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. Yusik |
