I dont know anything more than you about the ratio field, but I seem to
remember a post by John Swanson sometime back where he gave a relation for
determining the ratio. I think it was based on some function of the number
of points. Perhaps you can find that post in the archives.

Hello:

I have been playing recently with the *MOPER command to do some CFD mapping
on a thermal model. It works really great. The only point I don't fully
understand is the argument "Ratio" which is used to limit the search for
the
nearest points. I changed its value with no much effect, so I was wondering
how it works exactly.

The help says the following: Relative pinball search radius (pinball size
to
total size based on min and max coordinates contained in Par2). Defaults to
0.1. This argument is used to limit the search for the nearest points.

Is that distance related to the distance of the exterior nodes to the
surface (i.e. the distance perpendicular to the surface) or is it the
actual
distance of the exterior nodes to the different nodes at the surface.

Also, if the model is quite big (which is often the case), isn't 10% of the
model rather big? Even with the default equal to .1, the *MOPER sets the
results to zero if Kout=1, which means that it is not able to find a
corresponding nodes with a large search radius.

Thanks in advance for any suggestion.
