So are we trying to calculate h as time passes?

The heat transfer coefficient is the heat flow over the surface area and temp difference of object with the air.  It sounds like you want h as some function of the outside surface temperature of your object as I think Preben has asked?

Whenever I type in ⊥ it gets converted to the graphic in the line but then shown as ⊥ in the graph.  Not sure how to stop it from converting while I type. 

Executing your worksheet shows ⊥ in the graph instead of the graphic however this is probably Maple12 specific.

An extension to the general idea of the above would be how to access worksheets across parallel kernels

After modifying the file to run in compatability mode we just needed to add the ctl3d.dll file (not sure why it wasn't there) was in my other XP. 

MapleVr3 saved files as .ms

I guess MapleVr5 version saved them as .mws

I agree, the backward compatability is actually really good. 

There are in some cases where an application won't fully display itself on newer maple versions....

Hold on one second!  I just realized and tried the application in Classic Maple 12 which works fine (don't know why I didn't think of that earlier).  It just doesn't  display so well in the GUI.  I suppose if you were a user of the Classic interface you wouldn't notice it.  I use the standard GUI all the time.

And the reason for installing such an old version on a new PC?  Well, the problems just kept mounting up.
First the application didn't work in Maple12 GUI so I thought I needed to install and older version to view it properly.  Then I ran into the divide by zero overflow error, so then find an older computer where I had already installed my MapleVr3 and found out it was actually a MapleVr5 application which wouldn't run on my MapleVr3 then I started searching for an old newer version of Maple that might run the MapleVr5 app.  Didn't have Maple6 but did have Maple7 which of course worked.  Then as you can see, I just found out it would have worked perfectly fine in the Classic version. 

Now it's just for the fun of trying to get MapleVr3 to work on a new PC - it should but it doesn't start so how do we do it?  Maybe messing around with the maple.ini file might help it load properly, not really sure.  Then just now I'm even pondering wether I could get the old version to work on my smartphone.  Now that would be a challenge!

Anyways I'd like to clear / fix up the divide by zero error if we could.

Without access to Maple I cannot access and marvel over peoples work in the application center on my smartphone.

View html version still does not work.

Not sure if Maplesoft has picked up on this issue yet.  I will submit a software change request, the issue may have been missed. 

Ironically I just found that problem yesterday but I thought it was a problem on my end and I was going to take a look at it later today.  See if it was on my end or a site problem.  Looks like the latter.

The initial search pass returns nothing there is a bug somewhere there. Further Search clicks also return nothing. 

However ...

Clicking on advanced search after it has searched brings up 5 pages of applications with polynom root and clicking further to versions prior to Maple 10 we get another 9 pages of applications with polynom root.

I saw something similar to this last year.  But I thought it was related to my out-dated Internet Explorer.  I didn't bring the issue up again when I switched to firefox for fear that more tinkering in the application center by programmers might break it (vaguely recalling the data loss, but then found again, when mapleprimes switched over to version 2)

Pardon my lack of understanding, but why would you need to convert *.mw files to *.mws ?

I cannot view the html version of any application in the application center.  Since it is not fixed and I still experience the problem, it must be that no one else experiences this problem.  This is on Firefox, and my mobile phone Android.

Usually when I report a problem here in mapleprimes, it gets picked up by maplesoft.  I posted the issue last Friday, again it is Friday and doesn't appear anyone picked up the problem.  So I think I should update this thread on Monday for someone at Maplesoft to take a look at the issue then.

@ Junlin Xu, you may have a point about System Modeller not fully integrated with Mathematica. 

However had you fully understood the functionality of Mathematica's system modeller you would have known that, and I quote
"... SystemModeler integrates directly with Mathematica—bringing in our whole 25-year Mathematica technology stack." from Stephen Wolfram himself. 

Also remember to keep your thoughts of other peoples understanding to yourself, thank you.
