1. Select Solver/Suspend in the Menu Bar in order to suspend the computation and to check the “solution” in CFView before starting a longer calculation
2. Create a new computation and select it
3. Change the Initial Solution type to from file - Open the run file of the computation suspended before.
4. Deactivate the FMG option - Start the flow solver

Convergence HistoryConvergence History
Convergence Criteria
Global ResidualImage of the evolution of the calculation on the whole domain starting from the initial solution (global residual reference set at 1). To decrease the level of the Global Residual to 3 order of magnitude and to reach a level of Global Residual is also recommended.
Block ResidualImage of the evolution of the calculation on each block for each equation starting from the initial solution (residual reference set at 1). To decrease the level of the Residual to 3 order of magnitude and to reach a level of the Residual in each block is also recommended. Nevertheless, some differences may appear between blocks due to their respective mesh quality.
Mass FlowThe most important criteria to respect. Due to the discretization, 0.5% of error may be accepted between mass flows. Furthermore, both mass flow profiles have to present at convergence no more oscillating aspects.
Local ValueFINE provides the capability to check pressure, velocity,… evolutions locally in the flow field iteration per iteration. Convergence is reached when the evolution isstabilised. If some oscillations are still present in the evolution, the amplitude is defining the quantity precision or natural “unsteady” aspects.
Global ValueFINE provides the capability to check global quantity evolutions in the whole flow field iteration per iteration. Convergence is reached when the evolution isstabilised. If some oscillations are still present in the evolution, the amplitude is defining the quantity precision or natural “unsteady” aspects.
