On the issue of defining unconventional components
Thread Content
I want to simulate coal powder combustion, and I also defined an unconventional component, coal (mainly based on the elemental analysis of coal powder); everything was defined according to the instructions in the book. However, the \"component attr\" field in the material flow remains gray, and I’m not able to use the substances I defined myself. What’s going on? Thank you!
Is everything regarding the contents in coal specified clearly? Please be more explicit; that way I’ll be able to define oil successfully
