hi
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, issac_christy@yahoo.in) |
