Abstract Self-optimizing process planning is an essential approach for finding optimum parameters and reducing ramp-up times in machining processes. For this purpose, polishing presented as application example. In conventional processes, the are selected according to operator’s expertise order achieve a high-quality surface final production step. By implementing machine learning (ML) models pla...

We present the latest results of our research regarding meshes suitable for both process and device simulation. Two major results are discussed in this paper: a consistent multi-dimensional mesh quality definition and a new hybrid multi-dimensional mesh generation approach. The consistent definition achieved is based on the conditions imposed by the Box integration method applied for both semic...

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

modelling and forecasting stock market is a challenging task for economists and engineers since it has a dynamic structure and nonlinear characteristic. this nonlinearity affects the efficiency of the price characteristics. using an artificial neural network (ann) is a proper way to model this nonlinearity and it has been used successfully in one-step-ahead and multi-step-ahead prediction of di...

Fluidity is open-source, multi-scale, general purpose CFD model. It is a finite element model using an unstructured mesh which is adapted during the course of a simulation. Reordering of the mesh elements and vertices has been implemented, reordering occurring at input and at each adapt step. For an OpenMP simulation using all 4 UMA regions in a single HECToR node, a 3‒5% performance improvemen...

plant tissue culture is an alternative method of commercial propagation and is being used widely for the commercial propagation of a large number of plant species, including many medicinal plants. somatic embryogenesis is a process by which asexual or somatic cells are induced to form embryos in culture. somatic embryogenesis is a multi-step regeneration process starting with formation of pro-e...

It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...
