Flow Simulation Error Using rhoCentralFoam
Causes and Possible Solutions
Summary
Users attempting to solve flow over simple shapes using the RAS model with rhoCentralFoam have reported encountering a negative error. Investigations should begin by verifying the setup by running the simulation with lower inlet mass flow rates. If the error persists, further troubleshooting may be necessary.
Troubleshooting
Sanity Check
To ensure the case is set up correctly, run the simulation with lower inlet mass flow rates. If the error no longer occurs, the issue may be related to the mass flow rate.
Tutorial and Documentation
Refer to the Multiphase jet tutorial case and the official rhoCentralFoam documentation for guidance on using the solver. These resources can provide insights into the proper configuration and use of rhoCentralFoam.
Solver Description
rhoCentralFoam is a density-based solver designed for compressible, transient flow simulations. Understanding the theory and implementation of rhoCentralFoam can help identify potential issues.
