Application: lubrication system of a 4 cylinder engine

Once the description of the 3D CAD system is complete,

the corresponding sketch can be generated in

LMS Amesim with parameters settings automatically

performed.

Application: cooling system of a 4 cylinder engine

The 3D CAD model is constituted of

the engine cylinder block material and

the fluid domain corresponding to the

water jacket.

In order to create a lumped thermal

model, both CAD bodies are split into 4

different bodies that correspond to the

number of cylinders.





For the fluid domain, the heat exchange surface and the fluid ports are

selected.

For the thermal capacities, the heat exchange surfaces for forced

convection, conduction and free convection with ambient are selected.

The 3D CAD model includes the engine cylinder block material and the

fluid domain corresponding to the water jacket.

LMS Amesim




At the sketch generation, the thermal connections are

automatically performed.

The type of heat exchanges (forced convection, free

convection, and conduction) are selected accordingly.

Application: aircraft environmental control system (ECS)

The main purpose of the pneumatic distribution system is to supply

high-pressure air from the sources to the consumers.

A pneumatic distribution system connecting the engine bleed systems,

the APU and the air conditioning consumers is considered here.

We start from the following CAD model of an aircraft pneumatic distribution

system created with Siemens NX software.

This CAD model is imported in the

CAD2AME productivity tool of LMS Amesim.

NX




The next step is the primitive association.

LMS Amesim




The final step is the LMS Amesim model generation.

Since all parameters are set automatically, the model can be run to get the

distributions of mass flow rates and pressures in the system.

Application: pneumatic piping network of a power plant

The cutting plane can be enlarged so to be able to cut the body into

several parts at once. In complex piping network, some

bodies have to be split in

elementary elements.

With the Split body feature the 3D

CAD model is pre-processed to

prepare it for the primitives

association.

sketch can be generated in LMS Amesim with parameters settings

Customization



LMS Imagine.Lab Amesim supports Modelica, the open standard language for

describing physical systems. The Modelica platform provides the tools you need to

build acausal, multidomain Modelica models and leverage the LMS Amesim platform

features to analyze the resulting system.

LMS Amesim can be coupled with external software applications such as CAE, CAD,

CAM, FEA/FEM and computational fluid dynamics (CFD). Co-simulation provides

coupling between LMS Amesim and CAE tools with predefined setups to ensure good

dialog between the tools and simulation software.

LMS Amesim provides co-simulation capabilities with any software coupled with LMS

Amesim due to the generic co-simulation capability and functional mock-up interface

(FMI), to complete heterogeneous simulations within an unique integration platform.

The LMS Amesim unique integrated platform provides realistic plant models for every

stage of the development cycle, enabling system and control engineers to start

evaluation and validation phases early in the design cycle using model-in-the-loop

(MiL), software-in-the-loop (SiL) and hardware-in-the-loop (HiL) frameworks.

LMS Amesim integrates cutting-edge numerical methods, performance analyzer,

discrete partitioning library for CPU speed-up, a parallel processing feature for

multiprocessor task distribution as well as High Performance Computing (HPC).
