Problem with DPM injection!
 
Hi all! What does this error message mean? "cant figure which cell is going to... Aborted". Solver displays this message when it reaches dpm iteration. I tried different types of injections and positions, it doesnt help... Thanks

Hi

If "Aborted" appears for a droplet, it means that the solver's iteration limit is exceeded before it can determine the fate of the droplet. One possible remedy is to increase the number of continuous phase iterations per DPM iterations in DPM panel.

Hi! Thanks for the answer, but it seems that solver doesnt iterate at all. the error appears instantly and no particle tracks are available. thanks again

Make sure initial particle positions are within the domain.

Hi! Thanks for your interest, but that was the first thing i did when received error message. It is ok, it is inside the domain. Can it be due coinsidence of the injection point and of a node?

Problem with DPM injection!
 
hi I have some problem with my DPM injection because am trying to simulate the heavy fuel oil combustion, but it does not occur, somebody tell me an experience with this proble. Thanks Daniel Santana

Re: Problem with DPM injection!
 
Hi! Try starting your simulation with simple water or any individual substance like ethyl alcohol, then chek out for heavy oil. By the way how do you define your oil properties? Do you represent them as narrow fractions with specific properties that form a mixture, or do you inject thm separately?
