Hello,
where can I find references for the limitedLinear scheme to cite in a paper?

Thanks in advance,
Alberto

There is no printed reference but it is Henry's application of the Sweby limiter to central differencing.

Thanks Mattijs.

After looking into the code I found in limitedLinear.H:
...
return max(min(twor, 1), 0);
...
with "twor" beeing equal to 2*r for default setup, e.g. "div(phi,B) Gauss limitedLinear 1;".
For me this limiter looks very similar to the minmod limiter instead of the factor 2:
minmod: return max(min(r,1),0);
The Sweby limiter reads max(0,max(min(beta*r,1),min(beta,r))).
I wondering why this modified limiter is used because due to the factor 2 it lies on the opposite limit (lower left) compared to the minmod in the Sweby diagram.

Hello everyone.

As a newcomer I have two concrete questions concerning two div-schemes:
- Gauss limitedLinearV 1 and
- Gauss interfaceCompression.

I suppose that the interfaceCompression scheme does some blending between UD and CD, based on the blending factor (limiter) calculated according to either quartic or quadratic formula. Is this true? Or where is the limiter for this scheme used?

In limitedLinearV, I suppose that it is a kind of limited CD, but how is the scheme limited? Where is the limiter for this scheme used?

Is there any written text about these two schemes, or can anyone shortly explain me how they work?

Many thanks in advance, best regards.

Why does the limiter in limitedLinear look like

max(min(twoByk_*r, 1), 0);

with twoByk_ = 2/k_ where 0 < k <1

when Sweby limiter is max(0,min(beta*r,1), min(r,beta)) with 1 < beta <2 ?

From what I can see this is not the same.

Hello,

I'm working with limitedLinear and I'm also trying to understand the limiter.
Have you found any informations about it?

Thank you.

Hi to all,
I'm working with this limiter too and I would know if anybody found some information about it.

Thank to all
