Uncrewed Vehicle CFD

Vehicle Design and Analysis

TotalSim is a leader in computational fluid dynamics (CFD) simulation. Our experience helps you accomplish the research and development process at a quicker pace for a successful design. We help you through the whole process: from the initial design where multiple ideas need to be analyzed quickly, to optimizing a design towards the end of the process and gain that last bit of top-notch performance.


Our strong background in the automotive and motorsports industry has positioned us to be a leader in the market. The automated processes we have developed allow us to return results quickly and efficiently saving you time and money in the long run.



Our experience in the UAV industry and with propeller design allows us to help clients from small to large. We excel at numerous aspects of the aerospace market including Reynolds number flows, boundary layer transition models and propeller/rotor design.



In the electric vehicles industry, efficiency is of the utmost importance especially when developing electric vehicles. We use simulation to evaluate a marine vehicle efficiently and effectively find the best solution.

CFD Capabilities:

Depending on the unmanned vehicle, any of the following may be needed to optimize the design.

Fluid Dynamics

Aerodynamics, hydrodynamics, compressible flow, internal and/or external flow, modeling techniques such as discrete element modeling, dynamic moving mesh, free surface modeling or mutli-phase flow.

Noise & Acoustics

Noise can become a problem if it is a nuisance to the community at large. Evaluation to find sources of the noise and then evaluation of options to mitigate it are invaluable.

Propeller/Rotor Analysis

Improving rotor or propeller efficiency can extend range. Analysis can be done with lower order methods but more complicated methods including moving mesh may be necessary.

Thermal Modeling

Thermal management for ICE or electric propulsion systems may be of interest. Modeling of internal and external flow can inform the thermal loads on the unmanned system.

Performance Mapping

Performance mapping is used to define an entire performance envelope. This might be necessary to know how the vehicle behaves no matter what speed or attitude. These results can also be used to inform simulators for performance accuracy.


At TotalSim, we’re solver-agnostic. While we promote free and open-source when possible, we believe in using the best tools for the job. We have experience with nearly all of today’s best solvers, including OpenFOAM®, Star-CCM+®, Fluent®, FUN3D, CFD++® and more.

From consulting to industry applications, tap into our decades of hands-on expertise to simplify your most complex CFD challenges. Complete this form to get started.
