Hi all,

I'm getting the error as follows:

C:\PROGRA~1\ANSYSI~1\v145\fluent\fluent14.5.0\win6 4\2ddp\fl1450s.exe received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

I've got someone answered like
"here are several causes which we will discuss.

For example, in a UDF, you may probe the cell temperature using the macro C_T(c,t). However, if you have not turned the energy equation on, then there is NO temperature stored, and you will get an ACCESS_VIOLATION.

To check a Thread for whether a variable is stored on it, you can use the THREAD_STORAGE(t, SV_XXX) macro, where SV_XXX is the storage variable for the equation of interest. For the energy equation, you would use SV_T. This macro returns a pointer to the data. The value is NULL if the data is not available. See storage.h for a complete list of storage variables.
Another cause for the macro is that your case has a UDF hooked, but you do not have the UDF available. The solution is to make sure you have the UDF directory in the correct location relative to the case file. "

I'm pretty sure that I can exclude the second cause. But how to use the THREAD_STORAGE(t, SV_XXX) macro? Do I need to write a new udf or something? How?
