Semicircle boundary is build using approximation of curved boundary with square cell (see attached picture). > Why do you need a Cartesian mesh?

I need Cartesian mesh, because I want to test new method for solving pressure correction equation, and it works only on Cartesian mesh. > _______________________________________________ > fipy mailing list > [email protected] > http://www.ctcms.nist.gov/fipy > [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ] -- Sincerely yours, Tatiana Gornak
