Derivatives
 

Hi , In the coupled solvers.you can compute first dervatives of velocity, temperature and species.(look documentation FLUENT.INC\fluent6.0\help\index.htm ).

BUT for my case when i want to derive the temperature a message error>(Error: Floating point error: invalid number information:cx-solution-plot: No data points in range.). please how can write and display the derivative of tempearture . thank's
