when i modle the field in a nozzle with an injection in the divergence area,the following error suggestion always appears: Error: FLUENT 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: ()

is there any method to find where i should reform. thanks!

I am getting another type of error during my simulation and it stops:

Error: > (greater-than): invalid argument [2]: wrong type [not a number] Error Object: nan

can anyone tell me why this alos occurs ?

Thanks.
