The easy path is probably reinstallation of Visual Studio (taking special care to make sure that the command line interface is set up properly), but the reinstallation path is always perilous. Finally, keep in mind that if you do something really bad, you may need to restart Fluent before even a fixed UDF will work. How can I avoid it? I am investigating the wave propagation in a tube with a Helmholtz resonator attached to one end by using CFD. http://epssecurenet.com/floating-point/floating-point-exception-c.html

To avoid this problem, you will have FLUENT perform a small number of iterations, and then you will set up the monitors. Here are some suggestions to avoid this problem: Make sure your question is as clear, concise, and as specific as possible. In order to compile your UDF, Fluent needs to know where the nmake program is located, and it currently can't find it. Generated Sat, 15 Oct 2016 23:24:03 GMT by s_wx1131 (squid/3.5.20)

How do I set boundary conditions? The time now is 17:30. Save the data file ( airfoil.dat). To hook your UDF into Fluent, you'll probably have to use one of the DEFINE_* macros that Fluent provides, and this is most easily done using C.

What is important to consider I would do it that way: 1.
