Hello, i'm simulating a combustor(attached First and cross sectional mesh) via FLUID FLOW(CFX) as u see its only a one forth of a combustor, because my computer too weak to calculate full one. So basically i used CCL from CFX tutorial 30. Coal Combustion. Also domain, boundaries and solver controls were taken from the tutorial, i only changed Mass flow rates in inlets. I'm doing this for my university and gonna make a presentation comparing my results with the tutorials. I seem to get error:
****** Notice ****** |
| A wall has been placed at portion(s) of an OUTLET |
| boundary condition (at 35% of the faces, 15.8% of the area) |
| to prevent fluid from flowing into the domain. |
| The boundary condition name is: Outlet_bot. |
| The fluid name is: Gas Mixture. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead

To note that i use low quality mesh because i need faster calculations to check results and compare, but when i have everything ready i'll calculate with a good one. This Notice disappears after 10 iterations. So now my task is to change Inlet Coal to Inlet Biofuel. I've been searching to find good proximate/ultimate analysis of a biofuel material but i can't seem to find it or because english isn't my first language i seem to not understand which information belongs to particular option or fraction. So has anyone used biofuel in simulation or have all the information to put in ansys, doesn't matter which biofuel, i might need even more than one to also compare results. Also i'm not very skilled on ansys and i think there are mistakes made so if anyone is interested in making some money i can pay for helping me completely finish this project, if that interests you contact me on skype: r4ynal
thank you!

Ye i've read it already, as i said the message disappears after 10 iterations so its not a problem for me. The first time i had this message it was permament in all iterations, i've made changes to geometry to the point where i am now, so i don't really mind having this notice as long as it dissapears and i still get proper results.

What i now want to do is set biofuel or find a person who could help me for a certain price
