Ship EDF is a software framework conceived for the electromagnetic design of naval vessels. It is a comprehensive system capable of supporting concurrent electromagnetic design and assisting the optimization of naval platforms. It is a modular system which can provide coverage for EMC/EMI assessment including antenna placement and radiation hazard identification, as well as radar cross section (RCS) and infrared (IR) signature analysis.

Ship EDF-IR Module:

Ship EDF-IR provides a single environment for all the different tasks required to perform IR analysis. It provides an easy and intuitive graphical interface and an efficient and stable management of all the data required during the design phases. It has been developed to supply a global ship signature environment supporting the ship project from the survivability point of view and is combined with the Ship EDF–RCS module. It is focused on aspects such as thermal distribution, IR emission diagrams, plume analysis.

The use of standardized commercial components shared between several projects, together with customized solutions, is a typical practice on ship design projects.

Ship EDF includes an embedded comprehensive library management system to match the needs of the designers throughout a project’s different stages.

The library of environments, materials, exhaust gases, compartments, sensors and partitions is fully customizable through the provided interface.

Environment Database InterfaceThe user can choose the Atmosphere Models present in the interface: air temperature is automatically populated with the standard value for that model. The user can choose the Aerosol Models present: Air mass characteristics and 24 hr. averaged wind speed are defined as a function of this value. There are standard values of visibility for each value of Aerosol Model. The user can choose the Cloud Models present. The Rain Rate (mm/hr.) field is enabled for some cloud model values and in these cases the user can insert a value for the Rain Rate (mm/hr.). The user can insert a value for the humidity or can take the default humidity value for the selected atmosphere model.


Materials Database InterfaceEach material is characterized by its Conductivity expressed in Watt/m °K, Sun Absorptivity, Thermal Emissivity and IR Emissivity. A flag enables the use of conductivity on thermal computation (for instance, paints are not used in thermal conductivity computations but are considered in the IR emission with their proper emissivity). There is also a flag that enables the use of BRDF (Bidirectional Reflectance Distribution Function) and the introduction of the Specular Component Lobe (deg). The user can import the IR emissivity and BRDF values from an ASCII file.




Exhaust Gases Database InterfaceThe exhaust gas tool allows the creation of an exhaust gas database. Each exhaust gas is characterized by temperature, mass flow and gas composition:

  • H2O
  • CO2
  • CO
  • N2
  • O2

Sensor Library InterfaceThe sensor library is used to collect all the information related to the IR camera models which will be used to perform the analysis within the project. The sensors are characterized by their fields of view, focal length, detectivity, band and frequency response, values for which can be inserted independently for each frequency.



When dealing with complex designs, such as military warships which are a balanced compromise between several structural aspects and combat system performances obtained through several iterations, the importance of correctly managing the project data assumes a level of significance comparable with the validity of the mathematics behind the numerical simulations.

In the Ship EDF framework, a Ship Project is the top level entity which collects all the data related to a particular ship (the concept is also extended to components in the case of RCS signatures).

The data related with a project can be classified into the following categories:

  • Ship CAD models;
  • Equipment and component configurations;
  • Electromagnetic mesh models (whole ship or subparts);
  • Analyses, including all the related post-processed results.

The Ship EDF framework implements a versioning mechanism on projects that allows the user to keep a record of iterations of the design evolution of the equipment configuration.

In general, Ship EDF considers a design version valid when it is characterized by:

  • 3D CAD drawings of the Ship;
  • Equipment configuration.

The configuration of the equipment on the ship, together with the CAD drawings, constitutes the essential information for the project setup.

CAD drawings can be imported from several formats (such as Microstation (DGN), AutoCAD (DWG), CATIA (CADPART), IGES etc.) and can be edited and managed in Ship EDF thanks to the integration between Ship EDF and Bentley Microstation.

In Ship EDF-IR the Equipment Configuration interface is part of the CAD drawing section when the IR module is installed stand alone, otherwise it is managed through the EME or RCS section.

The “Combat System Equipment List” is setup within a specific section of Ship EDF (accessible only from the main toolbar in the EME and RCS environments) which opens an interface allowing equipment to be picked up from the database and placed on the CAD model of the ship.

Ship EDF AEM MesherA meshing tool is embedded within the Ship EDF framework which provides a comprehensive environment dedicated to the preparation of numerical models (mesh) suitable for the electromagnetic solvers.

The AEM Mesher tool (completely developed by IDS) provides an intuitive GUI based on OpenGL ® graphics libraries and is able to import geometries from Bentley Microstation (through dedicated control interfaces working inside the CAD) or directly by reading external CAD files such as CATIA, NATRAN, IGES etc.

The interface is unique and independent of the working band or type of mesh under construction (EMC, RCS, IR) and is automatically configured by the framework to propose to the user the functions and options required for the current mesh type.


The IR module provides:

  • Fully customizable IR material parameters and scenario definition databases.
  • 3D geometrical modeling tools for the external structure.
  • Modeling of internal compartment heat sources and exhaust ducts.
  • Parameter set up for scenario environments.
  • Temperature distribution, IR imaging and signature.


Integrated in the Ship EDF software framework conceived for ship electromagnetic design, this IDS IR Prediction solution has been developed to supply a global ship signature environment supporting the ship project from the survivability point of view and is combined with the Ship EDF–RCS module. It is focused on aspects such as:

  • Thermal distribution;
  • IR emission diagrams;
  • Plume analysis.
