Transient, Turbulent Flow Analysis with SimScale

With the latest update of the SimScale Early Access Program transient, turbulent flow analysis is now possible. Find a little sneak peek what it means to set up such an analysis on the SimScale platform in the pictures below.

How to Perform a Transient, Turbulent Flow Analysis?

Starting off in the Mesh Creator tab we use the boundary layer refinement meshing strategy to create a tetrahedral volume mesh with a refined prismatic boundary layer for the example pipe. With this mesh we can create a new simulation within the Simulation Designer.

Setting up the simulation step by step we choose the necessary parameters, apply initial and boundary conditions that are instantaneously highlighted within the 3D Viewer as shown in the screenshot below.

Once we went completely through the simulation designer tree the simulation is completely specified. We choose an 8-core system for the computation of this analysis and start the simulation.

A few minutes later we get the notification that the simulation is completed. Therefore we can switch to the Post-Processor tab to visualize the computed result fields, apply filters to it or just download the results.

The screenshot above shows the computed pressure field in the pipe which had two different inlets.

Since transient, turbulent flow analysis can be very resource intensive, the scalability of the SimScale platform is a big advantage – you are free to run an arbitrary number of simulations in parallel on the hardware of your choice.
