need help regarding error in surface rxn UDF
 

Hi, Has anybody implemented multiple surface reactions through UDFs.

I am modelling a system with multiple surface reactions. Right now I have written UDF only for one reaction. The compiler doesnt return any error. I have checked for all the values return by my UDF, none of them are 0 or nan or inf.

Still the fluent doesnt run the program. This is the error given by the solver.

Error: > (greater-than): invalid argument [2]: wrong type [not a number]

When does this error appear.

Any help will be appreciated.

Thank you Ashish Jain
