Hi Bob,

Can you provide some information on how you produced this error.

It may be worth reading up on how the Prandtl number is used in PHOENICS: http://www.cham.co.uk/phoenics/d_pol..._p.htm#prandtl http://www.cham.co.uk/phoenics/d_pol...c_p.htm#prndtl

Hi,

This error can happen when solving the energy equations, but I would need to know more to fix it. Can you post your q1 and results file or send them to rd@cham.co.uk.

Thanks
