Hi

first I'm not good at english writing. I 'll apologize about it.

But I really need help...

I'm studying about coal combustion (injection type)

And I used DO(radiation) option, and K-epsilon (viscous)...

But everytime I try iteration,

this error message coming

<turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 19682 cells>

It make me crazy.

what is wrong to this Fluent setting?

please help me

please~~~

Hi.
you can set it's maximum value to higher one at: SOLVE>CONTROLS>LIMITS...
and it may come true at further ittarations!
good lock.

thank you momech, I'll try your method. thank you thank you

[tirtha]

better you should try to alter the default values of VISCOSITY, THERMAL CONDUCTIVITY AND DENSITY of the mixture template you have created

what model your using in modelling "species transport" or "non premixed model"

I already used species transport.

Now I used patch option and limit option~ etc...

so my situation is more better

But thank you for your reply.

thank you
