Simulation solutions for systems engineering and virtual testing

Everything we do at Claytex is about modelling and simulation

Systems Engineering is a broad topic and here at Claytex we focus on the modelling and simulation of the system to understand its behaviour and dynamics. Our work covers multiple industries and domains such as vehicle dynamics, energy management of buildings, flight dynamics of drones, thermal management and extends into the virtual testing of ADAS and autonomous vehicles with physics based sensor models. We help our customers understand their designs to make better products, faster.

Claytex is a consultancy, software developer, distributor and training provider. We develop simulation solutions using the open standards of Modelica, FMI, OpenSCENARIO and OpenDRIVE; distribute systems engineering solutions from Dassault Systemes, rFpro and specialist Modelica library developers. Our portfolio of tools includes Dymola, Reqtify, rFpro as well as our own software products including the VeSyMA suite of solutions. We also build bespoke simulation tools for specialist applications.

Dymola is a modelling and simulation too that uses the Modelica modelling language. It provides a component orientated, physical modelling approach that covers multiple domains allowing the system interactions to be studied and supports extensive reuse of models and modelling knowledge.

rFpro enables sensor realistic simulation for the virtual testing and development of ADAS and autonomous vehicle control systems. It allows the controllers and the driver (or occupants) to be immersed into the virtual environment. Injecting traffic, pedestrians, cyclists and other dynamic agents into the virtual world enables complex test scenarios to be simulated.

Consulting

Our engineers work on a diverse range of projects and are experts in their respective fields. We can help by analysing your designs to quantify their performance, provide detailed support to help you improve your own models or developing a solution to help your team make better use of simulation.

Our Multirun tool is built on our in-house regression test solution for Dymola and Modelica models. It enables the parallel simulation of multiple Dymola models on one PC so that the impact of changes in a model can be quickly assessed across the full suite of experiments you use to assess the system behaviour.

Claytex develops and distributes a wide range of Modelica model libraries. These application libraries are designed to work with Dymola and cover a broad range of engineering tasks and industries including hydraulics, hvac, multibody mechanics, cooling, powertrain, vehicle and flight dynamics.

New Layer

The FMI Standard is an open standard for exchanging models between different simulation tools. Claytex fully supports this standard and has developed FMI compliant tools for Simulink, Excel, Windows and the Cloud. Our VeSyMA suite of products also fully support the FMI standard in both Dymola and rFpro.

Training

We offer a range of instructor led training courses covering all of the software tools we distribute including Dymola, Modelica, and rFpro. All our training courses are now delivered online and can be tailored to suit your needs. With all our courses you will still interact with an instructor via a web meeting.

Reqtify captures requirements from any source and performs traceability and impact analysis across different systems, programs and project levels covering the complete product life cycle. It connects to your existing tool chain and automates the extracting of information enabling an accurate, live view of the project status.

AV elevate, the new solution from rFPro for sensor-realistic simulation, integrates simulation and physics-realistic sensors into your processes for developing and validating AV driving functions. Built from the ground up using the class leading simulation solution rFpro, AV elevate is an autonomous vehicle simulation solution designed to test, develop and validate AV safety.
