We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thank you so much.

So instead of using mass source, I will be using scalar sourcem right?

If so, I think we may need to change step 5 in the pdf file mentioned above. 

5. Under Source Terms, enable (Mass) sources and specify the fluid density (If the density varies by location, you can use a UDF).
