hello everyone,

i am trying to solve continuity equation in cylindrical coordinates using the PDE mode. [2D axi-symmetry]
the equation contains a term involving (1/r)
its showing an error msg that @ r = 0, velocity is "NaN" !!

how to resolve this...???

can i write a separate @ r = 0 ????


any assistance is appreciated.
thanks,

mainak.
