چکیده
A cell by cell adaptive mesh technique is described and implemented to solve the Euler equations. The adaptive mesh scheme builds upon a staggered grid Lagrangian code similar to the AWE code CORVUS. The mesh is automatically refined in a cell by cell manner using a solution gradient refinement criteria. The method has the automatic response of adaptive mesh refinement but without storing and solving each level separately. Disjoint nodes are used in the transition from fine to coarse elements. Time refinement is not included at present. The adaptive mesh technique produces results comparable to the uniformly fine mesh in a fraction of the computational time.

Moving Mesh Non-standard Finite Difference Method for Non-linear Heat Transfer in a Thin Finite Rod
In this paper, a moving mesh technique and a non-standard finite difference method are combined, and a moving mesh non-standard finite difference (MMNSFD) method is developed to solve an initial boundary value problem involving a quartic nonlinearity that arises in heat transfer with thermal radiation. In this method, the moving spatial grid is obtained by a simple geometric adaptive algorithm ...
متن کاملRadio-adaptive doses effect on HT29 and MRC5 cell lines: comparison in hypo and hyper fractionation regime
Background: The exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. We examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (HT29) and human fetal fibroblasts (MRC5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in HT29, and at the same time...

Fuel cells are potential candidates for storing energy in many applications; however, their implementation is limited due to poor efficiency and high initial and operating costs. The purpose of this research is to find the most influential fuel cell parameters by applying the adaptive neuro-fuzzy inference system (ANFIS). The ANFIS method is implemented to select highly influential parame...

A cell by cell anisotropic adaptive mesh technique is combined with a staggered mesh Lagrange plus remap finite element ALE code for the solution of the Euler equations. The quadrilateral finite elements may be subdivided isotropically or anisotropically in a cell by cell manner. An efficient computational method is proposed, which only solves on the finest level of resolution that exists for e...
