Chemistry tab grayed out

MFiX
#1

Hello
Whenever I start a new project, I find that the chemistry tab is grayed out. How can I enable it?

Thanks a lot.

To enable the chemistry pane, you need at least two species defined (fluid + solid).

For example, go to the fluid pane and add O2 and N2. The Chemistry pane will then be enabled.

Thank you very much. I would like to ask if you have got an MFiX tutorial that involves chemical reactions with user defined functions.I coudn’t find any in the user guide.

Thanks in advance
