Ansys 2019 R2 rolled out a new fault-tolerant workflow that simplifies Ansys Fluent meshing of complex computational fluid dynamics (CFD) simulations.
Traditionally, engineers spend a lot of time on geometry meshing. The new workflow accelerates this process and greatly improves the user experience as a result.
In a recent release, Ansys introduced a task-based workflow that sped up Fluent meshing of watertight geometries by 70% — and with 50% fewer clicks.
The fault-tolerant workflow can easily wrap leaky geometry.
However, some of the most important and complex CFD simulations contain dirty, non-watertight geometries. For instance, the geometry used in simulations of automotive front-end airflows, external aerodynamics and complex external/internal flows can’t be meshed using the task-based workflow. As a result, these geometries require extensive cleanup before simulation.
To overcome this obstacle, Ansys 2019 R2 offers a new Fluent meshing workflow that wraps dirty geometry without cleanup.
The fault-tolerant workflow improves Fluent meshing with wrapping. The workflow enables users with minimal experience to generate meshes of complex geometries.
For example, the workflow for external aerodynamics meshing has predefined settings based on best practices.
These settings help users create:
Ansys Fluent fault-tolerant workflow includes wrapper technology that covers and seals leakages and gaps.
The workflow for non-watertight geometry offers distinct advantages over other meshing technologies.
The new Fluent meshing workflow is a significant timesaver. Overall, benchmarks indicate that an engineer experienced with Fluent will see a 2X speedup. The workflow virtually eliminates scripts, manual interventions or pop-ups —making it more accessible and easier to learn.
