An improved procedure for solving transient heat conduction problems using the boundary element method

摘要: In employing the boundary element method to solve transient heat conduction problems, domain integrals need be calculated. These can calculated either by directly discretizing domain, or indirectly utilizing a time-marching scheme which requires time integrations evaluated from initial time. Although second approach overcomes for discretization, it has disadvantage of requiring large storage and CPU increasing number steps. This paper is concerned with procedure approximates without discretization. The employed so that at particular known weighting temperature distribution. then utilized approximate similar different weighting. It shown proposed dramatically reduces requirements time, even small divisions.
