I don't see anything obviously wrong in your script. I do find your problem is strongly sensitive to the thermal diffusivity in the fluid, so small changes in any of tc0, den0, or cp0 can change the temperature the wire achieves at any timestep. Beyond that, I don't know. _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
