Mathcad 12
Mathcad 12
(OP)
As some of you may be aware, version 12 has been released; has anyone upgraded yet and if so, is it worth it?
More importantly, has the activation issue been dropped? There was a lot of talk earlier on this board about this problem.

v12 just ended its beta-testing last week, so the software is not yet released.

Did you participate in the beta? I couldn't find anything about it in the Collabratory, I'd like to hear from someone who was in on the test - is it worth the upgrade cost? I've really felt ripped off by a couple of the "new" releases in the last few years and was thinking about not going to 12.

Sadly, I don't think there is anything that comes close to Mathcad. Any ideas or do I have to break out the spreadsheet?

You could check out TK Solver 5. . The standalone version only requires a serial number intsall. The new report writer works great. www.uts.com
RE: Mathcad 12
There are some people, by choice or by force, still using much earlier versions such as 6, 7 and 8.
And if there were no CDilla, what would be the objection to activating your software?

At least with a dongle I can have two laptops. One in the office and to use in "safe" areas, one for use in the field and that I can afford to drop, have fried by stray nasties in a substation environment, etc but only one licence for Mathcad.

C-Dilla, as we all know, is a copy protection measure but as it installs without the users knowledge is classified as spyware http://www.privacyandspying.com/privacy-c_dilla.ht...
I am also against activation on principle.
RE: Mathcad 12
I am using v12. See http://www.mathcad.com/upgrade_center.asp for a list of the new features. First, I like the fact that its built upon a .net framework for stability and extensibility. The XML, metadata and user defined units are real time savers. You can save files with results because of XML. How many times have you opened a worksheet to wait for results that take forever to calculate? Metadata and the XML format make things easier to find. I usually have to open older worksheets one at a time to find the one I'm looking for. With these new features, explorer searches get much easier. Also, an oft desired feature - secondary y-axis on 2D graph. If any or these sound like something you need, then upgrade. Personally, I think that even the average user should find this upgrade worth the price. I have to admit that some of the previous ones were less than satifactory, but I think this one a winner.

Reinstalling your system might not be so bad if it were possible to ghost your hard drive and reinstall but the protections on Mathcad 11 are so severe that you cannot even ghost back to the same hard drive with the same serial number. That part is ridiculous. After this happened a few times I was accused by one of their tech support people of piracy. That made me furious. I am worried that if I ever install a new motherboard they may refuse to give me an additional authorization code. The other big problem with that is if you are working on a weekend and this happens (which it did once) you may miss a deadline.
There is one possible improvement that might cause me to upgrade to Mathcad 12 and that would be an improvement in accuracy of calculations done using the US system of units. For example on a project I am currently working I did the following calculation. (Rational Method for Stormwater runoff.)
CsubF = 0.69
i = 1.33 in/hr
A = 4.6 acres
CsubO = 0.10
t = 1.5 hours
if you calculate CsubF*i*A*t - CsubO*i*A*t defining the variables using units you get an answer that is 0.8% higher than if you just use the numerical values. The result when done on a handheld calculator is the same as the result if you do not define units. 0.8% may not seem like much but in this case it would result an extra 45 feet of 24 inch diameter N-12 perf pipe and filter fabric. This represents $1,063.00 more for pipe and filter fabric not to mention extra volume of gravel and the cost of additional excavation.
If someone who has Mathcad 12 would try this calc I would appreciate it. If they have corrected the inaccuracies (which by the way are discussed in a couple of places on their web site) I would really like to know if this problem has been fixed.
Thanks,

If you make the operation on HP48GX the result is 556.552315012_m^3 and the result on MathCAD v11 is 556.550088806035_m^3 which is 0.0003999994% for me is nothing!
