Default Help with UDF

Hi, can anybody help me out with this simple UDF. It compiles and loads fine but I keep getting the ACCESS VIOLATION error when iteration starts.

The UDF is as follows:

#include "udf.h" DEFINE_ADJUST(temp_cell, d) {

Thread *t;

cell_t c;

thread_loop_c(t,d)

{

begin_c_loop(c,t)

{

C_UDMI(c,t,0) = C_T(c,t);

printf("temp pared [C] = %f\n", C_UDMI(c,t,0));

}

end_c_loop(c,t)

} }

Thanks

Did you remember to set the the user defined memory?

Mark, thanks for your help. I have now set the memory locations to 100 (I don't know whether this is too many locations or not)and apparently is the UDF is working (at least the access violation is gone) The thing is this UDF should print the cells' temperatures to the console window but nothing happens. Any idea of what may be going on?

Blas,

1. in your code you have

C_UDMI ...

this is the User Defined Memory, and since you only have one (referred to by the last entry in the array of C_UDMI, i.e. 0), recall C and C++ arrays start at zero, set the number to 1, not 100.

2. Try 'Message' instead of printf.

This should work

i.e. Message("hello world");

Mark
