Hi there,

I was running the incompressible Navier Stokes test case of "Flow over a cylinder". I used a Reynolds Number of 200. I did an unsteady analysis using dual time stepping of 1st order. No Turbulent solver. I ran it in parallel using the python script on 6 cores. It generated output files but the program execution ended with an error message. Am attaching a snapshot of the error message. Kindly look into this and give a solution. Thank you.

Hi there,

P { margin-bottom: 0.21cm; } Am facing another problem with the same test case , but now am using a Turbulent solver - SA turbulent model. Its displaying an error message that "Convective Scheme not implemented". I have tried with ROE solver.

Looking into the Numerical Preprocessing in definition_structure.cpp - it shows that for incompressible euler or NS it has the option of ROE_1st and 2nd.

Am attaching a snapshot of the error with this message. Please look into this and suggest where am I going wrong. Thank you.

It sounds like you may be using a slightly older version.
The quick fix is to use ROE-1ST_ORDER
The longer fix is to update your code to version 3.2.2
