"Avolie" does not appear to be a widely recognized term or concept based on my training data up to October 2023. It’s possible that you might be referring to "avoli," which typically means "grooves" or "furrows" in some contexts, but without more context, it is difficult to ascertain the exact function or meaning you're asking about.
If "avolie" refers to something specific within a particular field (like biology, technology, or another area) or a specific product or brand, please provide more context so I can assist you better.
