Windshield Wiper Modeling in Ansys Fluent Software (ABP)

This Application Best Practice (ABP) provides a comprehensive guide on modeling windshield wiper performance using Ansys Fluent software and the required methodologies relevant to simulating this application.

Learning Outcomes:

Following completion of this Application Best Practice (ABP), you will be able to set up a windshield wiper simulation including the:

• Utilization of multiphase model transition, for complex simulations involving rain droplets, thin films, and water pools.
• Use of overset methods to simplify the simulation process by avoiding remeshing complexities.
• Application of UDFs to enhance Ansys Fluent's standard features, such as defining grid motion and particle reflection.
• Significance of dynamic mesh settings for accurately modeling the deformation of wiper zones.
• Practical steps for configuring physics settings in multiphase systems to improve convergence and simulation accuracy.

Prerequisites:

• Get Started with Ansys Fluent
• Ansys Fluent Dynamic Mesh Modeling'
• Get Proficient with Ansys Fluent Using User-Defined Functions (UDFs)
• Ansys Fluent Multiphase Flow Modeling

Please note: These training materials were developed and tested in the 2025R2 release.

Application Best Practices (ABPs) outline engineering design goals for specific applications and provide guidance for how to achieve those goals using Ansys simulation software. It is important to note that a Geometry File or other Input Files are not always available. ABPs, as opposed to the official training-material workshops/tutorials, are not meant to be a step-by-step instruction document. ABPs are a link between product-based training courses and application specific tutorials, educating on the "how" and "why" of the best modeling approach, highlighting best practices and workflows for a particular application.
