EFG programming

 Prof Dolbow/Prof N. Sukumar/Someone working in this field  

While I was going  through your(Prof. Dolbow's) EFG program using MATLAB for 2D problem, I could not understand why classical anlytical equations for displacement were used in taking care of displacement boundary conditions(step no.11, forming q vector and G matrix).I feel that there is something wrong here. We resort to computational methods when analytical solutions are not available.What shall we do in such situations?Others may also help me to understand this.

Thanks.
