FYI, the problem does not seem to be related to variable subdomain restriction... If we take out the subdomain-restricted variable completely, we still see the issue. Note that the periodicity of v is set up with two sets of periodic BCs (one for the left and one for the right half of the domain) so it could have to do with a pair of periodic boundaries meeting at a point? -- John ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
