InsightCAE – The Idea
To use open-source software productively and efficiently for daily tasks, the automation framework InsightCAE by silentdynamics is provided. InsightCAE serves as a framework for the automated execution of analysis procedures. The goal is to provide interfaces to all tools and simulation programs required for a specific calculation task. Our additional service: individual open-source projects.

Ocean behavior
The analysis of wave load calculation is typically performed using potential flow codes. It involves the calculation of Response Amplitude Operators (RAOs) for all degrees of freedom. From these RAOs, accelerations, velocities, motions, and other parameters are computed at various locations. The simulations are carried out using the open-source tools PDstrip or NEMOH. The required input is compatible with

High Speed Planing Craft
The simulation of high-speed planing ships is a challenge with VOF methods. This is because several numerical problems occur at high speeds. We have implemented solutions for this and are able to deliver reliable results in a short time at low cost.

Ship resistance
With our InsightCAE Framework, we offer fully automated ship resistance calculations using exclusively open-source CFD software. This not only eliminates software license costs, but also enables users with little specialized knowledge to perform the rather complicated CFD analyses thanks to the automation.
Turbomachinery and Propellers
-
Propeller design
We perform basic performance analysis and design of turbomachinery using state-of-the-art CFD methods. The entire analysis workflow is fully automated in the InsightCAE framework and uses only open source software. This enables very cost-effective simulations, short turnaround times and easy integration into automated optimization frameworks.

Fiber composite propeller blade
Propellers with blades made of fiber composite materials (e.g., CFRP or GFRP) are flexible. During design, the deformation of the blades under operating load must be taken into account. We have developed a software solution to perform the necessary CFD simulations with fluid-structure coupling using OpenFOAM and Code_Aster.

Cavitation
Cavitation is a limiting phenomenon for turbomachinery operating in fluids. CFD simulation is the most reliable method for predicting the onset of cavitation and its effects on machine performance.

Propulsion Analysis
After determining a propeller open water curve using CFD or another calculation method, further analysis, e.g. propulsion analysis, is required to predict the propulsion performance for a specific vessel. We have developed analysis software solutions for seamless integration into the design process, relying exclusively on open source software.

Coupled Heat Transfer – Conjugate Heat Transfer
In some simulation problems, not only heat transfer within the fluid itself is important, but also heat transfer in the adjacent solid. In such cases, a coupled simulation of heat propagation between the solid and the fluid (CHT – Conjugate Heat Transfer) must be performed. We are proficient in such simulations using our open-source tools, such as OpenFOAM. For rapid optimization of heating and cooling performance via

Dispersion of gases in the environment
Gases escaping in the event of an incident (light, heavy) are assessed using CFD, taking into account the nearby and distant environment. Stationary and transient concentration fields show the critical dispersion and its influence at different wind directions. The use of specially developed transient inflow boundary conditions in atmospheric boundary layers enables high reliability of the simulation results.

Cooling of electronic components
With 3D simulations, a thermal analysis is performed for cooling various components (electronics, light sources). By quantifying heat radiation and heat conduction, as well as free and forced convection in different cooling concepts, functionality is ensured even during the development process.
