hi all,

i am investigate some time for the numeric schemes to understand things better.
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
