Hello all,
I am trying to use an UDF in Fluent 6.3. This UDF works very well in Fluent 14.5 but when I want to use in Fluent 6.3, I have recieved an access violation error. The problem is due to UDM that is applied in the UDF; but I do not know how I can solve it. when I ignore UDM variable, UDF works very well in Fluent 6.3; but by adding UDM, I have recieved the violation error again. Moreover, the mentioned UDF has been compailed without any error. |

Hi,
Could you give some more details? According to me, access violation happens when FLUENT tries to access something that is not there. Ex: while calculating gradients (if written in Define Adjust), in the first iteration, an error will come as no gradients are stored, so it is advisable to attach that UDF after 1-2 iterations.

Hi,
thank you very much for your answer. My problem is how can I use UDM(user defined memory) in Fluent 6.3? Fluent 6.3 can not access to UDM value; whereas, its value is defined in UDF. Quote:
