Hi. I'm using a DEFINE_INIT macro in a compiled UDF for my simulation of greenhouse ventilation.this macro should initialise two User Define memories with a temperature (C_UDMI(cell,thread,0) and a mass fraction of vapor water (C_UDMI(cell,thread,1).After compiling my UDF, I try to hook this function thanks to the "function hooks" panel.But when I start the solver, an error message tells me to close Fluent and restart...I dont' know where is the problem can somebody help me please? thanks

the exact name of the error is: FLUENT received fatal signal (ACCESS_VIOLATION)

The ACCESS_VIOLATION is a generic error report in Fluent 6 (and reads the same as ACCESS_VIOLATION error in Fluent 4, which is written in Fortran).

From my experience, you normally get this error when you try and access a variable that has not been properly initialized or is not accessible in your function. I would check this accordingly, perhaps with a very simple bit of code.
