Discover the new SimulationX – Highlights in this release:
New: Simulation of Switched Controls for NVH Analyses
- Electro-Mechanics model library: Simulate and analyze torque ripple as a source of noise or vibration excitation caused by discrete controllers for electric drivetrains. All field-oriented controller models and the corresponding controlled inverter models, the rectifier model, the inverter model and the frequency converter can now represent discrete circuits.
- With the new model of a switched inverter for three phases you are now able to perform detailed analyses of switching effects in inverters to assess losses as well as current peaks, but also to examine control systems. Furthermore, the new inverter leg model (one phase) lets you create custom inverters easily and quickly.
System Reliability and Safety Analyses plus Fault Data Analytics
- New Fault Data Analytics tool: Create decision trees and main metrics based on the simulated data from your studies to evaluate system reliability and safety for certain scenarios. For this purpose, SimulationX now comes with the new Fault Data Analytics tool (FDA) which is based on scikit-learn package for Python and offers seven algorithms for machine learning with an intuitive user interface. This new analysis tool lets you find out how manufacturing deviations, assembly faults, material deviations, wear and aging can contribute to progressive or sudden failure of your system or which combination or limits must be prevented or not exceeded in real operation.
- New generic fault model augmentation
- Extended variant study generation
Simulations as accurate as necessary and as simple as possible
Users of SimulationX value its capability to simulate even the most complex mechatronic systems with only little effort and to run numerous variation calculations fast and conveniently. As a Modelica-based tool, the simulation software leaves it up to you whether you prefer using pre-configured elements from the SimulationX model libraries or whether you want to create your own model elements for custom-built libraries. Based on models with undirected connections, you can optimize a system’s dynamic behavior precisely – also for great nonlinearities. Our experienced engineers are there to support you in all areas of modeling, simulation, result quality and interpretation for your design implementation – be it through personal contact as part of your maintenance agreement or in one of the many trainings we offer at the Agito Academy.

The majority of complex subsea Power & Communication (P & C) systems will in their lifetime experience problems executing commands or giving feedback from subsea transducers. This can be software problems or malfunction in components. Some of the components will also see some degradation over time, which again can influence in system behaviour and require an operation outside the system limits set during commissioning.

This article describes how modern simulation tools such as SimulationX® can be applied to help realize the challenges of using accumulators in deep water BOP & IWOCS control systems.
Modeling and simulation tools have developed into various software applications for different domains. Some tools specialize in finite element analysis, some in computational fluid dynamics, some in hydro-dynamics, others in hydraulic system response analysis, and so forth. Currently, there is no software provider which includes all physical domains in one single CAE tool. The CAE tool potentially compromises the simulation performance due to the difference in numerical stiffness required for each physical domain, where pure rigid multibody dynamics can be solved quite fast, but the nature of fluid power systems introduces much higher stiffness.
In particular, offshore systems, like a riser tensioner or an offshore crane for subsea installation, pose many challenges for the CAE engineers due to the many different physical domains; hydro-dynamics, structural dynamics, multibody dynamics, fluid power, electrical actuation and more.
In order to overcome these challenges, Agito have developed a set of sample files on how the widely used ‘OrcaFlex for hydrodynamics and mooring systems can be co-simulated with the multi-domain software package SimulationX®, which is widely used for dynamic analysis of the surface and subsea equipment.
Utilizing co-simulation, the engineers obtain a fully analytical simulation where all coupled effects are handled. This gives more accurate and realistic simulation results, as well as saving the engineer’s time determining how to obtain the relative input for each of the domains. In the offshore industry, many companies have engineers working with hydrodynamic analysis on one side of the table struggling to estimate the applied forces from cranes, riser tensioner systems, etc. and on the other side of the table engineers using detailed models to establish motion input for vessels in order to evaluate the performance of their hydro-mechanical systems. Co-simulation will save engineering hours and increase the accuracy of the analysis.

“We have always done it that way”.
This can be seven expensive words if used in an industry that continuously search for safety improvement and cost reduction.
Data Respons and Agito have performed a study where the scope is to explain how Hardware-In-the-Loop can be applied in the development of, and test of subsea control system software. The study points on what improvements can be expected on both safety and development cost and is partly funded by Innovation Norway and NCE Systems Engineering Kongsberg.
The oil and gas industry has always improved their technology and pushed the limits for what’s possible in harsh environments. New technology has continuously been applied, limits has been challenged and needs for new and enhanced test methods have been a result of this. Installation and Work-Over Control System (IWOCS) is a system which has local control of the well whilst operating on a live well. Risk for accidents with impact on equipment, personnel and environment is high. At the same time it is a constant demand from the operators that the well maintenance shall be performed as fast as possible and failures, which can result in extra hours of lost production, is not an option.
By introducing Hardware-in-the-Loop (HiL) as a test method on IWOCS, the risk for control system failures are reduced. System upgrades and reconfigurations to different subsea systems and environments, can be thoroughly tested onshore before sent offshore for installation. The required time for testing offshore can be reduced without reducing the level of safety in the process.
System level testing is one of the major expenses in developing Embedded Control Systems for offshore installations. The need to minimize time to market while simultaneously producing thoroughly tested products present tremendous challenges. Increasing levels of complexity in system hardware and software are making this problem more severe with each new generation of products. Additionally, any significant changes to an existing product’s hardware or software must be thoroughly regression-tested to confirm that the changes do not produce unintended effects.
Using HiL simulation technology for testing control systems makes it possible to perform extensive testing at early stages of the development process. Safety routines can be developed, optimized and verified against systems with same response as the real systems without damaging equipment or creating hazard situations for test personnel.
