Cavitation in a high-energy water injection pump is the phenomenon investigated in this case study that shows how it’s often necessary to use multiple tools for complex problems. Thermodynamics of vaporizing fluids, single-phase, two-phase, unsteady, acoustics, … the problem is not short on challenges.

When running simulations in a viscous flow no-slip conditions mean the boundary surfaces in your simulation results will have zero velocity. What if you want to draw surface-restricted streamtraces to understand how the fluid flows within the boundary layer near the wall? Read this article to learn how Tecplot finds the volume zone that neighbors the boundary and uses velocity gradients to calculate streamtraces on the surface.

There are lots of ways to control the size field in your grid. Proximity-based influence can be subtle and – if not implemented right – troublesome. Watch this video to learn how you can ask Pointwise to include the effect of this aspect, and why it’s often useful.
