Advanced Concepts

SimScale allows its users to model advanced flow characteristics, like rotary zones or porous media, which would otherwise require sophisticated geometries or large meshes leading to expensive simulations. This modeling can be done using the Advanced concepts feature which can be found below boundary conditions in the simulation tree:

The options available for modeling depend on the chosen analysis type. Only the analysis types based on the OpenFOAM® solver support this feature, which are:

  • Incompressible
  • Compressible
  • Convective Heat Transfer
  • Conjugate Heat Transfer
  • Conjugate Heat Transfer v2.0
  • Multiphase

In general, the following choices are available as advanced concepts:

  • Rotating Zones
    Rotating zones can be used to model rotating systems such as turbines, fans, ventilators, and similar systems. Two types are available: MRF (Multiple Reference Frame) and AMI (Arbitrary Mesh Interface).
  • Solid Body Motions
    Solid body motions models the effect of the movement of the solid body sitting inside the fluid domain. This includes linear, rotating, and oscillating motions. A complete ship design analysis and a six degree of freedom simulation are also possible.
  • Porous Media
    With this option, a volume, within the simulation domain, can be modeled as a porous medium avoiding the need for a porous geometry and subsequently a fine mesh.
  • Power Sources
    To model the heat generation from a volume it can be defined as a power source. Power sources can be assigned as either an absolute or a specific value.
  • Momentum Sources
    Momentum sources can be used to simulate fans, ventilators, and other similar devices without having to model the exact geometry and motion of the device.
  • Passive Scalar Sources
    Passive scalar sources can be used to simulate the propagation of species like smoke from a burning car in a garage or the diffusion of dust or pollutants in a tunnel. This is only valid if these species get transported with the fluid without having any effect on the flow physics.
  • Thermal Resistance Networks
    It can be used to approximate the effect of heat sources and heat transfer from that source to the surrounding domain without explicitly having to resolve the source geometry itself.

For Pedestrian Wind Comfort and Incompressible (LBM) analysis types, this feature is addressed as Advanced modelling.
