Region Boundaries on a Trianguiar Grid Slagpub
نویسنده
چکیده
A simple graph model is developed for binary digibl pictures on &triangular grid leading to consistent and intuitive definitions of connectivity and region boundaries as well as fast memory-efficient algorithms for computing boundaries and the "insidedness" tree. Boundary encodings are extremely compact and can be smoothed using a discrete implementation of minimumperimeter polygon methods. Attempts to generalize the model to nontriangular grids explain the well-known "anomaly" associated with connectivity on the square grid.

Modified Fixed Grid Finite Element Method in the Analysis of 2D Linear Elastic Problems
In this paper, a modification on the fixed grid finite element method is presented and used in the solution of 2D linear elastic problems. This method uses non-boundary-fitted meshes for the numerical solution of partial differential equations. Special techniques are required to apply boundary conditions on the intersection of domain boundaries and non-boundary-fitted elements. Hence, a new met...

متن کاملNumerical Simulation of Flow Past Oscillating Airfoil Using Oscillation of Flow Boundary Condition
The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...
