FE-BUI – Finite Element Beowulf User Interface: A homemade package for automated parallel finite element computations. A computational package, the FE-BUI, is introduced for automated parallelization of finite element codes. The package has been developed at the Computer Center of the School of Chemical Engineering of NTUA. Its scope is to provide the ability for parallel execution of serial codes on Beowulf clusters, in an easy and efficient way.
