I've been using Boolean operations to subtract the blade portion from the domain. Surprisingly, I noticed that ANSYS automatically considers the subtracted region as fluid, even though it started as a solid geometry. This automation led me to ponder where the software recognizes a void or fluid region and why it makes this automatic assignment.
I followed the same steps as outlined in ANSYS courses, which typically result in the blade portion being subtracted without leaving a void region behind. However, it appears that ANSYS is handling this process slightly differently than I expected.
I'm reaching out to the community for insights or experiences you might have regarding this automatic assignment of fluid properties to subtracted regions in ANSYS. Your knowledge and expertise would be greatly appreciated as I continue to explore this phenomenon.
Thank you for taking the time to read my message, and I look forward to your input.
