Small satellites - Digital twin

The nanosatellite and microsatellite market is projected to grow from an estimated USD 1.21 Billion in 2017 to USD 3.49 Billion by 2022, at a Compound Annual Growth Rate (CAGR) of 23.7% during the forecast period, from 2017 to 2022 according to Market and Market in its study “Nanosatellite and Microsatellite Market by Component (Hardware, Software & Data Processing, Services, Launch Services), Mass (1 kg-10 kg and 11 kg-100 kg), Application (Earth Observation & Remote Sensing), Vertical – Global Forecast to 2022“.
The growing number of missions covered with microsatellites increases the needs for numerical simulations.

Create a 3D model suitable for FEA

Fom IGS to 3D solid

Very often, the provided CAD model is not adapted to CAE because it is made of a collection of surface (and not 3D solids) and contains details that are not relevant for the type of insights one wants to gain from the numerical mock-up. Our simulation workflows makes it easy removing unnecessary details and constructing 3D solids.

A typical FEM model used for simulations

Multiphysics simulations

Structural design

During the launching, a satellite is submitted to static and dynamic loading. Using the OOFELIE::Multiphysics solver permits to consider: modal analysis, and random vibration (PSD) analysis.
The picture on the rigth shows one mode of vibration for e.g.

Thermal design

The OOFELIE::Multiphysics solver permits also to assess the impact of thermal loads during operation in Earth orbit.
The picture on the left shows the temperature distribution a a given time for e.g.

Analyse the behaviour of your satellite with its payload and equipments

In the following video, the variation of the temperature distribution inside a Cubesat is presented. Temperature changes with respect to its position in orbit. Deep space, earth albedo and heat generated by electrical equipment’s inside the microsatellite are taken into account.
