Through the use of COMSOL software, Unictron has built simulation capability for piezoelectric elements and piezoelectric modules in recent years.  The simulation technology uses mainly the principle of finite element method (FEM) to perform analysis and simulation.  Finite Element Method (FEM) is a systematic method used for numerically solving differential equations or integral equations, thus it can solve for a variety of complex geometric shapes or different boundary conditions.  By dividing a large system into smaller, simpler parts, i.e. finite elements, generating mesh, followed by optimization\/post-processing, simulation, modularization and other related functions, it can be used effectively to explain multiple coupling or multiple physical phenomena.  Multi-physics coupling analysis can be used to simulate optics, structure, fluid, heat, chemistry, acoustics, etc. with applications in the fields of engineering, building, aerospace, semiconductor, medicine\u2026 etc.<\/p>\n\n\n\n

In the simulation process, the first step is to perform 2D\/3D modeling and to define the parameters in integral formula; the second step is to set material parameters of each part, such as density, Young`s modulus, Poisson`s ratio, thermal conductivity, etc.  The meshing step is followed afterwards.  By meshing, it means to divide the model structure into many small units. Tetrahedral meshes are typically used for segmentation in 3D models.  When the model is divided into many small meshes, there are various mesh points at the end points which are also called nodes.  The finite Element Method (FEM) is used to calculate the value at each node.  The final step is to set the required expressions that need to be solved, such as frequency domain, steady state, time dependence, linear buckling, etc., to complete the simulation process<\/p>\n\n\n\n

Through the above simulation process, data such as the resonant frequency, resonant mode, stress analysis, amplitude analysis\u2026etc. for the piezoelectric element or piezoelectric module can be obtained.  Based on the results of the analysis, optimization adjustments can be further proceeded, such as: modification of geometric shapes, materials, mechanisms, etc.<\/p>\n\n\n\n
