Tutorial: How to perform a fluid analysis on a simple manifold using Inspire Fluids
Altair EmployeeThe purpose of this article is to provide more details on the steps described in the attached video showing the above-mentioned workflow.
To begin with this article, it is important to mention that this is an easy introduction to the Fluids Analysis included in Inspire. In the same way, the model used in this tutorial is in the Demo Browser. The user can access this by clicking on View > Demo Browser or with F7.
This model is a one piece model and can therefore be referred to as the Fluid Domain. In addition, Inspire is a very visual and colour-coded tool to guide you through the steps. For instance, the Fluid Domain is displayed in red when it is detected. At this point the fluid can be selected or created if it is not in the database. Then, the selected domain fluid is shown in blue when exiting the tool, which means that it has been created and assigned. This step can be confirmed in the Construction History menu (F6).
The following step is to add the Inlets and Outlets on the Domain fluid created. In this example, this manifold will have 1 Inlet and 3 Outlets.
One of the parameters that can be added when creating an Inlet is the Average Velocity. In this case it is necessary to specify the values of velocity and temperature. By other hand, the pressure in the Outlets must be specified.
In addition to this, Inspire Fluids works using voxels when generating the mesh. Besides, the size and number of voxels can be changed manually by entering specific values or by dragging the slider to increase or decrease the voxel resolution.
Continuing with this workflow, convergence plots are displayed when the analysis is running. There are both Average pressure and Average velocity plots. These plots show the convergence for each Inlet and Outlet declared.
Finally, when the analysis has finished running, pressure and velocity results can be observed in the Domain Fluid. Moreover, the flow lines can be animated to observe the behavior of the fluid.
To sum up, this tutorial allows to have a first approach to the fluids analysis in a very simple way in order to understand the workflow, tools and which are the results that can be obtained.
