Default DPM Converging Problem

Hi, I am working on a DPM solid-liquid Simulation but having problems with the continuity and x-velocity residuals they never get to convergence criteria...

I'm working with coupled implicit solver...

What could be happening?

Check your grid for fineness and skewness. Go through Smooth-swap process if you haven't. Are you doing transient analysis? Why not are you using segregated solver?

Cheers.

Hi, thanks for your advise, I already did that grid checking...

About the analysis, yes, I am doing transient analysis...

On the other hand, the calculation of the erosion rate through the pipe is the final purpose of this simulation and to do the display of this calculation I need to use the coupled (implicit or explicit) solver…. But I have already worked with this Segregated solver and had no problems, even the calculation is really faster, only the fact of not seeing the display of the erosion calculation is the limitation I had with it...

Did the grid is thick-long sypt? If so ,you should choise the versions as 2ddp for two-deminsional or 3ddp for two-deminsional in the frame of "FLUENT Version". try it please!

Yes, the grid is thick and long and I am working in the 3ddp fluent version....

Another idea???? please????
