Dear foamers,

I am trying to test the icoDyMFoam in openfaom 1.6-ext using an airfoil. What I do is just taking mixerGgi tutorial and replacing geometry (which I
made using pointwise).

But I got 'Floating point exception' error message before iteration starts (see below).

****
Create time

Create mesh for time = 0

Reading transportProperties

Reading field p

Reading field U

Reading/calculating face flux field phi

Initializing the GGI interpolator between master/shadow patches: insideSlider/outsideSlider
Floating point exception

****


Basically I tried to follow the Jasek's slide (link below),

http://www.openfoamworkshop.org/2009...sak_slides.pdf

It seems that I have a problem with generating interfaces.
I generate two separated surfaces (but identical loacation) and specify
them as different boundaries in pointwise. So I am wondering how people
generate interfaces for general grid interface (ggi) applications.

Thanks in advance.
