Dear my friends:
i need your help. i study the ECFM model with the fluent, when i solve the unsteady problem, if including the equation for flame area density, it will come up a prompt that:
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: #f
but when i exclude the equation for flame area density, it will sucessfully run, where the ignition model is used in my test. And a initial flow field is computated firstly without considering the heat transfer.
if you have the experience on this subject, please help me.
1. what is the solving step of the ecfm model;
2. how to ignite ;
3. why this problem happened;
any help will be very appreciated.
Thank you my friends!
