I'm trying to use the multilevel B-Spline tool by SAGA in order to interpolate some points and create a raster image.

But sadly while the process is running, QGIS crashed without any error message. Maybe it's because of my computer that doesn't have enough RAM. I have 4 Go RAM, how much RAM do you have?

Maybe if I enter values that need less ressources, I could create something even if it's not a raster with a high quality. Does someone know what does the parameter do and which values I have to enter to use the lowest RAM?

Here are the fields I have to inform:

Multilevel B spline interpolation options to choose

(With "Fit" I can only choose between "Nodes" and "Cells")

I use QGIS 2.18 on Ubuntu 18.04.
