Help on the ECFM model of premixed combution
 
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:
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: #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.
FOR EXAMPLE:
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!
