Digital simulation
Calculation methods
to serve your needs
From the development of your test strategy to the final qualification phase, you have Sopemea's expertise in test engineering applied to digital simulations, allowing you to anticipate and verify the performance of your equipment. or system, exposed to constraints in mechanical, climatic or electromagnetic environments.
Customised
Services
Would you like to entrust us with a study by mechanical, climatic or combined simulation? We can perform the following services on your equipment:
- Verification and validation of the mechanical strength of equipment and interfaces subjected to a static, vibratory, seismic environment
- Prediction of the lifespan of a material according to the Eurocodes
- Identification by modal correlation
- Numerical validation of test interfaces
- Modal correlation between the analytical and measured modes (calculation of MAC)
- Digital model registration between analytical and measured modes (Moore Penrose Method, Bayesian Method)
- Digital validation of test tools
- Calculation of the transferred spectra (synthesis of a temporal accelerogram, transient calculation in modal superposition, calculation of the response spectrum)
- Quasi-static accelerations on antenna
- Linear and nonlinear mechanics
- Fatigue and endurance calculations
- Static and dynamic mechanics (vibrations / shocks)
- Frequency and / or time calculations
Tools for calculation:
- FEM software: ANSYS Mechanical APDL / WORKBENCH software
- Correlation and recalibration software for calculations / tests: FEMTools (DDS)
- Matlab
Multiple
Analysis
Are you looking for a service provider for an electromagnetic simulation study? We suggest that you perform several analyses on your equipment and systems:
Electromagnetic analysis - lightning, Strong Fields, IEMN and CEM
- Optimization of test set-ups
- Determination of field, current and voltage stresses
- Parametric analysis of protections on structures and cabling
- Electromagnetic analysis - positioning of antennas on carrier
- Carrier modeling
- Study of each isolated antenna and on carrier
- Radiation patterns, Gain, S11
- DRAM / DREP study
Comparison of simulations / measurements
- Gap analysis
- Proposal for a calculation methodology (worst case or parametric approach)
- Extraction of standardised data with control of margins
Simulations of environmental nuisances (rail, naval, etc.)
- Radiation mapping
Types of calculations for electromagnetic simulations
- Time codes → processing of the entire frequency band in a single calculation
- Lightning / HIRF / IEMN frequency exploration: [10Hz - 1GHz]
- Antenna radiation (up to 10 GHz)
- Carrying out post-processing adapted to the analyzes (signal processing, standardised waveforms, etc.)
- Development of a digital model for a specific need
Tools: calculation codes
- CST MWS + GPU Accelerator (Dassault Systems): 3D time and frequency solvers, Cables Studio, Design Studio (1D)
- GORF3D (CEA Gramat): Maxwell 3D time solver
- Calculation machine with GPU card
