Hello,

I have a little question concerning the definition of the rotation matrix in the rigid body frame.

The rotation matrix is defined like that in the help menu : "The rotation matrix that transforms a vector expressed in the outboard frame to the inboard frame".

Consequently, we have :

Hello,

I would like to define my model with symbolic parameters. Consequently, i have to define the symbolic parameters and theirs values in main folder.

To illustrate, i define my parameters a1, a2 like this.

After, i need to define a frame by using the parameter a1. This frame is define like this :

Hello,

In multibodies system, there exists many kind of coordinates namely joint (or relative) coordinates and absolute coordinates. Moreover, for the joint (or relative) coordinates, it is possible to choose strict, simplified, or complete coordinates.

For the moment, i only find in the tutorials system modeled with complete joint (or relative) coordinates. I will give the example of a 4 bars mechanism. The kinematic scheme with this complete joint coordinates is the following :

Hello,

I often need to present my results.

How i find that the maple sheets aren't very useful to do this. I use of course sections to keep my page of results clearer but when you have many lines, it is very nice to my mpoint of view.

I recently discover the "slideshow" mode. I could be interested but i have some troubles with this mode.

First, as i use sections, in the slideshow mode, i see one page per section. But when i have many lines in...

Hello,

To simplify and try to keep my program structured, i use sections. I often need to desactive all the lines codes of a section. Is there a soluion to desactive many lines in the same time without putting this # to each line.

Thank you for your help.
