Design Simulation: 3D CFD Simulation
We analyze the fluid-dynamic
performance of a product in terms of
flow-rate, pressure losses, particle
transportation, mixing efficiency, or
temperature distribution and quickly
provide useful insights to move
forward with your design optimization
proposals.
Design Simulation: Multi-objective Parametric Optimizations
Advanced optimization algorithms allow us to explore
new design alternatives, sweeping across a defined
design space, to select a combination of design
parameters that allow your product to reach target
performance levels, while respecting production and
cost constraints.
We use multi-objective optimization software to detect
the best combination of design parameters necessary to
reach desired performance levels, whilst ensuring the
respect of imposed or required constraints.
Design Simulation: Finite Element Method (FEM)
We carry out FEM calculations to evaluate the structural
performance of a product and perform complex
analyses on advanced materials like Carbon Fibre
Reinforced Plastics (CFRP), Metal Matrix Composites
(MMC), post-buckling phenomena, bonding failure, durability, damage progression, and more...
A structural analysis allows simulating the behavior of
complex physical systems by means of specific calculation
codes (pre- and post-processing, thermal analyses,
optimizations).
Design Simulation: Boundary Element Method (BEM)
In engineering, numerical modeling and simulation are widely used for solving complex problems.
The BEM approach is very interesting in this way, as it allows to solve numerous problems, especially those, that require the use of differential equations.
The method is based on the discretization of the domain of the solution only at the boundaries, reducing the size of the problem and thus simplifying the required input data.
It is based on the resolution of an integral equation defined on the boundary instead of on the direct resolution of partial differential equations as is the case of FEM. In BEM, the starting equation is reformulated with an integral equation defined on the boundary of the domain (BIE - Boundary Integral Equation), and an integral that correlates the solution on the boundary with the solution in the internal points.
BEM can be widely applied to electromagnetic problems associated with electrical machines; to problems of airborne acoustic emission, fracture mechanics, potential flow around the airfoil and all those problems in which it is possible to define an integral equation.
Design Simulation: FEM / BEM – Differences and Advantages
Advantages of BEM:
The main advantages of this method can be identified with the simplicity of building a 3D model having to discretize only the surface of the body, the high precision for calculations in which the results on the border have a preponderant importance compared to those inside and with the adaptability to problems with open or mobile boundaries.
Advantages of FEM:
Typical advantages of FEM are found in the simplicity of solving non-linear problems and in the versatility of being extended to transient problems.
Advantages of both, BEM and FEM:
It’s beneficial to verify results by comparing the 2 different methods.
