Hi guys

I read the brochure from MSC and as i understant it is a meshfree aerodynamic software, does anyone used it?

i believe that ir needs a lot of time to solve an aerodynamic problem if it is SPH and also it needs high end computers,

so what kind of meshfree method does it use?

My guess is it was derived from their RealFlow product, geared towards visual special effects and animation. And they took that and made it more realistic. So what you get is a software not derived from scientists but artists, kind of. It may turn into something great one day?

It's a very new software with a very small team, thats why they are going that low key. The kick-ass visualization is due parent companies vast expertise in animation.

What I know it that it's quite good in subsonic and transonic regime while in supersonic speeds it's not very well tested.

Note - These are all my personal comments.

Xflow does not use the Navier-Stockes Equation for continuous Fluid Mechanics, it use Lattice Boltzmann method (LBM) and Lattice Gas Automata (LGA) (methods based on a mesoscopic framework) and extends them to overcome most of the limitations present on these schemes.

@ Eleazar: XFlow solves the external aerodynamics with very acceptable engineering simulation time and accuracy. These are transient analysis so they run longer, I run most of my simulations on a standard desktop.

@ Kevin De: Visualization has some background of realflow, however under the hood its a code that eliminates barriers with traditional CFD softwares like meshing, dirty CAD, complex motion problems and solves them with accuracy.

... and the code has some built in intelligence to decide, if a gap or hole in a dirty cad model is there in purpose ...

Hey Joern,

I like the skepticism.
XFlow is certainly a paradigm shift where it eliminates the barriers from traditional CFD of meshing, dirty CAD , complex motion problems.

Some people don't know what they are selling. LBM is usually Cartesian based, so there is a mesh. If someone tells you that, he has not a clue about what he/she is selling to you
