This is useful in situations where the flow field is non-uniform along the circumferential direction. The Sliding Mesh method is for more complex applications that do not fall under the specific requirements for the Averaging method.
#Solidworks flow simulation boundary conditions software#
The software will calculate the flow fields outside of the rotating reference frame and then transfer them to the rotating region at the boundary. The local rotating region requires that you specify a separate component that includes all the rotating components. This greatly increases the amount of applications where rotating reference frames within SOLIDWORKS Flow Simulation can be used. The local rotating region is very similar to the global except here you can specify a subset of components within the assembly that can be part of the rotating region. If the case comes up where all components are symmetric about the rotational axis but there is a stator (components that are not rotating), stator faces can be specified through the use of a moving wall boundary condition. The global rotating region assumes you have a model that is completely symmetric about the rotating axis and all the components within the computational domain are rotating at the speed of the rotating reference frame.ĭue to the fact this type of rotating region has such narrow requirements, this type is often not suitable for most applications because most industrial applications have components that are not rotating or are not symmetric about the rotational axis. Both of these types are available for all fluid types Newtonian and Non-Newtonians fluids. There are two main types of rotating regions in Flow Simulation global and local rotating regions. This article is meant to be a comprehensive guide to everything related to rotating region problems within SOLIDWORKS Flow Simulation. This will include explaining the different types of rotating region problems as well as the best practices associated with each one of them. There are a lot of capabilities within the tool but, often times, there isn’t a lot of information about these capabilities. SOLIDWORKS Flow Simulation offers some great tools for analyzing rotating region problems.
