Mesh

TwoDGrid( xmin, xmax, nx, ymin, ymax, ny )

Simple structure to store mesh data from 2 dimensions

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
