I have been trying to figure out an issue where a simulation runs well when accounting for cavitation via two phase flow. However when I was trying to run the simulation with only the fluid phase I started to encounter a bounds error with the turbulence eddy frequency.

The error is listed below.


Bounds error detected

---------------------
Variable: Turbulence Eddy Frequency
Locale : Psupply

+--------------------------------------------------------------------+
| ERROR #004100018 has occurred in subroutine FINMES. |
| Message: |
| Fatal overflow in linear solver. |
+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 1. No results file |
| has been created. |
+--------------------------------------------------------------------+

Does anyone know what the difference is between the single phase and multi phase turbulence equations that is causing this or have any ideas on how to fix it.

Also does anyone know how to plot the residual values in the cells in CFXpost so that I can know where the mesh is having trouble?

That is in the documentation - but is unlikely to be a useful path forwards. A more useful path is likely to be this FAQ: https://www.cfd-online.com/Wiki/Ansy...do_about_it.3F

To put the residuals in the res file so you can view the distribution of residuals: In CFX-Pre, go to the output control and in the results tab: select "Output Equation Residuals" and select "All".
