@Carl Love ah, thanks. 

Curiously how are you getting Maple to convert from MPa to psi without any conversion command and vice versa?


Ah, ok so this goes back, way back but the answer was exp(Pi)-Pi


In the GUI, it would be nice if you there was a quick shortcut to enter equations you've entered previously

perhaps pressing CTRL and the up arrow could cycle through all your previous entries? 

@Carl Love Even I forgot about killing the kernel.  I think he may have found your answer to work for him and he's just forgotten to respond, he is a super long time user so he should be back. 

To clarify for the op (he's probably using windows) under the task manager he needs to end the mserver.exe processes.


Currently there is no option for drawing a non free hand partial circle, adding arc option or partial erase would work.  Currently the eraser tool erases the complete object.

Resizing the image also scales the drawing - it would be nice to have the option to change the frame size of the canvas while leaving the drawing scaled as drawn.

After leaving Maple 2021 open for a while without doing anything.  All of a sudden it's fast.

So it appears now maybe there's some processes going on causing Maple 2021 to be slow when it's initially started.  More looking into it tonight.

@Acer - fair enough

So this seems to be a Maple 2021 issue?  I will have to roll back to 2020, see if the issue disappears.  Does this happen with Maple 2022?

@tomleslie covid fog I guess.

@Anthrazit Sometimes I've found the highest resolution setting does not offer the best quality, sometimes stepping down one resolution setting gives better results.  This could be the reason why (as you mentioned above for a vertical screen) the resolution appears better.  Just a thought. 

I'm using a 15" laptop set at 1200 x 800 and Maple 2020 text appears good.

@Anthrazit Check windows performance settings and check the smooth edges of screen fonts.

Try also turning on cleartype in the control panel.  type in cleartype from the windows start button and make sure it's checked. 


1 - yes I meant the expressions palette

2 - the f can be changed easily.  You can tab through from a to b to f and just change f to f(x)

3 - No, I think that functionality is only available in Maple and not in MapleFlow.  Remember MapleFlow only borrows a few elements from Maple.

@Will_iii Not exactly sure what you mean.

X:='X'   clears the variable.

X= returns X as it should when nothing is assigned to it.  If you query any variable you haven't assigned in MapleFlow it will return itself as the value.  That is if b hasn't been used yet and you type b= then the return is b.

But also remember that the sheet still reads from top to bottom, left to right.  So if you're entering anything before your clearing assignment X:='X', then it will (as it should) return whatever that variable has been assigned by, on your canvas,

If I type in the search bar "sowpods" nothing comes up.  I know there are at least 2 posts using the word sowpods.  The fact that nothing comes up suggest the search is slightly broken.

It does not appear to happen in Maple 2020 on another system.

Does it occur 2022?  or in 2021.2?
