interFoam not running

Hello everyone,
I found no error messages related to meshing,setFields etc but as I finally run interFoam it shows something like this

Selecting incompressible transport model HerschelBulkley

Any sort of Help is appreciated. Thanks

Nothing can be told from your post.
Floating point error says the problem, it is because your dividing a fraction by 0 somewhere in your code. Probably for others to help you should explain what your solving, a figure is better and what changes you made in your code.

I managed to get rid of this problem. I have changed the direction of z coordinates and then interFoam runs successfully.

Hi,

I have the same problem. Could you please explain more what you have done to solve your problem?

Thanks and Regards,
Mehrzad

Hi Mehrzad,

I'm not clear with the concept behind this, but I was doing trails to get rid of this error. One of the Trail was, I changed all the z coordinates of Vertices in opposite direction(in my case from pos to neg). After doing that interFoam ran successfully.
