VBB advisory provides advice based on Computational Fluid Dynamics (CFD), Finite Element Method (FEM), and Discrete Element Method (DEM) on a broad range of engineering problems. There are many possibilities, including, but not limited to, structural analysis such as deformations or fracturing, thermal effects like temperature fields or thermal expansion, and calculations on the behavior of liquids, gases, and particle streams. Results are obtained using industry-accepted open-source software like OpenFoam, Calculix, and LIGGGTHS.
