I have two questions, the first being pretty basic but having a bit of a headache with it:
1) Could anyone teach me how to set the colouring of the air (gray gradient) in Paraview so I get the same result as the multi phase dam break?
2) The second question is about a feature I found described in here:http://dual.sphysics.org/2ndusersworkshop/2016/Crespo_PPT_2ndUsersWorshop_POST_2PDF.pdf
On page 22 "tracerVTK" is shown - I have not been succesful finding documentation on how to use it - could anyone show me or kindly tell me how I can read more about using it? And does it function with 2D simulations?
