While finite volume methodologies (FVM) have predominated in fluid flow computations,\nmany flow problems, including groundwater models, would benefit from the\nuse of boundary methods, such as the Complex Variable Boundary Element Method\n(CVBEM). However, to date, there has been no reporting of a comparison of computational\nresults between the FVM and the CVBEM in the assessment of flow field\ncharacteristics. In this work, the CVBEM is used to develop a flow field vector outcome\nof ideal fluid flow in a 90-degree bend which is then compared to the computational\nresults from a finite volume model of the same situation. The focus of the\nmodelling comparison in the current work is flow field trajectory vectors of the fluid\nflow, with respect to vector magnitude and direction. Such a comparison is necessary\nto validate the development of flow field vectors from the CVBEM and is of interest\nto many engineering flow problems, specifically groundwater modelling. Comparison\nof the CVBEM and FVM flow field trajectory vectors for the target problem of\nideal flow in a 90-degree bend shows good agreement between the considered methodologies.
