> Dear Ashish Singh,
> the messages you get in the error files are geometry problems.
> As a general rule, it is not recommended to have primary particles
> starting exactly on a boundary, because of possible rounding problems (is
> the particle in region VOID or in region WALL?). The source routine takes
> care to solve most of those problems making use of the particle direction
> (few last lines in the source.f code). However, in some cases, you have
> particles starting on a boundary..with a small rounding : for instance,
> x=-210.000000000002 instead of x=-210.). this causes a mismatch between
> initial localization and tracking. The code is able to solve the problem,
> but it issues a warning message in the err file.
