Detailed Description

construct the solution class by giving at a minimum the domain on which to solve the equation

[virtual]

[pure virtual]

solve the problem and return a pointer to the solution. beware : when the problem is deallocated, also the memory where the solution resides is freed

construct the global stiffness matrix, by adding the correct local stiffness matrices If done before, init global stiffness first !

construct the global force vector, by adding the correct local force vectorterms per node If done before, init global force first !

return the present value of the sparse matrix for node I (row) and J (column)

return the present value of the force vector

init the Stiffness quickly, necessary before you do a second assemble

init the Force quickly, necessary before you do a second assemble

return a pointer to the net on wich we solve a problem

print solution (unknowns) to a certain file, given by its name, eg /home/me/k2dgrflow/data.u

print stiffnessmatrix A from A x = f to a certain file, given by its name, eg /home/me/k2dgrflow/data.a

print forcevecor f from A x = f to a certain file, given by its name, eg /home/me/k2dgrflow/data.f
