At this point, the simulation is considered converged. As the iterations go on, key parameters are expected to stop changing. With the previously set result controls, it’s possible to assess convergence. You can run multiple simulations in parallel, only changing the flow rate (in the velocity inlet boundary condition).įor more information about pump curves, please check out this blog post. With SimScale, it’s easy to get the pump curve for your geometry.

SOLIDWORKS FLOW SIMULATION PRESSURE ISSUE HOW TO
We will have a look at this later in the tutorial, so let’s see how to set them up first:įor this simulation, please set a Forces and moments control to the impeller as demonstrated in the picture below: Hence it is an important indicator to evaluate the quality and trustability of the results. Result control gives you the opportunity to observe the convergence behavior at specific locations in the model during the calculation process. This enhances stability for velocity-driven flows, especially in early iterations. In Simulation control, enable Potential foam initialization. If you are a simulation expert, however, you can have a look at them and change the settings as you like. 2.4 Numerics and Simulation Controlĭon’t worry about the Numerics settings, as their default values are optimized according to the chosen analysis type, hence valid for the majority of simulations. This article provides more information about the difference between MRF and AMI Rotating Zones. If we were calculating a transient problem, we would need to choose AMI Rotating Zone. MRF Rotating zones are chosen in this simulation, because we are running a steady state simulation.
