in this study, the recovery of casing soil consumed in the white button mushroom was investigated. casing soil is used as a layer on compost (culture medium) to a diameter of 3-5to stimulate fruiting on the white button mushroom(agaricus bisporus) . the expense od casing soil is about 30 percent of production costs. in the first step of this experiment, in order to separate casing soil from com...

Local mesh refinement significantly influences the performance of explicit timestepping methods for numerical wave propagation. Local time-stepping (LTS) methods improve the efficiency by using smaller time-steps precisely where the smallest mesh elements are located, thus permitting a larger time-step in the coarser regions of the mesh without violating the stability condition. However, when t...

Simulation and predictions of material processes at multi-length scales require a detailed understanding of microstructures. While a meaningful study requires large data sets, the size of data sets has been limited due to the lack of automated image processing and mesh generation algorithms. We obtained as images a relatively large population of data from 19 samples of Aluminum foils by Electro...

This paper presents an automated tool for local, conformal refinement of all-hexahedral meshes based on the insertion of multidirectional twist planes into the spatial twist continuum. The refinement process is divided into independent refinement steps. In each step, an inserted twist plane modifies a single sheet or two parallel hex sheets. Six basic templates, chosen and oriented based on the...

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...

Mesh sequences are becoming a common tool in computer graphics as can be seen in video games ormedical imaging. As a consequence, mesh sequences generation’s methods have been developed. Sequences can be created using a modeler or by multi-cameras acquisition. These methods can generate sequences which have different properties. Moreover, different applications using mesh sequences have been pr...
