When it comes to computational fluid dynamics, one of the most widely used software packages is FLUENT. This powerful tool allows engineers and researchers to simulate fluid flows and analyze complex systems. However, even with its vast capabilities, there are still certain challenges that users may face. One of these challenges is related to vacuum modeling within FLUENT. In this blog post, we will dive into this topic and explore potential solutions to this issue.

The equations in FLUENT are based on a continuum flow, what you have is probably free molecular flow. I think in this region it doesn't matter if you have slip boundary condition or not.
