Research and Development

In addition to participating in pioneering development projects and providing a wide range of simulation services to various industry players, our department takes part in smaller-scale research and development projects. With our equipment, we can be cost-effective partners in any period of development process.

Future R&D projects

C3D Ltd. maintains close cooperation with the Budapest University of Technology and Economics, the Faculty of Technology and Informatics of the János Neumann University and the Energy Science Research Center. As a result of these collaborations, our company has been involved in pioneering international research projects such as the International Fusion Reactor (ITER) or the design of the cooling system and other systems for the fusion neutron source (IFMIF-DONES) for more than five years. Highlighting some of our joint developments with our engineering department it would include project such as, the design of an active medical rehabilitation device, a wave pool, as well as the design and prototype production of a hydromechanical press machine operating on new principles.

Our references in the ITER project

Our company has a long standing history of development diagnostic cabling running in the vacuum tank of a reactor, which connects the components of the fusion process control instrumentation system. During the project, we facilitated the development of each component from the conceptual phase to the production support with our extensive mechanical engineering knowledge.

In addition to diagnostic cabling, we are involved in the design of thermal shields in “Port Plugs” to protect diagnostic shelves. We design the cooling piping layout of the plasma shields, which are checked according to the RCC-MRx standard.

Our references in the IFMIF-DONES project

C3D Ltd. Participates in the IFMIF-DONES neutron source design project as a significant industrial contributor.

We helped to implement the following subtasks:

  • design of secondary and tertiary heat extraction system (sizing of heat exchangers, arrangement of pipelines, design of support structure, thermohydraulic and thermomechanical analysis)
  • design of main test module (HFTM) mounting
  • simulation of the propagation of contaminants in the lithium circuit
  • thermohydraulic simulation of a test cell cavity

 

Simulations and analyzes

One of the modern tools for verifying designed structures is virtual testing. In doing so, the structure can be validated using computer simulations to prepare or even exclude physical tests. Our company maintains official approval in the feild of structure analysis (FEA), rigid body dynamics (MBS) and flow dynamics (CFD).

Our experience of many years of using numerous specialized software helps us to understand our customers’ problems and solve them up to the highest standards. By evaluating the results of the simulations, we support the decision of our partners in all phases of their product development cycle.

Fluid dynamic simulations (CFD)

  • Simulation of incompressible fluids in steady state and transient state
  • Single and multiphase flows
  • Thermal transport in liquids and solids (CHT)
  • Natural flows and radiation

Software competencies:
OpenFOAM, Fluent, CFX, Code_Saturne

Mechanical and thermal simulations

  • Structural simulations (various types of assemblies)
  • Linear and non-linear problems (material non-linearity, contact problems, handling of large deformations)
  • Dynamic simulations (harmonic analysis, response spectrum analysis, random excitation simulation, modal-based and direct transient studies, handling of non-linear cases: implicit, explicit)
  • Fatigue tests (for welded structures)
  • Constant and transient, linear and non-linear heat transfer and coupled thermo-mechanical simulations.

Software competencies:
Ansys (Workbench and APDL), NX.Nastran, Abaqus (Standard and Explicit), Code_Aster, EDF.Syrthes, Bentley STAAD.Pro, Creo Simulate

Simulation of coupled physical systems in Modelica

  • 1D Thermal and flow simulations
  • Rigid-Body dynamics
  • Multiphysics

Modelica is a special programming language that is similar to e.g. Matlab-Simulink, suitable for simulating dynamic systems. Due to its structure, different physical domains (mechanical, electrical, thermal, flow, regulation / control) can be easily connected, so that the temporal behavior of very complex systems can be studied. Our colleagues are adept at the implementation of the open-source OpenModelica, which is backed by many universities and large industry players (eg Bosch, ABB).

Personalized workflows, simulations

In a development process, it may be necessary to combine several simulation solutions, software components, perform a large amount of parametric testing or even optimization. Our department, mainly relying on open source (eg OpenFOAM, Code_Aster) simulation tools and several years of programming experience, also undertakes the compilation of special workflows / simulations suitable for the given development task in a cost efficient manner.
