Hi all,
I'm pretty new to cfd modeling, but am currently trying to obtain a residence time distribution for a CO2 tracer in air inside a flowtube. I am using a piecewise scalar boundary condition at the inlet (diffusion coeff = CO2 in air) to simulate a 10 second pulse of CO2 into the flowtube. I am then tracking bulk results for the scalar on the outlet plane over time.
For some reason, I am getting a very different distribution after switching between CFD 2014 and CFD 2015, even though the mesh, boundary conditions, and solver setup seem to be identical. I have also compared the default flag settings for both and they appear to be the same.
I'm looking for suggestions for other settings I should check, or other defaults that might be different for the two versions.
Thanks.
Hi!
Are you able to share your 2014 & 2015 support share file so we can see what you were doing?
Thanks!
Here's the link to the folder containing the support share files: https://www.dropbox.com/s/5ybd1qclng3z8qq/Autodesk%20Share%20Files.zip
The 2014 version is called Flowtube_D_A and the 2015 version is Flowtube_D2_2. Let me know if you need anything else.
Thanks.
