Accelerating Finite Element Analysis in MATLAB with Parallel Computing

The Finite Element Method is a potent numerical technique for figuring out partial  and ordinary differential equations in a array of composite engineering and science applications, such as structural engineering and multi-domain analysis . It calls for breaking down the investigation domain into a distinct mesh before fabricating and then figuring out a system of equations built over mesh components. The number of equations called for grows as the mesh is complicated, building the Finite Element Method computationally very intensifier. By contrast, respective degrees of the procedure can be well parallelized.

Developer execute coupled electro-mechanical finite constituent analysis of an electrostatically actuated micro-electro-mechanical (MEMS) device. Developer can  enforce parallel computing techniques to the most computationally intensifier part of the mechanical analysis stage. Applying a 40-worker1 setup, developer will cut down the time taken for the mechanical analysis with an more or less one-million DOF mesh from almost 60 hours to less than 2 hours.

MEMS Devices

MEMS devices by and large comprise of thin,  movable beams, , high-aspect ratio, or electrodes suspended over a fixed electrode . They incorporate mechanical constituents on silicon substrates employing  microfabrication.

The electrode distortion caused by the application of voltage among the fixed and movable electrodes can be employed for switching, actuation  and other signal  data processing purposes.

FEM renders a commodious tool for qualifying the inner working of MEMS devices so as to anticipate stresses, temperatures,  possible failure mechanisms and dynamic response prominent attribute. One of the most common MEMS alternates is the cantilever series. This dwells of beams set aside over a ground electrode.

When a voltage is enforced among the top electrode and the ground plane, electrostatic charges are brought on on the surface of the conductors, which chip in rise to electrostatic forces behaving normal to the surface of the conductors. As the ground plane is determined, the electrostatic forces change shape only the top electrode. When the beam change shape, the charge redistributes on the surface of the conductors. The resultant electrostatic drives and the distortion of the beam in addition, change. This procedure goes forward till a state of counterbalance is reached.

Mechanical Analysis

The mechanical analysis calls for five steps:

Interlocking the domain

Deducing constituent-level equations


Enforcing boundary considerations

Figuring out the equations
