@acer 

subsop is what I was looking for.

Thank you!

@Preben Alsholm 

Thats a nice option in cases where the replaced name is not part of the integrant.

It does not work for the worksheet I have attached above (see update).

@ecterrab 

Thank you for taking the time. I will continue digging. I have just discovered the physics mini course which I think is a good template for other branches of sicence an engineering.

@ecterrab In the attached file I compared the new command with a case from classical mechanics to derive equations of motion from D'Alembert's principle. In this case I noticed a difference in sign of the output which has to be taken into account. Would it be possible to return optionally an expression

diff(diff(L,v),t)-diff(L,r)

(as in the attached) instead of an equation?

In any case LagrangeEquations makes life much easier. Great enhancement!👍👍

The AD/DA converters you suggested provide logic signals on the bit level. This level of detail is not required for off-the-shelf micro controllers, which I want to simulate.

The plant in my model provides real signals by using sensor components of the MapleSim library. So, in those cases I would look for  AD/DA converters that work in the signal “domain” (i.e. that discretizes a real signal).  

Looks like that there are no libraries that match my request but if there are any components that can be used in combination with MapelSim's discrete components I would be interested. AD/DA conversion is not what I am primarily looking for. I have no solution for FIR filters. A convolution component with user defined kernels would be a big step in that direction.

Thank you for indicating what is possible today.

By the way, I tried to discretize a real signal with the components you proposed but could establish a proper logic 8-bit connection with 2022.2

Update: With 2022.1 the connection works and the trigger ports a visible

@alex_b 

Thank you, that’s very helpful. I have not noticed PORT LOCATIONS and SUBSYSTEM AUTORESIZE and will have a try.

I found a shorter way of to replace functions of t by names for the above worksheet

subsindets(old_eq, function(identical(t)), f -> op(0, f))

A much shorter way from acer

@acer Thank you again!

I have overlooked this assignment.

Thank you!

I have tried to figure out what the “simpler steps to create and update subsystems” are. Creating was already simple. I could also not spot “clearer component labeling” in my models. An explanatory video (as the one for the Web Handling Library) would have been nice to appreciate the details.

What I discovered instead is a much improved port alignment of subsystems. Without updated documentation, I tested it on models where I abandoned port alignment to straighten connection lines (see suggestion 6). It worked great on 4 screwed up subsystems.

I hope I am not spoiling the show before the documentation is updated but this is good news worth communicating.

Thank you for that 👍👍

MapleSim 2022.2 improved substantially on (6). I could easily figure it out myself even without updated documentation, which is a sign of good usabilty.

Congratulations for this simple and elegant solution!

I have found a way to force the clipping on Windows 10. After a system restart:

• Launch Maple
• Create a new document and type in something
• In the system settings for the display change the font scaling to a larger percentage (I did 150% -> 250%)
• Close the document to force the clipped dialogue.

This is not the use case that occurred to me last time when I posted the question. But maybe it helps identifying the root cause.

Also: After working for a while without restart but using other applications as well, the clipping was not reproducible anymore. When changing the font scaling I got an additional system message (on a blue banner) asking if I want to keep the settings. Confirming with yes to keep the scaling seems to make the clipping disappear.

Difficult to tell without knowing the Maple input.

Perhaps I have found an explanation why solve does not return a solution in your case:

I assume that solve finds a first zero at x=0 and discards it since sin(0)/0 is undefined at this point... and discards all other solutions of sin(x)/x (instead of returning another solution as one could have expected from the help page). Here are some examples in line with this assumption

Since other computer algebra systems provide solutions without additional options, I can agree that Maple could be more user-friendly in this case.

So far, I managed to survieve with blindfolded Tab & Enter. The short cuts are much better.
Thank you!
