The results can vary significantly with the value of c - the shape factor. Try different values to see what occurs with regards to stability and consistency. This is still somewhat unknown and generally done through trial and error. 

@Joe Riel 

Joel, you are correct - eqn 3 got duplicated as eqn 4. Eqn 4 should be the MQ trial function - which also shows up in final form as Eqn 5.  

 

Dr. Subramanian,

We also address 2-D and 3-D, and include finite element code listings in MAPLE and MATLAB for heat transfer, stress-strain, and fluid flow (for forced as well as free convective flow in 2-D). There is a website that can be reached through CRC Press that will allow you to download codes, including FORTRAN listings, as well as power point slides (an online course has been taught for some years now at UNLV) including a complete set of homework problems with solutions. A series of videos were also prepared but may be restricted to only UNLV. I am not using fsolve - in fact the programming is rather primitive, but done so to illustrate concepts and principles. Suggested improvements are welcome! There is a chapter of the boundary element method (with codes) and the chapter on meshless methods. My other book with Dr. Kassab and Dr. Divo, published by ASME Press, contains additional details regarding the meshless method.
