Hi friends,

I'm trying to use ADI method in my code (the code uses SIMPLE method by two steps of explicit and implicit) but I do understand it.
Why do I need to apply ADI? because my code is slow and found out that the bottleneck of my code is explicit calculation.

What is explicit section:
This section easily calculates velocities except pressure which would calculated at implicit part and update velocities. The main loops for explicit section is:

For (i=0, i<nx , i++)
{
For (j=0, j<ny , j++)
{
Ubar=  ...  // calculation of velocities without pressure
Vbar=  ...  // calculation of velocities without pressure
}
}

How can I use other algorithm to improve my code calculation speed ?
Any suggestions ?

Dont loose your time with ADI. It is oldfashion.
