"Temperature too low for cell" error message
 

Hi guys,

I'm experiencing an issue while using EDC method with version 18 of Fluent.

I'm forced to use EDC method since the Damkohler number into my domain varies very much. Moreover, I'm using a multi-step kinetic scheme, so EDM is not applicable.

When I use this setup, I get this warning message:

Temperature too low for cell=XXX on thread=YYY at node=ZZZ

And this message is repeated thousands of times.
I noticed that this "reporting" slowed down my run (by monitoring cpu usage of fluent processes).
So, I'm trying to overcome this issue by "muting" these warnings.
When I asked tech support this, they answered me to disable limiter-warnings (solve/set/limiter-warnings off).
But, since this warning is NOT relative to limiters, it didn't solve my issue.

Please, consider that this warning message did never appear in previous versions of Fluent (until 18).

Have, anyone of you, got this issue and found a workaround to overcome this issue?

Thank you for your time.

I am facing same problem with fluent 18.2

This type of message can also appear when a cell temperature outside a property curve (specific heat for example).
