I currently try to implement a level-set equation into OpenFOAM for a simulation of flame propagation.
As I see Bitan probably used a structured grid for the gradient calculation within the reinitialization of the distance function and implemented an own discretization scheme for the gradients (WENO).

Can anybody give me a hint how I could deal with the reinitialization of the distance function on an arbitrary unstructured mesh?

My Problem is as follows:
During the transport equation step I actually solve as first test the simple equation

fvm::div(phi,gmean) == 0

In a second reinitialization step I have to solve the equation mag(grad(gmean)) == 1 for all regions where gmean!=0 to reinitialize the distance function.

My problems is now that I use zeroGradient for the boundary conditions of gmean during the transport equation step which is not valid for the reinitialization. How can I deal with the patch gradients in that case? Has anybody done anything similar?

Matthias

Yes, I have done level set. M
 

Yes, I have done level set. Make two fields, with different boundary conditions. Run the normal solver on the first, reinitialisation on the second and copy the result.

Enjoy,

Hrv, thanks a lot for your qui
 

Hrv, thanks a lot for your quick reply.
Yes your idea is straight forward.
Can you give me a last hint? Is there a boundary condition already implemented which will fit for the reinitialisation? Cause I need neither fixedGradient nor zeroGradient, it would be a kind of fixedMagGrad, wouldn't it.

greetings,
Matthias

Hi,

I am wondering if anyone here has successfully implemented Level Set into OpenFOAM and is willing to share the code?

Pei

Look for Shu, Stephan papers. They implemented the code in OpenFOAM
Dhir too, but not in OpenFOAM.

Hello,
has anyone managed to implement the level set formulation as proposed in the paper by shu?

1)In particular, have you managed to implement the the gradient term (eq (11-12)) for the reinitialization procedures?

2)and also, I have some strange velocity pressure peaks at the interface whenevr the interface change cell, has anyone had the same issue?any solution?
The error come sprobably to some non smoothnes of the rhoPhi term, or nu but I can't solve it..(yes, i applied smoothing as suggested..)

Thanks,
Matteo
