Mesh

OneDGrid( xmin, xmax, nx )

Simple structure to store mesh data from 1 dimension

ThreeDGrid( dimx, nx, dimy, ny, dimz, nz)

Generate a cartesians mesh on cube dimx x dimy x dimz with nx x ny x nz points

• nx : indices are in [1:nx]
• ny : indices are in [1:ny]
• nz : indices are in [1:nz]
• dimx = xmax - xmin
• dimy = ymax - ymin
• dimz = zmax - zmin
• x, y, z : node positions
• dx, dy, dz : step size

TwoDGrid( dimx, nx, dimy, ny)

Generate a cartesians mesh on rectangle dimxx dimy with nx x ny points

• nx : indices are in [1:nx]
• ny : indices are in [1:ny]
• dimx = xmax - xmin
• dimy = ymax - ymin
• x, y : node positions
• dx, dy : step size

get_cell_and_offset( mesh, x )

Get cell and offset

We compute the cell indices where the particle is and its relative normalized position inside the cell

get_x( mesh, i )

Get position
