On the heels of February’s exciting product launch, we announce the first point release for the ANSYS Discovery family of products. Our development team has been hard at work to incorporate customer requests, enhancements and workflow improvements to make 3D modeling and simulation easier for all designers. As much as I’d love to share all that’s new for you in Discovery 19.1, for now, I’ll focus on a few.
ANSYS Discovery Live — Fluids
In Discovery Live 19.1, we’ve expanded the usefulness of specific fluids displays. Users will realize more accurate and robust results that deliver valuable feedback in a shorter amount of time. For example, when measuring pressure or velocity, users will see transient solutions converge (settle down) significantly faster than before. Also, when visualizing velocity using surfaces, isosurface or composite smoke-like view, users will also gain greater confidence in the accuracy and reliability of their simulation results.
A new vector display for fluids combines the detail of flow lines with the animation of particles. Non-time-dependent arrows, which show results faster, give insight into the direction and velocity of flow, while greatly improving the visibility (versus traditional flow lines).
If you’d like to learn more about any of these enhancements, please register for our Discovery Live 19.1 update webinar.
ANSYS Discovery AIM — Workflow
While this release of Discovery AIM offers many workflow and post-processing improvements, the most impressive is the addition of physics-aware meshing. We have automated the manual task of establishing a mesh from the workflow, and integrated it into the physics setup. Based on the type of solution desired and the boundary conditions, Discovery AIM will intelligently create an appropriate mesh. For applications like topology optimization, Discovery AIM creates a uniform mesh throughout, then will automatically refine the mesh and include inflation layers at boundary conditions and contact surfaces to improve the resulting optimized shape.
The same applies to nonlinear contact analysis, where a refined mesh is now automatically placed on the contact surfaces. This saves the manual step of generating a mesh and determining the resolution at certain locations, while simultaneously improving solution accuracy.
For fluids studies, physics-aware meshing automatically generates boundary layers on all walls, resulting in a higher fidelity fluids solution (below).
Users can still utilize the fidelity slider to achieve the desired balance of speed and accuracy, as well as manually define a mesh if more control in certain areas is required.

Discovery SpaceClaim — Shared Topology
If you’ve seen or used Discovery SpaceClaim before, you know how well it manipulates geometry for downstream purposes: manufacturing of designs, reverse engineering scanned bodies, optimizing models for 3D printing and, of course, preparing models for engineering simulation. The shared topology functionality, which is integral for establishing connections between bodies of an assembly, has visualization enhancements that greatly facilitate connecting geometries.
Beginning with an option to preview connectivity by color, Discovery SpaceClaim displays the edges as they would be shared, so users can decide which edges should or should not be shared. If an edge is close to a surface or another edge, but not actually touching, Discovery SpaceClaim will flag it with a color of your choice.
For visualizing larger assemblies with many connections, an obscured edges option displays (in a faded view) all edges that would otherwise be hidden. Similarly, a fade option turns the majority of the visible model transparent and displays only the edges that will be shared.
Learn more about the Discovery SpaceClaim enhancements in a soon-to-be-announced webinar.
Discovery Live and Discovery SpaceClaim — Named Selections
I want to mention one more enhancement that benefits users of all three applications. found in the latest versions of Discovery Live and Discovery SpaceClaim. Previously, it was difficult to maintain a selection of facets after a smoothing or shrink-wrapping operation. Users would have to reselect facets after any sort of editing operation. Now, in ANSYS 19.1, named selections and boundary conditions remain, and the named selections are easier than ever to select. This is particularly useful in Discovery Live when performing a structural simulation on a faceted body. Boundary conditions will remain on a selection of facets, even after smoothed, shrink-wrapped or edited in any way. This allows users to perform simple or drastic changes to a model without needing to redefine the boundary conditions.
