MantiumCAE new CAESES Channel Partner & Last KVRC Race

Posted on 5. November 201516. October 2018 by Press

Mantium^CAE is proud to announce being a new channel partner for CAESES for the DACH region.

CAESES is a great software to parametrize complex geometries in a very efficient way.
The parametrized geometries can subsequently be used to execute DoEs or optimizations, as CAESES couples with many CFD products like XFlow or OF.
This homepage will be updated soon. For more information, please visit the official homepage, where it is even possible to download a free version of CAESES. Please contact us for more information.

Rear Wing, created with CAESES

Also, it is time for the last KVRC race, in which Mantium^CAE is competing with the virtual racing team Mantium^RAY.
The new car was mainly developed using CAESES. In previous races, it was for example used to generate wing profiles, which were used to create the rear wing by means of a simple straight extrusion. For this race the wing was also parametrized along the wing span. This should be a key element of bringing Mantium^RAY back to the very top of the podium.

Parametrized rear wing

The optimization showed that wings with good lift to drag values could not create the necessary levels of down force to balance the car. But as the new rear wing showed to be elegant and efficient, the car had to be balanced again. As the car had also been fully parametrized and run through a DoE, lots of data was available to balance the car using analytical methods. This showed to be very difficult, as every parameter that shifts the balance further to the rear was detrimental towards the other important performance factor: Lift / Drag. The following plots show this trade-off for the rear wing height:

Carefully using this data, the car was balanced and now reaches new levels of performance. Below are images of the new car:

KVRC – MantiumRacer for Monaco

Posted on 17. May 201516. October 2018 by Press

With the KVRC Monaco race coming up, we present the new MantiumRacer.

Unfortunately it has not seen the Mantium treatment yet. So the car has now mainly been developed using conventional methods.
The car will get much closer to the podium but will probably, at best, reach the third position.

Some parts are carry-over from the first race. Many others have been redesigned. On the first car the considered options for the cooling outlets were above the floor or behind the rear wheels integrated with the fender. Both affected downforce negatively but shifted the lift balance in a favorable way. Now the cooling outlet is integrated behind the drive train together with the main body. This showed to be aero-neutral. Also the exhaust was integrated into the newly designed diffuser. Having the exhaust here gives some gains in downforce. Other positions resulted in detrimental downforce values. Also the front has been redesigned with a low nose and a larger three element front wing. Shifting the side-mirrors further outward resulted into significant gains in downforce and lift balance. After the large front wing the air has quite some trouble to reattach to the car and create a nice clean air flow to the rear wing. Having the side mirrors in this area did not help too much, so now they are located in a less critical position.

As first optimization work has been carried out though, some results of the rear wing will be shown. Below are results from optimizing the rear wing profile. As the base design of this wing profile was already so good the downforce coefficient could not be improved any further. There are some designs with a better efficiency at lower downforce values. These wing profiles might come in handy at later races which require less downforce but more aerodynamic efficiency.

New Homepage & KVRC 2015

Posted on 14. April 201516. October 2018 by Press

Mantium^CAE is proud to present the new company homepage.

Please feel free to have a good look around.

Also we have entered the KVRC Challenge 2015. It is a virtual challenge to design a Le Mans prototype vehicle.

The first race was last weekend. Unfortunately Mantium^CAE did not reach the podium.

Now it is time to use the tools available here at Mantium^CAE like XFlow and OpenMDAO to develop a car with a more pleasing and competition crushing performance.

We will inform about the methods and progress on these pages.
