Analytical Solutions implementing CAE Techniques

Multiphysics analysis for stractural, thermal and fluid flow phenomena and Validation of design based on various standards and codes

 We offer a variety of CAE (CAD, CAM etc.) engineering services based on the abundant experiences accumulated through the long-year engineering services in the field of nuclear power business. We propose customers the best appropriate approach to their problems from various aspects based on our expertise encompassing various CAE and manufacturing techniques.

■Services for numerical analysis by CAE

 We provide a wide range of CAE analysis relating to energy, civil engineering, architecture, machinery, automobile, aero-space, EDA, consumer related services, etc. The analysis cover extensively multiphysics fields such as large scale thermo-structural analysis, thermo-fluid analysis, fluid analysis, integrated fluid-stractural analysis, etc. In case of developmental project, its design must be assessed and validated by appropriate design criteria or standards. We are able to provide assessment report of the design with reference to the relevant design criteria or codes such as JSME, ASME, etc.
 < Software implemented for CAE analysis >
 ・Pre-/Post-proccessor:Femap, HyperMesh
 ・Analytical tools:ANSYS, NX Nastran, ABAQUS, ADINA, LS-DYNA, FLOW-3D

■Consulting services on CAE

 We provide on-site consulting services by dispatching CAE experts to the customers who need support in practicing CAE.
