The AVL FIRE™ Engine Simulation Environment (ESE) offers dedicated solutions for simulating IC engines and engine components.

AVL Approach

Users of AVL FIRE™ engaged in IC engine research and development value particularly a set of tools collected in the FIRE™ Engine Simulation Environment (ESE), supporting them to perform their day-to-day business: the simulation of the flow in IC engines and engine components.

Benefits at a Glance

  • Tailored solutions for most common tasks.
  • Pre-defined workflows providing re-producible, user-independent results.
  • Easy to operate.

ESE Aftertreatment

FIRE™ ESE Aftertreatment comprises newly developed features and functions enabling its user to quickly setup and perform the generation of models for exhaust lines including exhaust gas aftertreatment devices. Within an automated grid generation process the tool takes care about all mesh requirements during subsequent simulations. Setting up a simulation task is based on pre-defined control files. That way the knowledge required about numerical models is reduced to a minimum. The task is now so easy that almost everybody can perform it.

ESE Diesel

FIRE™ ESE Diesel is the first CFD tool to allow all levels of users - beginners, intermediates and experts - to set up, simulate, analyze and optimize aerodynamics, fuel injection, combustion and emission formation in diesel engines. A fully automated meshing process accounts for the generation of a moving mesh data set including a specific, non-changing topology for the spray domain, a defined number and thickness of boundary layers and perfect adjustment of the compression ratio. Pre-defined simulation control files avoid effort on numerical model selection and parameter identification. Simulation results are automatically analyzed and translated into engine specific performance parameters.

ESE Engine

FIRE™ ESE Engine is a largely automated grid generation tool enabling fast and reliable creation of high quality models for in-cylinder flow simulation. The topology of the grid to be generated is defined and manipulated by the user directly interacting with the software. The software delivers an immediate visual response on all user actions enabling the engineer to react whenever desired or necessary. ESE Engine is faster than many fully automated tools and much faster compared to approaches which rely on pre-defined start topologies. On top of that ESE Engine is the only IC engine pre-processor that allows wrapping the computational grid with an arbitrary number of high quality boundary layers of a user-defined thickness. That way the highest simulation accuracy is ensured for both flow and heat transfer calculations.
