please help me on check my schmitt2.msim schmitt's trigger 

I use Maple & MapleSim 2016. I linked my MapleSim model to Maple worksheet and ran it in the Maple.
After that, I wanted to make the compiled one by using "GetCompiledProc" command in Maple.
I know that this command helps making compiled model with some user-specified parameters.
However, if I try to compile my MapleSim Model, error message appears and process stops.

Error message: (In GetCompiledProc) numeric exception: division by zero

Is there anyone how to avoid this error? I cannot find any solution for my problem.
For the security problem, I cannot upload my MapleSim model.

I appreciate any idea or tip you may have.
 

Is it possible to edit 3D work space directly in maplesim? How?

Can we add a static (fixed) cylinder around a piston (translating cylinder) in the 3D workspace?

Can we draw in maple drawing and add it to maplesim 3D space?

Thanks for these basic yet unclear to for the past many months.

I have an excel macro file (enable macro or save as macro and run) in which the colour of cells keep changing by a macro named macro2.

Can we achieve it in maple or maple sim?

Any one please suggest a way for me to try out.

I dragged into model space prismatic FixedFrame and RigidBody components and prismatic joint along y axis. I also set mass m = 1 kg. The manual says set K_S = K_S and K_K_d in inspector parameter setting. It did not work out. So i set values 12 and 0.1 for K_S and K_d. I sreated subsystem sub of rigidBody and followed the following instructions,

After this i wanted to modify the equations. I could not. The same equation is reassigned.

Parameter and variable rows - are as shown in manual, but a blank row not available for user's use. But how do i get the variable x(t) there and rename it?

Thanks for an example of this chapter with an application of its use., if available with anyone?

I have made a program to plot y(t) vs x(t). Can you please modify to plot y vs x data from an excel file.

Given x in A column and y in B column in 5 rows.

Example data: [[1,1],[2,4],[3,9],[4,16],[5,26]]

I followed the basic example RLS circuit first. It worked out well for R = 24 ohms, L = 160 mHand C = 200 microF. Signal is step input h = 1 and  t0 =  0.1 s. Simulation td = 0.5 s

When I extended it for DC motor, the output for torque (tou) and speed (w) not plotted for h = 1  t0 =  1s and simulation td = 5 s for the same parameters as above the output required (shown in manual) is not coming. Is it because default values shown were different? Then how do i change? I am enclosing the file for view and help.

Hello,

I have an industrial robot model and I need to define constraints for the revolute joints. For example, R2 joint is only allowed to move between -165 to 165 degrees. Could you please tell me how I can impose these constraints?

Thank you.

Hi, i don't know what happened but every time that I run the simulation appears this: 

invalid input: Multibody:-GetMultibodyData expects its 4th argument, lsProbes, to be of type list(list), but received registerMultibodyVariable

If anyone can solve this problem, I am going to be very grateful. Thanks

Dear All,

This is probably an easy issue to solve.

I have imported an .xls file using the 1D lookup table.

I need the signal to be executed for 4 seconds which is also how long my simulation duration is.

So I set the Ramp height and rise time to 4s. For some reason when I display the signal using a probe it gives me the constant value of the first row of my Excel sheet. I need help to solve this! I have provided some visuals below.

Thank you for your time!

Hi everybody, 

Neither of these questions is vital but answers will be greatly appreciated

-------------------------------------------------------------------------------------------------
Question 1 :
Is it possible to manage programatically the character fonts in a printf command ?
(for instance to print some piece of text in bold font ... without selecting it and clicking the bold B of the toolbar)

-------------------------------------------------------------------------------------------------
Question 2 :

In order to have a nice render, I use to create my own format for printf command. For instance, when I have to “printf” some text I usually compute its length L and my “printf” format constructor contains a command  like  MyFormat := cat(“%”, L, “a”)

Unfortunately the length(…) command seems to be sensitive to accented characters :
                                     For people not familiar with french, "dégénéré"  (note the acute accents) means "degenerate".
length(“dégénéré”) returns 12
length(“degenere”) returns 8
… which of course leads to a very inelegant render, which is all I wanted to avoid

Why does “length” behave this way ?
Is it possible to bypass this annoyance while ensuring “dégénéré” has length 8 ?



Thanks in advance

 

 

I have proposed a SE site for maple.

This will help to put maple on SE.

Please follow this site.

We have moved to the next phase Commitment. Come and join us.

Hello,

I know that it is possible to conduct the dynamics of multibody systems with MapleSim. But, is it possible to conduct only the kinematics ? Would it be possible to share a example where only the kinematics is conducted with MapleSim?

Thank you for your help.
