How to Include Exponential in UDF
Hi i am writing an UDF for heat flux which includes an equation, in that equation i have exponential factor, and i have wrote that UDF, while compiling that UDF its showing an error in exponential factor, so can any body tell me how to solve this probelm.

exp(number)

I think default fluent compiler will not solve exponential funtion..for that you may have to install visual c+ +...
or instead of going for exponetial function..u can give the 2.718^(some corelation) 
Re: How to Include Exponential in UDF
you can use the function (double) exp(double x) remeber x is defined as a real type in udf

Hi CDE, Jay, and Wang thanks for ur attention, i am not getting clear picture, so pls can u tell me in detail.
My equation wil be in the form of e^2x, so how to give this as input to fluent compiler.. Thanks.

exp(2.0*x)
