Many simulations within the field of renewable energy involve the coupling of different physics. An exemplary example is the analysis of a wind turbine. Here the structure (blades, tower, generator, gearbox, etc.) is interacting with the fluid.
Pointwise gives you the ability to manipulate practically every aspect of your grid. Although this provides the ability to devote attention to the object being studied – the airfoil, turbine blade, or in this case, a landing gear assembly – it can be a cumbersome interactive task to select entities to modify individually.

Appropriate grid generation is a key aspect to obtaining a high quality CFD solution in an efficient manner. Inspection of grids to assess element quality, grid density, and grid placement is critical to the setup of computational models. In this article, we will highlight three common tools you can utilize in EnSight: coloring grid by element type, mesh display attributes, and element metrics inspection.
Are engineers actually making design decisions based on simulation results? The 2013 State of Simulation Driven Design Report, written by Chad Jackson, says yes. But there are some surprises in the data. Our overview of this special report includes an opportunity for you to order, at no cost, the full report for your own in-depth reading.
