Hi. I am getting following error when my DPM model run after 20 flow iterations.
Can anyone help me to understand this error and how to avoid it. Error: FLUENT received fatal signal (STACK_OVERFLOW) 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: () |

Thanx Amir for replying.
Currently Fluent is installed on C drive where 56 GB is free. I have 3 GB RAM. When i run my case then i noticed that my ram utilization does not go above 500 MB. I have dual core process with 2.0 GHz each processor. I m doing coal gasification modeling using finite rate modeling with DPM. Is there any problem with my case setup causing that STACK_OVERFLOW error? At lower mesh size (less than 2000 cells) that problem is not there but then i m not getting converged solution till 50000 iterations. Kindly give some suggestion. |

Dear Sir Amir
My case and data files are in F drive where almost 40 GB is free. Moreover i have tried to solve my problem at various other computers with different specifications but for this particular case same error appeared at all computers too. Further if i changed my case with Non-pre mixed model and DPM then there is no any issue and problem is converged. I think there is some problem associated with DPM iterations to Reactions (i have set 9 hetro and homogeneous reactions). Thanx for giving me time. Hope you will say more on my problem. Regards |
