If you are working with a vector field (now on VectorField) in ParaView and you need to create a contour graph that requires contour levels instead of a continuous field (figure 1), then you have two options. First idea resembles the contourf command of MATLAB.
Analysis, in mathematical sense, is a key tool for understanding natural phenomena which helps scientists to explicitly express the governing physical relations. It is an inherent part of physics because our perception of nature has evolved around differentiation, integration, series expansion and so on. Hence, up until the last century,
Computational fluid dynamics (CFD) has recently become a crucial tool for engineers to model industrial processes, conduct comprehensive engineering analyses and design more efficient production lines. Utilization of CFD has been beneficial by minimizing the endeavor for time and source consuming experimentations.
