Dear all,

I have written a code ( in fact it is a software) for 3D finite element structural analysis. While developing the code I found that assembling global stiffness matrix is quite complicated. The complication is even more when we want to reduce the degree of freedom of some of the nodes. Also for giving boundary condition, when we set one or two components of deformation rather that all the three. Now these parts of my code has become so complicated even to myself.

My code works well now but I am wondering if the complexity is usual or if I am doing the job in an ineffective way. Since I have not discussed my methods with anyone else, I thought it would be helpful if I post the problem here. Perhaps some of you have experiences to share.

Regards,

Hassan
