I second that.
I built some models earlier this year but modeled deflections were
lower than testing by ~30% and I couldn't figure out why... so I lost
interest. It is possible that I needed to have separate nodes in the
rim for where the spoke attaches and the CG (I was modeling a 30mm
rim), instead of just having a single row of nodes around the rim...
that was the next thing I wanted to try anyway. Building models is a
very tedious job. I used the "Lisa" free program, which eventually
seemed to work well enough. I figured out the input format, then used
excel to build the input files.
In these kinds of tedious model building chores I always
write a program that creates the model. Use any language
that suits you: Perl, Python, shell script, C, awk, Fortran,
.... (but not Excel) It is always worth the effort.
