Fluid Scenario Creation

Fluid Scenario Creation enables you to define all the required scenario components for a fluid mechanics simulation. This app is suitable for engineers who perform routine fluid calculations to guide iterative design modifications.

Fluid Scenario Creation is a native app that enables you to create and manage:

  • Mesh parameters and material assignments
  • Fluid physics for the simulation, which defines the energy equation used and the turbulence model that describes the fluid flow in the analysis
  • Procedures (for example, steady-state flow and transient flow steps) that configure the analysis type and sequence of steps
  • Initial conditions, such as initial temperature and initial velocity, that describe the base state of a fluid simulation
  • Interactions that specify the flow of thermal energy between surfaces in your model
  • Flow conditions (for example, walls, velocity inlets, and pressure outlets) that define fluid flow and thermal behavior at the boundaries of the fluid domain
  • Volumetric heat sources that define a distributed heat flux over a body
  • Loads that represent concentrated or distributed tractions applied to the model from an external source
  • Output variable requests that control the results data generated by the simulation

Before you begin using Fluid Scenario Creation, you must define the modeling components using the Fluid Model Creation app. In a typical workflow, the modeling components include the fluid domain, material assignments, and fluid and solid sections for the geometry.

Once you have run your simulation, you can use the Physics Results Explorer app to generate graphs and reports, to share your results, and to make decisions on the model design.

SIMULIA also provides test cases and verification information in the CFD Verification Guide, which is available for download from the SIMULIA Community. This supplemental guide contains a series of test cases for the Fluid Model Creation and Fluid Scenario Creation apps that provide evidence that the implementation of the numerical model produces the expected results for one or several well-defined options in the code. The test cases are sufficiently small that you can run them efficiently, but they produce results that you can compare to independently calculated solutions or experimental results.
