chrisnitk is on a distinguished road
iam christy, persuiing my mtech in thermal engg,Iam new here. For my mini project i have to solve Coutte flow using pressure correction technique.

i made my programme in C using staggered grid and used finite difference method.

when iam calculating my pressure value (i used float value) , since the values are too small it goes to a value of zero and in iterations it gives garbage value ....

how can i tackle too fine small values in cfd ??? is there any methodes or tools for that ...????

plz do help me
(u can send reply's to my mail also,
