Does anyone know, what the different between compiled and interpreted udf is? I can interpret my udf but can't compile it. Can I just do one of those?

u can check the udf manual..given below is the link

I am still trying to compile the udf example given in the fluent tutorial. I am getting confused. How to determine which udf should be compiled or interpreted.

what is the case u r trying to set up and whats the purpose of the UDF in the model? Then i will be able to help u.

Initially, I am trying to simulate a simple phenomena, a ball drop in the air until it reach it's terminal velocity. Later, I would like to simulate a water droplet falling and hitting a flat surface and simulate the spreading phenomena. Thanks.

I checked in Fluent manual it says, for GRID_MOTION macro, it can only be executed as compiled UDF. I am stucked with this compile problem for about 3 weeks!!! I am using window XP and Visual C++ Toolkit 2003 as my compiler. I've set my environment and declare my working folder as sharing as per recommended by Fluent. I am still getting 'nmake' is not recognized as internal or external command. Thanks for yr help.

good..atleast u now know its shud be compiled for sure. next thing is to make sure what macro to use. mebbe in ur case define c.g motion is more appropriate. not sure though. finally, did u start fluent from ur working directory only before compiling it? that is as important as having the compiler itself. in case u have problem, go to programs ----> fluent inc ----> environment, then click modify. then it shud allow u to open fluent from a command prompt in whatever directory u r. hope, all this helps. if u r working in a company get the admin to install visual studio .net on ur machine which is much much easier to handle.

I've set the environment and started my fluent from the compiler command prompt. Previously I am using microsoft visual c++ toolkit 2003 (compiler) that I downloaded free from the internet. Today I want to try to install visual studio.net. I hope after this, it could compile.

Thanks to all of you. Now my fluent is working fine. I install Microsoft visual c++ (b4 this I was using microsoft visual c++ toolkit 2003).
