A residual flux density of 1.2T was used for the simulation.
For the micro pump in our study, we plan in the future to investigate the velocity dependency further by measuring the membrane displacement as well as using CFD (Computational fluid dynamics).

Given the complexity and curvature of the CAD model, tetrahedral meshing was opted to enhance accuracy and reduce computational time [10].
2.3 Finite Element Analysis
After importing the developed CAD file into the Ansys Modeler Workspace in IGES format, the crucial meshing process was undertaken to facilitate precise simulations through finite element analysis (FEA).
2.3.1 Loading conditions
In practice, human teeth exhibit a complex and inhomogeneous structure, comprising layers like enamel, dentin, and the dentin-enamel junction.

Abstract.
Numerical simulations have contributed considerably to the knowledge about the Honji instability (see e.g.
All simulations of regime A are related to Re = 100 and KC = 5.
Simulations were carried out for a very long time, corresponding to about 200 cycles.

Figure 2: Flowchart of performed simulations.
Numerical Modeling For the numerical simulations, all geometries and meshes were constructed with the open source program Gmsh 2.16.0, in which the domain is discretized in finite rectangular volumes.
The commercial CFD package FLUENT® [10 - 11] based on Finite Volume Method is used to solve Eqs. (1) – (4) for different fin configurations (H1/L1 and H2/L2) and fluid properties shown in Table 1.

Due to the complexity of experimental
determination of the heat fluxes and the cooling rates during and after a welding, the numerical
simulation has become an interesting tool for the prediction of the temperature field and the flow
conditions in the molten pool.
An exception is represented by the work of Tanaka et al. [6], in which both the arc and the anode domain are included in the simulation.
Figure 1: Standard TIG welding configuration In the Table 1 we summarize the process parameters and the material properties adopted in the present simulation.
Summary In the present study we employ a CFD commercial software for predicting the results of a stationary TIG welding process, in particular we are interested the molten pool shape, which determines the weld bead geometry and performance.
