So perhaps it's a proper noun. But the user's example did convert "Finite Element Methods" in the conclusion. Wait, in the user's original text, after the conclusion, they have "FEM provides...". So perhaps the user wants "Finite Element Methods" to be converted into "FEM|FE Methods|FEM Methods"? But the task is to convert every word with three variants. Wait, no. The user says to convert every word with three variants as word1. So each individual word in the phrase "Finite Element Methods" should be converted unless the entire phrase is a proper noun.

Wait, the user wants three variants for each word. Let me check each word again. Looking at the example: the user converted "open-source"

For instance, in "CFD books by Frank M. White," "CFD" is a proper noun (the abbreviation), so I'll leave it. "books" would be converted, "by" would be left as it's a preposition (but wait, prepositions might need conversion if they're not part of proper nouns. However, the user's example might not have included prepositions, but the task says "every word" so maybe prepositions should be converted. Hmm, the user says "convert every word with 3 variants as word3. Don't touch proper nouns." So prepositions like "by" might need conversion. For example, "by" could become through.

"Finite Element Methods are a powerful tool for simulating fluid flows and heat transfer in various engineering applications."

Proper nouns like COMSOL, ANSYS, and the books (Hughes, 2000; Donea & Huerta, 2003) should be left untouched. Also, the years and titles in the references are proper nouns? The book titles might be in italics in the original but in the given text, they are in quotes. So "Finite Element Method: A Practical Guide" would be in quotes. So the title is a proper noun and should be left as is. The software names are proper nouns.
