Metacomp's CFD software suite CFD++ is widely used by aerospace community globally and in India.
One common observation made by existing customers in India is about the rapid convergence that could be realized. For example, convergence can be achieved for a typical external flow field past an aircraft in about 500 iterations. This means that for a an approximately 7 million cell mesh, utilizing about 100-200 cores, NS solution can be converged in tens of minutes.
If you have a case with mesh that you would like to test its convergence with CFD++, feel free to contact Metacomp's support at support_india@metacomptech.com
