Floating Point Error

Hi Everyone,

I have been trying to simulate a complex flow involving some UDF. The UDF works well for a certain part of the calculation (eg: Wood pyrolysis) but I get a floating-point exception when I try to use it for the oxidation of char. I have attached the error file and the part of UDF that is used for the oxidation process. If anyone knows what might cause this error it would be of great help. I have attached the image for your kind reference.

Regards,
Michael Navamani
