mayank.dce2k7 is on a distinguished road
Hi,

I was running a lagarangian particle case using 'icoUncoupledKinematicParcelFoam'. I observed that no matter what dimension you give to 'g' in dictionary the solver works correctly.

My another question is: Does units matter when you specify force expression for value.Su(), like the one below:

Code:
value.Su() = mass*g_*(1.0 - p.rhoc()/p.rho());
I checked by changing the code to:

Code:
value.Su() = mass*g_*p.rhoc());
It still works although the units are inconsistent i.e not equal to that of force.


Regards,
Mayank
