Faxen Correction in DPM Body Force

January 26, 2007, 06:24

I have difficulty in incorporating Faxen correction for my particle tracking code since it has the second gradient of velocity vector. I understand that I need to include "surf.h" and access the cell's fluid variable via RP_CELL and RP_THREAD; but, when I try to interpret the UDF, it shows me an error message in line 35 of "surf.h". Is it true that DPM must be compiled, not interpreted?

Thanks.

yes, most of the dpm macros contains the structure reference ->, for this the udf should be compiled. Interpret will not work in this case.

Hi Davis, did you finally implement your Faxen correction? If so, can you share your UDF? Thx, Alex
