Hi, I have 2 files with data which contains x and y components of velocity field, I try to combine this data into vector and then create particle tracer, but it doesn't work. Here is the pipeline of the visualisation: 1. data is in NetCDFReader1 and NetCDFReader2. 2. appending: NetCDFReader1, NetCDFReader2 => AppendAttributes1 3. build a vector: AppendAttributes1 => Calculator1 (with the formula x*iHat + y*jHat + 0*kHat) 4. create seeds source for particle tracer: Line1 5. create tracer: Calculator1, Line1 => ParticleTracer1 6. animating.
but nothing is happening, ParticleTracer1 doesn't display any data, I tried to replace step 5. with ParticlePath or StreakLine and animate termination time, but it doesn't work as well. Note, if I use stream lines in step 5 they are working. Any advice what may be the reason? Or maybe you know any tutorial for particle tracing with real example (data, step-by-step instruction). Thank you, Mike
