Thank you,

...but I rather thought about:

with(Units[Natural]:
Do(cos(%Slider*deg) inside Component properties ->"Action when value changes" field.
when slider vaule changes beetwen 0..90 deg

@pagan: Thank you once again!

But I'm not sure if you exacly understand what I mean.

In your code I must:
#1 - change slider position, #2 - execute worsheet to obtain value.

I'm wondering if it possible in Maple
#1. change the slider position and get a 'a' value on the same time.

...without additionall clicking.

Thank you,
 
I'm asking about possiblility to updating 'a' value during moving a Slider.
Slider represet 'q' value which I'd like to display on screan simultanoulsy. 

It is very easy in Mathcad

When I posted this problem I used Maple 14.
I don't know which version you have.. But Maple Support a few months ago promissed me that problem will be resolved in next (15) version of Maple.

...and they did it.




Best regards

Could anyone confirm, that is it a bug of Maple?

Original question was: What's happened when we rapidly change convection condition (for example heavy rain) for given material properties, IC and BC. On the beginning I assume that hconv=f(time), but Maple produce wrong results when h growing from 9 to 1000 W/m2K during few seconds. I tried another approach...
I needed steady state for T(0,x):=Tinit(x) (finally Tinit := (685-1573)*x/(.22)+1573), Tinit for given IC, BC and 9 W/m2K) and new IC1, BC1 (h=1000 W/m2K) for solution when heavy rain flow on the horizontal cylindrical surface.
I know that easier way exists, …but I had a model…
if I assume enough time period I reach thermal equilibrium… it was easiest for me in this case.


For me was big surprise than Maple produce wrong results for relatively simply problem. In the same time from MathCAD I got right results.

Hi, Thank you for replay!

...but I would prefer to check solution using different software, without fitting to know solution from another source.
