species transport model

skumar112 · April 25, 2017, 10:22

Hello,

I am running a species transport model to model the combustion in a compressible jet. However I am getting some oscillating residuals. I have refined the mesh, but it hasnt helped. I am monitoring the solution values at points within the computational domain and they seem to be oscillating as well. I have reduced the under-relaxation factors and set the solution to first order wherever possible. I would really appreciate the help

Did you ever figure this out ?
