Global GT-SUITE Service Providers

Expert Simulation service providers GT-SUITE

Gamma Technologies frequently receives requests from companies who wish to outsource GT-SUITE simulation projects.  While we are pleased to receive such requests, GT’s primary focus has always been on providing the best and most advanced simulation software, rather than on consulting services.  For this reason, GT refers such requests to professional consulting firms.  It is in this spirit that we have established the “Consulting & Services Providers List” program, listing high quality consulting firms experienced in the use of GT-SUITE, which have built long term relationships with Gamma Technologies.

Powertrain Technology (PTL) are a team of experienced, multi-disciplined and creative professionals, highly skilled in design, analysis, development and procurement of turn-key engine and machinery projects. As independent engineering consultants we combine our simulation expertise with our extensive experience of materials, manufacturing and production techniques, coupled with a proven track record of innovation.

PTL applies GT-SUITE to:

  • Engine Performance modelling and acoustics
  • Cranktrains, Valvetrains, bearings and other mechanisms
  • Vehicle simulation – Conventional, Hybrid and Electric
  • Cooling & lubrication systems and fluid networks
  • Fuel Injection systems and other fast electro-hydraulic systems

Multi-physics Specialists – PTL can create high fidelity models of physical hardware for faithful replication of response to changes in design parameters and operating conditions. By leveraging GT-SUITE multi-physics capabilities we can model complex interactions and feedback loops which can occur and often affect the performance, transient operation and durability of engines and machinery. Other 3D packages, like CONVERGE and ANSYS, are often employed in co-simulation or as a mean to calculate specific GT-SUITE modelling parameters.


MAHLE Powertrain delivers engine engineering and manufacturing services as a powerful complement to our customer’s own activities. From initial concept, through design, analysis, development, calibration and testing to prototyping and series production, we provide the complete value chain with extensive knowledge and experience.

MAHLE Powertrain has extensive experience of GT-POWER for performance simulation, specializing in performance and fuel economy optimization of both naturally aspirated and boosted engines, such as our downsizing demonstrator engine.

Vehicle dynamics and drive cycles of both conventional and hybrid vehicles are modeled using GT-SUITE for vehicle simulation (previous GT-Drive) and GT-SUITE for Valvetrain simulation (previous GT-Vtrain) is used in the development of new valvetrain components.
