Ideal Flow Solution Comparison over a 90-Degree Angle Point Using CVBEM and FEM

Complex Variable Boundary Element Method (CVBEM) is an emerging numerical approach for simulating flow problems, including groundwater flows. Benchmarking the solution from CVBEM with other established approaches, like the Finite Volume Methodologies (FVM), will showcase its reliability. In this work, the flow fields from the CVBEM and FVM are compared for an ideal flow over a 90-degree angle point. The comparison focuses on the flow vector’s magnitude and direction. This test problem was chosen to showcase the reliability of CVBEM for groundwater flow applications. The close agreement between the two results underscores the accuracy of the CVBEM solution.
