GDS File format Basic properties of GDSII Integer Database : basi unit - nanameter (10^-9 meter), 정수 좌표 표시, 2^-31 ~ 2^31 Hierarchical : elements 가 cell/structure 로 group 화 되고, 중복하여 여러번 배치 됨. (효율적임) Cell 은 무한히 nested 될 수 있음. 5 GB 로 Polygon 10억개 표현 가능. Entity 의 실제 좌표를 얻으려면 nesting 을 역산해야 해서, 오래 걸림. Binary : compactness 를 위해 binaray 사용. ASCII 와 equivalnet 한 공식 binary format 없음. 다양한 회사들이 자체 binary-ascii converter 보..

Gmsh - Gmsh 로 mesh 짜기 Want to easily Make advanced detailed Hex mesh in Gmsh? | Numerica.pt Want to easily Make advanced detailed Hex mesh in Gmsh? On some commercial applications meshing is integrated like Ansys or Fusion 360, however on the open source landscape a mesh generation software is developed separately from the solver. Gmsh works w… numerica.pt
유한요소 해석 유의점 A person using the finite element analysis technique must examine the solution analytically in terms of (1) numerical convergence, (2) reasonableness (does the result make sense?), (3) whether the physical laws of the problem are satisfied (is the structure in equilibrium? Does the heat output balance with the heat input?) (4) whether the discontinuities in value of derived variables across elem..
