Tecplot 360 hangs during movie creation when running tec360 in the background

Problem: Tecplot 360 appears to hang at the end of movie generation running ‘tec360 &’ (running 360 in the background). This is a known issue with the FFmpeg executable, which Tecplot 360 uses to create movie files. Solution: Include ‘-nostdin’ to the AVI, WMV, or MP4 Format Options in your tecplot.cfg file to avoid a FFmpeg hang if you’re running tec360 on Linux in the background. For example: $!ExportSetup MPEGFormatOptions […]

Understanding and Automating Viewer Position Angles

Problem: How do I change the viewing angles Psi, Alpha, and Theta from the viewer’s perspective? Also, please help me understand how these angles are defined. Solution: Below is a diagram from the 360 User’s Manual describing how Tecplot defines Psi (Ψ), Theta (θ), and Alpha (α). The following exercise uses PyTecplot to change each of the three angles by 5 degrees and manifests the result after each step. 1)  […]
