Thank you for your help.

I have my problems.

In fact, when you put directly numerical values, the 3D visualisation is automatically updated.

But, when you put symbolic parameters, the 3D visualisation needs to be updated thanks to a button on the 3D visualisation tools.

OK it's a idea.

An do you know i can export "slideshow" ?

Is it possible to export it in a pdf ? or powerpoint ?

Thank you for help.

Hello,

Can you precise me what is an execution group? May be there is something i don't understand ?

Is it un line beginning by [> ?

Do you mean that i can't to this (see below) to desactivated multiple lines ?

That's interesting.

However, i would like to have dynamic equations from the model expressed as a DAE because the choice of coordinates have been "absolute coordinates".

In fact, i would like to have in a symbolic form the DAE equations which are for the planar pendulum theses equations :

Similary to your method, I try to use commands for dynamics : GetDynEQs() or GetSysEQs(). But, with these commands, it seems that no option like with "GetFrameMotion" exist to ask to have the result with "absolute coordinates". So, i'm afraid that maybe it isn't so easy to obtain the dynamic equations with "absolute coordinates". It's a pity because many books dealing with "Multibody dynamics" used absolute coordinates in their formalism.

OK.

I have check the help section you told me but unfortunately, i found nothing about that.

msim_whitepaper.pdf

I don't find any model or comment on that subject (modeling system with absolute coordinates with maplesim) except this pdf.

In this pdf, they explain that MapleSim can deal with DAE which is very good and thet explain also that DAE can come very quickly. They give the example of a planar pendulum which gives DAE if it is modeled with "absolute coordinates".

So, it is very interesting and gives me hopes. However, i would like know how i can model a system with absolute coordinates ?

Thank your help.

It's good.

In fact, i should define the parameters before in main subsystem defauft settings and after i can use the parameters.

To complete my last question, in fact, in the section "Parameter and Variable Manipulation (optional)", i don't see for example the parameters of mass of the different bodies of the slidercrank mechanism

I still do not have an answer!!!

Thank you for your help.

OK. Thank you for your help.
But there is always a issue of values!!! 
The values with the different methods are still different.

Here the calculation
