About fix spring couple



There are two groups.

group1 (0,0,10), group2 (0,0,6) are connected by a spring with constant =

fix 1 group1 spring couple group2 1 0 0 4 4

1. Is that right?

what does the documentation say? did you make a (simple) test and
checked whether it works as expected?

If group1, group2 were connected by a spring, then move group1 with a
constant velocity.

2. Could group2 be moved or not?

again, this mailing list is neither an input file approval service,
nor the oracle of delphi. make a simple test, best something that you
can verify with a pen and a piece of paper, and see if the simulation
behaves as expected. the fix spring will do what the documentation
says it does. whether this is what you want, is for you to find out.



I try several times, but I see it is not working like the doc.

I think I am wrong at somewhere but not sure.

Thanks for your suggestion. I will try again.
