ParaView for Fluid Dynamics

CFD solvers are used in many domains but particularly often in aerospace and automotive engineering. Given the appropriate reader to bring data from your CFD package into ParaView, you have access to a host of post-processing operations. You can of course directly display the computational mesh, with or without computed quantities displayed on it, in surface or volume rendered forms. Parallel streamline filters show overall direction of flow within the data. Besides these qualitative abilities, ParaView lets you pick apart the data – with interactive selections for example, compute derived quantities – with the calculator filter for example, and display the actual data values in text or chart forms. This ability to dive down into the details is important when you want to find out what is happening in the interesting portions of the data.
