Hello,
I am looking to change the dimensions of the cantilever beam (beam3d.grd) from "loaded elastic beam" tutorial/Elmer GUI. I tried modifying the subcell sizes in .grd file -
##### ElmerGrid input file for structured grid generation ######
Version = 210903
Coordinate System = Cartesian 3D
Subcell Divisions in 3D = 1 1 1
Subcell Sizes 1 = 0.8590488504
Subcell Sizes 2 = 0.53719646
Subcell Sizes 3 = 10.77308811
But when I click on model summary, the bounding box lists the the original dimension of the cantilever beam - 1 m x 0.1 m x 0.05 m (L X w X t). How can I modify the dimensions?
Thank you for any information you can provide.

Re: Cantilever beam - Modifying dimensions
I used ElmerGrid to convert your file to an Elmer Mesh and had no issue. You may be loading the old mesh because ElmerGrid puts the new mesh in a subfolder.
FINITE ELEMENT MESH
Mesh dimension: 3
Leading element dimension: 3
Nodes: 6073

Thanks, Kevin!
I am still novice when it comes to Elmer. Could you tell me how you used Elmer Grid to convert the file to an Elmer mesh? Also, which sub folder is it stored in? Thanks again!

Re: Cantilever beam - Modifying dimensions
From the command line in the directory you have the grd file you can type the command
ElmerGrid
without any options it will print the help file to tell you what the options are
grd to elmer mesh is
ElmerGrid 1 2 meshname (where mesh name is whatever your grd file is named)
it puts the Elmer mesh in a subfolder named meshname
