I am a new user in Gerris world and i have a question a bout the first example Cylinder.gfs
My question is How can i know the original point in gerris 0 0 0
if i would like to move the solid cylinder in a certain coordinates ??
Is the 0 0 0 point is the centre of the cylinder?.... if its ....what is the empty distance before the cylinder?......as i want to have an output after the cylinder body and i want to compare the result in certain point with other software so i need to know exactly how can i define the original points 0 0 0
