Hi,

I am trying to convert from MapleSim to Simulink Matlab by using the S-function code Generation connector, but I got the above message when I uploaded the selected subsystem and I have no idea how can I fix it. Please help me

To observe the nip impact of the Variable Nip Roller, we created the following schematic and simulation. I set the y-coordinate of the Web to be the same, so I don't think there is a big problem for the Variable Nip Roller to simulate the nip. However, the simulation does not simulate with the warning "Nip is not on the contact arc". What is the reason for this and how can I set the nip arc again?

This is a Tension Zone, an example of web handling.

The example probe on Roller1 shows various probe items, such as summary_WrapAngle and summary_Slipvelocity, but the ex_probe I attached to the same roller shows only four probe items: angle, angular velocity, angular acceleration, and torque. Why are the items different even though they are probes on the same roller?

I want to know the change of the web during the web handling process, so I attached the probe, and it shows the checkboxes to observe the velocity and tension values as shown in the picture, but there are 3 additional checkboxes like Force - T2 / real - e / real - e2, what does this mean?

How can a variable roller ensure that the nip is within the arc of contact between the web and the roller? Every time I run the simulation, it keeps failing.

Can MapleSim simulate a situation where a cable passes through a hole in an object, where the cable is constrained by the hole and the object also experiences forces from the cable because of the hole?

I was wondering whether the rendering of bars

looks also dot like on other computers

Looks like Newtonian notation

Modal Analysis is a very usefull feature. Only the animation window is sometimes too tiny.

How to enlarge this view and to pause the animation?

This seems to be a Maple plot window (a "Rotate the view" cursor is visible and the animation can be rotated). Are there any short cuts or functions keys to toggle plot view options?

Edit: Looks to my like a Maplet. Maybe a Maplet programmer can tell if that (what I am asking) is possible

Both, Maple and MapleSim in Versions from 2021 to 2023 do not start. A logfile is saved which starts as

# A fatal error has been detected by the Java Runtime Environment:

#

#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000000000000, pid=17256, tid=10520

# Problematic frame:

# C  0x0000000000000000

This only occurs when the notebook (on which the error occurs) is connected to the domain network. If the notebook is not connected, Maple and MapleSim can be started and will continue to run when the network is reconnected.

Has anybody seen this before or any ideas what this could be?

Edit: This all happened under Windows 10 on a notebook that has been running Maple for 3 years and only recently displayed this error.

Edit2: Connection via an USB doc which also connects to an external monitor.

I found this option in an API command ?MapleSim,LinkModel,Simulate:

    scalemethod : one of the following: "none", "minimum", "maximum", "geometric"
    Method of variable scaling applied to the system.

I did not find anything about scaling in Maples help system.

What exactly does the scaling do?

I found this option mentioned in help(MapleSim,Multibody,Dynamic_Exports).

For the example of the help page I tried

SliderCrank:-GetDynEQs(AugType = Reaction);
SliderCrank:-GetDynEQs(AugType = Lagrange);

but the output is the same (which I would expect since GetDynEQs is not defined with parameters).

In the help system I only find deprecated commands that use this option

How can this option be set in newer versions of MapleSim without using deprecated commands?

Sometimes the canvas in the 2d-workspace of a subsystem (or component) is grayed out and the parameters in the parameter pane cannot be changed.

Example from the Model Gallery where the mass cannot be changed

Another example of a CAD geometry where I would like to change color and transparency:  seeshell.msim

How to unprotect the parameters?

I have observed that copy and pasting (Edit2: in a new document) and deleting the original component and copy/paste back into the original document and reconnection of the pasted  component works. Are there shorter ways to unprotect? 

And: How to do the reverse action (i.e. protecting a component)?

(I could not find a "when" and "why" for the protection in the documentation. Maybe I overlooked something)

Edit:

Other reasons why to unprotect are suppressions of components and highlight of multibody ports and axes.

Adding or reformating automatically generated ports (Edit3).

I was not able to apply ICs (initial conditions) using the advanced parameter settings of the flexible beam component in the attached file. My intention is to have a beam moving at t=0s (velocity of end frame <> 0). The computed initial values for the elastic coordinates (see output console for the disabled component below encircled in red) indicate that the flexible beam has no kinetic energy at t=0s.

A workaround is to attach a rigid body to the end frame and apply the ICs to the body. (Inertia and mass of the rigid body can be set to zero.)

How to apply initial conditions to the disabled component so that it moves as the workaround?

Bonjour, petite question simple que je me pose la MapleSim permet de tout réaliser ?
