Aerodynamics

XFlow is able to compute aerodynamic loads over complex geometry, including the effect of rotating wheels and moving parts. It is possible to analyze overtaking or dynamic systems such as the vehicle suspension through a co-simulation with external Multi-Body Dynamic (MBD) software.

The virtual wind tunnel module of XFlow includes a moving ground option and enables users to setup simulations in record time.

 

 

Acoustics

The reduction of aerodynamic noise levels in vehicles is one of the major challenges of the automotive industry. XFlow performs such simulations directly, computing pressure wave propagation instead of modeling the radiation propagation of such waves.

XFlow has also been very well validated by customers for aeroacoustics analysis of the flow through open windows or flow around side mirrors. Additionally, XFlow provides many acoustics post-processing features such as FFT, PSD, SPL, windowing, signal filtering and band-pass filter pressure field visualization which allow a full acoustic analysis to be performed inside XFlow.

 

 

Water Management

The Free-surface solver of XFlow allows water management analysis to be performed, such as flow inside the rain chamber, refueling process, tank sloshing or a drive through of a complete vehicle with real rotating wheels.

The adaptive refinement of XFlow dynamically refines water splashing areas while saving elements on other more stable regions, reducing overall simulation time.

 

 

Internal Flow

Under hood aerodynamic flows or internal air circulation inside the car cabin can be easily simulated using XFlow through a straightforward workflow. The particle-based approach avoids the time-consuming traditional meshing process.

Moreover, the particle-based method of XFlow allows under hood analysis with many complex, arbitrary moving geometries and porous media to be performed, skipping the long meshing process usually required to prepare such simulations.

 

 

Powertrain

XFlow is already used by leading powertrain manufacturers for lubrication applications, mass flow distribution through rotating shafts and gear torque prediction thanks to its multiphase solvers that accurately solve the interaction between any two immiscible fluids.

The particle-based approach of XFlow allows the traditional mesh issues faced in the powertrain complex fluid domains to be avoided, such as perfect contact between moving gears or heavy defeaturing of real geometry . XFlow easily handles perfect contacts between real unsimplified moving gears without any specific preliminary preparation.

Moreover, the FMI standard is implemented in XFlow which allows co-simulations with any external CAE software that supports this standard to be run.

 

 

Thermal Analysis

Vehicle internal heating, ventilation or air conditioning are simulated through the thermal capabilities integrated in XFlow. These capabilities allow both thermal convection in the fluid and thermal conduction inside solids (Conjugate Heat Transfer) to be solved, which are very well suited for engine cooling analysis applications.

XFlow provides a complete set of thermal boundary conditions which enable the user to set up a variety of scenarios. The thermal post-processing capabilities are very complete and allow the engineer to analyze the results in XFlow or export thermal data for further analysis or coupling purposes with third party software.

Is it a plugin or program ?

 

I would say its a stand alone software!

then , how does it works with c4d ?

is there integration for c4d ?

I really dont know, never had chance to use it. It would be interesting to see it in action for sure. :)

thanks for reply ,

for sure I don't work with this kind of work , but it would be nice if it is compatible  with c4d :)
