I am trying to use the Streamline module to display particle paths in a static 3D vector field. (Although I am not using this for a fluid dynamics application, the vector field which I have is analagous to a velocity field.)
I'm perplexed by the behavior of some of the streamlines, which terminate within the solution space for no apparent reason (at least none that is apparent to me). According to the description of the Streamline module, the streamlines start from specified posititions and times, and continue until the particles either exit from the field or reach a region of zero velocity. The streamlines I'm generating start at the correct locations and, in general, appear to follow paths which are consistent with the vector field. However, although every data point in my model has a non-zero velocity, some of the streamlines 'die' within the solution space (i.e., away from any boundary of the field) as though they've reached a region of zero velocity. Are there known bugs in the streamline routine, or are there any obvious issues I might be missing? Thanks, Joel Risner Bechtel Bettis, Inc.
