Hi everyone,

I am trying to implement level Set Method in OpenFoam, but I got this error in pEqn.H.

I have not changed anything in "pEqn.H" or related to that.


Any advice?

Hi,

I can recommend to build a OF-Version with debugging enabled. That helped me with the same kind of error

http://openfoamwiki.net/index.php/Ho...UG_-_libraries

your problem might be a division by zero, or infinity or a multiplication of fields of different size. I also thought the problem was in the pEqn.H but i turned out it was a lot earlier..

Greetings
Nicklas

Hi Nicklas,


Thank you for the reply. I found out the error using nemiver. There was a mistake in defining Heaviside function which gave an error in pEqn.H. Now everything's working fine!!..



Thanks,
