Dear Raymond, Jonathan and Dan, Thanks a lot for all your replies.
Indeed this works ! Setting the diffusion coefficient to all interior faces helps a lot. Thanks for your help once again.

Seconded, remember that the coefficients at the faces need to be zero to not have propagation. This will require masking the faces based on position. -- Daniel Wheeler _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ] _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
