* Data given as a 3-columns ASCII files (x,y,value) can be read and interpolated on the model mesh using the [[solvers:scattered|Scattered2DDataInterpolator]]. Natural neighbours interpolation or cubic spline approximation are possible for the interpolation of these data. | * Data given as a 3-columns ASCII files (x,y,value) can be read and interpolated on the model mesh using the [[solvers:scattered|Scattered2DDataInterpolator]].

* Data given as a structured 3-columns ASCII files (x,y,value) over a grid defined by its lower-left corner (x0,y0), its size length (lx,ly) and the number of grid cells in each direction (Nx,Ny) can be read using the [[solvers:Grid2DInterpolator|Grid2DInterpolator]]. The interpolation is bilinear on the grid and efficient due to the structured nature of the grid. | * Data given as a structured 3-columns ASCII files (x,y,value) over a grid defined by its lower-left corner (x0,y0), its size length (lx,ly) and the number of grid cells in each direction (Nx,Ny) can be read using the [[solvers:Grid2DInterpolator|Grid2DInterpolator]].
