Ansys Discovery Erfahrungen

With the proper and appropriate hardware, you can obtain a solution significantly faster than conventional solution methods by leveraging the power of GPUs, even older ones. For simple problems (i.e. single parts and/or basic external vehicle aerodynamics), it is very easy to set up.

I'll give what I think are opportunities for improvements based on domain.

Static structural - does not handle multiple parts/complex assemblies very well. Does not/cannot model non-linear contacts. Does not/cannot simulate non-linear materials. Defining and applying custom materials is sometimes quite cumbersome.

Fluids - Cannot extract important engineering values from the fluid simulation, e.g. coefficient of drag/coefficient of lift from the external aerodynamics example. Cannot select other turbulence models. (Last I inquired, you can ONLY use the LES turbulence model, which is invalid for certain types/classes of analyses.) Cannot model air as an ideal gas (compressible flow solver). Cannot define point heat sources.

Direct modelling/manipulation - if you have a part with defined dimensions (part from print), it is quite cumbersome to reproduce the part using the direct manipulation method. Direct manipulation method is great when you are trying to experiment with new designs and you are trying to figure out which design will work best, but if you are trying to test/verify an existing design and you don't have the original/source CAD part, which requires you to re-model it in Ansys Discovery Live/SpaceClaim, it's ridiculously complicated to create, for example, a dimension that is symmetrical/mirrored.

Topology optimisation - Sometimes the result from the topology optimisation does not pass the FEA analysis.

Its a complete standalone software. It doesn't need anything else to function.

It's a complete standalone software. I can't use it on existing simulations, or transfer simulations from discovery directly to fluent / mechanical. If I do I have to redesign everything, remodel everything, reset the boundary conditions and everything

Ansys discovery is a great tool for easy and quick simulation. It offers a streamlined workflow for the user to quickly setup a problem's geometry and mesh, then setup the properties and boundary conditions. In addition, optimization is very efficient as changing the problem's variable is very simple and not time consuming.

Although the mentioned advantages look very attractive, there is a downside for quick and simple simulations. This is of course related to the accuracy of such calculations. It should be kept in mind that this ANSYS Discovery which is mostly targeted for problems not requiring very high accuracy. Other than that, the software sometimes crashes unexpectedly or won't start at all if graphic card requirementw are not met (which are actually very high)

The user interface is very interactive with an heads up display (HUD) that tells you what information is required to complete whatever study(ies) to be carried out and as soon as enough information is supplied, results can be gotten instantly.

Due to its real time nature, performance relies heavily on system GPU so you might need to follow the minimum system requirements. I noticed a restriction on exporting files to only discovery file format.

The 'instant' or 'live' results has some educational possibilities, but is limited by other issues.

The interface is completely unlike and OS or Engineering software suite in use.
When using with SW or CREO, for example into Discovery for analysis, users are completely dumbfounded.

Discovery is extremely limited without a 'full' ANSYS workbench license. If I have the Workbench license, the Workbench UI is cleaner and easier to use.
Symmetry planes, contact types, convergence reports (in my case) 'on the fly analysis' were completely missing.
