To make the visual analysis of this data easy and efficient, it is important to correctly specify a couple of parameters for each of the zones: Solution Time and Strand ID. Since there are frequently hundreds of time steps, the dataset may contain thousands, or tens of thousands, of zones. This means that unsteady data will have at least one zone for each time step, and may in fact have many zones per time step. The zones may also have different dimensionality for example, there may be a mixture of 3D volume zones that contain field variables and 2D surface zones that contain the problem geometry and surface properties. These zones may represent different areas of the physical domain, the same physical domain at different time steps, or different results that you may wish to compare. What is the best way to represent unsteady data in Tecplot files? As mentioned in my previous post on Data Sharing, Tecplot divides datasets into zones. In computational fluid dynamics (CFD), as with elsewhere in computational physics, the trend is toward modeling of unsteady flows. For computational efficiency we often assume that field data is steady (unchanging in time) but that is generally a simplification of the real physics.

In fact, most data, in real life, varies with time. « Back Unsteady Data in Tecplot Files TecIO and SZL, Tecplot Blog March 26, 2018Īnd so on to viscosity.” –Lewis Fry Richardson.Īnyone who has watched the flow of water down a river, or the vibration of the control surfaces on the wing of an airplane, knows that fluid flow is generally unsteady (changing over time).
