I have a few questions about some schemes: The definition of: Code: ```Code: div(phi,csi) Gauss limitedLinear01;``` tells me that I am calculate csi with gaussian 2nd order and bound the variable from zero to one - is that right? So what do I limit? The gradients of csi or the value of csi? Can I write the above definition like: Code: ```Code: div(phi,csi) Gauss limitedLinear 0 1;``` ??? or are there any differenzes? I refer to the UserGuide. If that`s correct, I do not understand the following: Code: Code: `div(phi,csi) Gauss limitedLinear01 0.25;` In my opinion I ll bound csi from zero to 1 and additionally to 0.25 ? But I know that my interpretation is wrong Looking forward for a few comments And thanks in advance Tobi
