Hi, guys.

When inputting the polynomial coefficients in FLUENT 14.5 materials dialog box, I find that the coefficients have only 7 significant digits. Unfortunately, the coefficients in my polynomial coefficients have 12 significant digits, so I use two macros (DEFINE_PROPERTY and DEFINE_SPECIFIC_HEAT) to define new materials. The UDF can be compiled in ANSYS FLUENT. However, FLUENT will exit abnormally, once I click the initialize (both standard initialization and hybrid initialization).

The error message and UDF are uploaded. Can anyone anwser me please?

frankly speaking, code seems to be correct,
may be the problem in polynomials...

you may try to add
#include "math.h"
as it may not be included in v14.5 by default.
