Salut Laurent,
PLusieurs choses dans la même capsule:
1. It was created in a version apparently older than mine [5346 April 2014]
So, some of the animation code does not work for example 2. It plays once
and stops. I found no way to "repeat indefinitely". You can repeat as many
times as you wish, how ? => delete some 't' in the input data, retype 't',
it will repeat the single complete cycle.
2. I noticed that if you want to get the graph of the 2nd example, it is
wise to have Smath not open. Then reach were it downloads and click 'open'.
I noticed this behaviour with other work sheets not created in Smath 5346.
3. If you delete the if/else and conserve augment(col(el(K,tt),3),col(el(K,tt),2))
you can have each individual "Frame" by setting tt => 6..30 and export each
individual "Frame" solution.
4. The first example works well as viewed in the forum animated demo.
5. Draghilev module looks a complicated version of some discrete Runge-Kutta,
4th order. I don't understand what Jacobi is doing in there ... just
checking convergence the hard way ?
6. I know nothing about your "brick/cement" wall but I'm familiar with the
maths of the arc length. Simple if the function can be expressed in
analytical function or if not in discrete mode.
7. Close your Smath, follow step [2]. If it does not work, the problem
is with your actual more recent version than 5346.
