what's the difference:interpreted and combiled udf
 

About different methods to combile your udf, how can you select it? What is the difference between them?

Many thanks!

Please read UDF manual6.1 Section 1.6 at Page 1-6

It helps.

Rookie.

Compiled UDF's are much better. They are more difficult to implement but it is worth investing the time to learn how to do them.

The most important differences are in capabilities and velocity of execution.

Using interpreted UDF, you can read and write data only using pre-defined macros. This kind of UDF is portable to all platform (Windows, Unix), but they're slower to execute.

Compiled UDF are not portable (you have to recompile them if you change platform), but are faster and offer you complete access to data.

A suggestion: Use UDF for easy tasks like implementing boundary conditions or profiles. Pass to compiled UDF if you have to implement more complex things like a complete model or a scalar equation.
