CEDRAT: Ship magnetisation

Ship magnetisation

Pioneering the computation of electromagnetic fields related to ships, Flux has become a known and leading reference in the domain of ship magnetization simulations. It is one of the only software solution to provide a solver able to model both silencing systems and corrosion protection systems.

- Design and optimize degaussing coils and silencing strategy

- Design and optimize ICCP systems - Impressed Current Cathodic protection anodes

- Simulate the influence of ICCP anodes on the ship signature…

Grandeurs de sortie

- Ship induced magnetization, magnetic field and flux density inside and outside the ship, magnetic anomaly, Eddy currents in the ship hull…

- Underwater Electric Potential Field (UEP), Corrosion Related Magnetic Field (CRM), conduction currents in the water and the ship hull…

Avantages

- Thin surface regions: unique computation mode to avoid volume mesh in the hull and optimize calculation time

- Reduced potential formulation: For a better accuracy on the magnetic anomaly

- Advanced CAD import and healing capabilities: from neutral formats (STEP, IGES, DXF,...) to native formats ( SAT, INVENTOR , Pro_E, Catia V4, Catia V5...)

- Infinite box: for open boundaries and far fields computation while keeping a light study domain

- Easy definition of coils and earth source field
