PPT-Boundary Element Method Stephen Kirkup

Where did it start The mathematical basis of the BEM is in the reformulation of the BEM as a boundary integral equation Eg Kellogs book Foundations of Potential Theory 1929 Availability of computers and the Fortran programming language led to the initial solutions of boundary integral equations in the 1960s. : (extended) . isogeometric. boundary element methods.
