ElmerGrid 1 2 Step; Starting program Elmergrid Elmergrid reading in-line arguments Output will be saved to file Step. Elmergrid loading data: Loading the geometry from file 'Step.grd'. Loading ElmerGrid file version: 210903 Defining the coordinate system (2-DIM). Loading [4] subcell limits in X-direction Loading [2] subcell limits in Y-direction Loading material structure End of field Loading boundary conditions Found 3 boundaries Loading minimum number of elements Reached the end of command file Found 1 divisions for grid SetElementDivision The mesh is devided into 3 separate subcells. Created 92 radial and 13 axial divisions, total of 531 elements. Loading ElmerGrid commands from file 'Step.grd'. Reached the end of command file Read commands from a file Elmergrid creating and manipulating meshes: 3 cells were created. Numbered 595 knots in 531 4-node elements. Numbering order was and max levelwidth 16. Maximum elementsize is 4.978e-01 and minimum 1.395e-01. 6 element sides between materials 2 and 1 were located to type 1. 13 element sides between materials 3 and 1 were located to type 2. 107 element sides between materials 0 and 1 were located to type 3. Elmergrid saving data: Saving mesh in ElmerSolver format to directory Step. Reusing an existing directory Saving 595 coordinates to mesh.nodes. Saving 531 element topologies to mesh.elements. Saving boundary elements to mesh.boundary. Saving header info to mesh.header. Thank you for using Elmergrid!
