What is the difference between explicit scheme FTCS, Dufort-Frankel, & Adam-Bashforth method?

Question

I am trying to write a program using FORTRAN to solve the following CFD problem:

du/dt = alpha * ( d^2u/dx^2 + d^2u/dy^2 )

using the 3 methods mentioned above. I would like to know what is the characteristics of each method used under the same circumstances by making comparison among them.

Also, the program that I have written shows the longest time for FTCS method to be calculated compared to the others. FTCS being the simplest method among the 3 methods, but how come it takes longer?

Can anybody help...?

Congratulations" you have easily by utilising your query have been in a position to instruct by utilising their incoherent ramblings the psychological state of the severe fundamentalist. As for various Christians that would desire to truly require a e book to have the skill to describe the adjustments. yet right here that's in as brief of way i'm able to respond to. For the 1st 1500 yrs there have been the Catholic and diverse Orthodox church homes who have been at one time excepted the Bishop of Rome as first between equals with the Latins (Catholics) coaching and believing he exchange into head of the Church by utilising decree of Jesus whilst he pronounced thou artwork Peter (meaning rock) and upon this Rock i'm going to construct my Church and that i will supply to you the Keys to the dominion etc: the justifications the 1st Christians extra or much less that went there separate techniques is somewhat with some ameliorations a determination made the place as some such because of the fact the Greek Orthodox desperate that the Bishop of Rome had no authority over them you will say it exchange into like a little one telling a Aunt or Uncle you won't be in a position to tell me what to do purely my mom and dad can. additionally there exchange into some disagreements over what or how one would desire to have faith. Then approximately 1500 yrs after Christ based his Church the Protesters stood up against the Catholic Church claiming it had lengthy gone off beam from the Bible and began coaching a diverse way.there isn't any argument by utilising Catholic scholars and Historians that there have been Catholic bishops and Cardinals not performing the way the Church required and that they introduced scandal on the Church and the inability of tens of millions of contributors. The Church has corrected it somewhat is misunderstood teachings and has made it impossible for it somewhat is teachings at the same time with indulgence to be abused by utilising undesirable clergy back. Now we paintings with maximum Protestant church homes on many stuff and in direction of a reconciliation of the two faiths. yet there are the radicals the extremist on the two facets yet people who're the worst are the Fundamentalist at the same time with David and his form. Then there are people who get there concepts from Jack Chick guides that's yet another hate crammed team claiming to be Christian yet are any element yet..
