All Things Ansys 084: The State of Mechanical Meshing in Ansys 2021

 

Published on: March 22nd, 2021
With: Eric Miller & Joe Woodward
Description:  

In this episode your host and Co-Founder of PADT, Eric Miller is joined by PADT’s Senior Mechanical Engineer and Lead Trainer, Joe Woodward in order to discuss what new mechanical meshing capabilities are available in Ansys 2021.

Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain. The mesh influences the accuracy, convergence and speed of the simulation. Furthermore, since meshing typically consumes a significant portion of the time it takes to get simulation results, the better and more automated the meshing tools, the faster and more accurate the solution.

The State of Mechanical Meshing in Ansys 2021 R1 – Webinar

Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain. The mesh influences the accuracy, convergence and speed of the simulation. Furthermore, since meshing typically consumes a significant portion of the time it takes to get simulation results, the better and more automated the meshing tools, the faster and more accurate the solution.

Ansys provides general purpose, high-performance, automated, intelligent meshing software which produces the most appropriate mesh for accurate, efficient multiphysics solutions — from easy, automatic meshing to highly crafted mesh.

Meshing in the New Ansys Fluent Task-based Workflows

Working with a variety of users with different levels of CFD (Computational Fluid Dynamics) backgrounds, I have to admit that Fluent meshing used to be a challenging and confusing task for beginners and even intermediate users.

Ansys has addressed this challenge by redesigning the Fluent user interface to provide a task-based workflow for meshing that enables engineers to do more and solve more complex problems than ever before in less time. The new Fluent task-based workflow streamlines the user experience by providing a single window that offers only relevant choices and options and prompts the user with best practices that deliver better simulation results.

Best practices are embedded into the workflow in the form of defaults and messages to the user. This reduces the amount of training required to start using the software and makes it easier for occasional users to return to the software.

How to Mesh Watertight CFD Geometry in the New Ansys Fluent Task-based Workflow

In order to use this workflow, you need a relatively clean watertight solid and/or fluid regions that can be meshed by surface meshing and then volume filling (no wrapping required.) Geometry can consist of single or multiple bodies.

Going through the task-based workflow is straightforward. You are presented with several steps, like:

  • Surface mesh.
  • Describe geometry. (Fluid and/or solid)
  • Capping. (If you are creating an internal flow volume, then the capping tools in Fluent makes extraction easy)
  • Volume meshing. (If you wish to use the latest Mosaic meshing technology, select “Poly-hexcore”)
Mosaic Meshing Technology

Now, click on “Switch-to-Solution,” to bring the mesh into a familiar Fluent interface.

Fault-Tolerant Workflow for Ansys Fluent Meshing Wraps and Seals Leaks and Gaps

Sometimes CFD simulations contain dirty, non-watertight geometries. For instance, 3D scanned or manufacturing geometry files. These geometries may contain missing faces, gaps, holes, overlaps, and other issues. As a result, they require extensive cleanup before simulation.

To overcome this obstacle, Ansys offers a new Fluent meshing workflow that wraps dirty geometry without cleanup.

The workflow for non-watertight geometry offers distinct advantages over other meshing technologies such as:

Part management:

Users can perform CAD-level changes to any geometry or assembly, including dragging and dropping objects from the CAD model into the simulation model.

Leakages and overlaps:

The fault-tolerant workflow seals leakages caused by gaps and misalignments between solid bodies. This significantly reduces the manual efforts required to clean up geometry.

The fault-tolerant workflow can easily wrap leaky geometry

STL file input

The workflow can create fluid regions directly from STL files or scanned data. This eliminates the need to convert STL files into solid geometry for the biomedical, oil and gas, automotive and other industries.

Imported STL File

2020R2 updates:

There are a few important improvements both in Watertight meshing (WTM) and Fault-Tolerant meshing (FTM) workflows in the 2020R2 release.

FTM/WTM: Wild card selection in lists

The Meshing Workflows now have an option to use a persistent Wildcard string for selecting labels or zones. This is in addition to the Filter Text option previously available. The new Use WildCard option stores the wildcard string itself in recorded workflows instead of an explicit list of locations so that when they are played back with new geometries, the matching will be performed again and pick up any matching zones/labels that were not in the earlier geometry.

WTM: Support of Region-specific Sizing 

You can specify region-specific Max Size and Growth Rates during the Volume Meshing task.  If you enable Region-based Sizing, Fluent will compute default sizing specifications for each region.  These can then be adjusted as required for each region.

WTM: Start From Imported Surface Mesh

This is useful if you have an established surface-meshing workflow or if you already have a mesh generated (perhaps from another preprocessor or an existing Fluent case) and want to use that as a starting point for Fluent meshing. Once you import the surface mesh you have the option of using it as it is, or selectively adding additional Local Size controls and/or remeshing particular surfaces as needed.

FTM: Continuous prism layers for Poly and Poly-Hexcore for Fluids

For the Fault-Tolerant Meshing Workflow you can now create continuous prism layers without stair-stepping within poly and poly-hexcore fluid regions.  Note that this will apply in all zones of the region.

WTM: Support of Local Sizing on Labeled Edges

Once you have labeled the edges, you can select Edge Size in Add Local Sizing to prescribe a target size on the selected edge(s).

ANSYS Mechanical: Mesh Time Metric Display

The things you find out from poking around the Enhancement Request list…

Did you know that you can get ANSYS Mechanical to report the amount of time that the meshing takes? I didn’t until I stumbled across this little gem on the request to show mesh time metrics.

This option is already available for many releases now. Users can turn performance diagnostics by setting to Tools -> Options -> Miscellaneous -> “Report Performance Diagnostics in Messages” to Yes inside Mechanical.

So, of course, I tried it out.

This was in version 2020R1, but it says that the option has been there since R19.0.  Now they just need to add it to the Statistics section of the Mesh Details so that we can use it as an output parameter.

Fluent Updates in ANSYS 2020 R1 – Webinar

Computational fluid dynamics (CFD) can be challenging for a multitude of reasons, but not with ANSYS Fluent. Anyone can get great CFD simulation results with ANSYS solutions. Fluent software contains the broad, physical modeling capabilities needed to model flow, turbulence, heat transfer and reactions for industrial applications.
