We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

What does the CFD-Post error: “Error reading number of domains (G/NZN)” mean, which is encountered when loading a .trn file?

  When the Transient Results Option in Output Control is set to Boundary Only or Selected Variables, the .trn files themselves won’t have the mesh data in them and as such can’t be loaded into CFD-Post on their own. A .res file or .def file which contains the mesh must be loaded in addition to the trn. file. When the Selected Variables option is used, the Include Mesh option can be turned on to force the .trn file to contain the mesh. When the options Standard, Essential, or Smallest are used, the .trn files contain the mesh and can be loaded on their own in CFD-Post.
