You can see in attach a solution one DAE (Simple Pendulum Motion) problem.
Without units - OK
With units - not OK
What is the problem?
Solved! Go to Solution.

All OK in Prime 3:
I can't see a good reason for your DAE to fail with units but work without units. I've attached an x-y version that does work with units, but it is formulated in ODE-only form, not DAE form (and if I change it to DAE form it fails with the same "incompatible units" error).

It seems to me that Prime can solve ODEs with units, but cannot solve DAE with units.
Jakov! Is it so?
PS
Allan, I will be in London (University of Greenwich) 8/30-7/9 and will be glad to present You my Mathcad-clock - http://communities.ptc.com/thread/32536
OK?

Great! But what are the dates exactly? Is that 30th Aug to 7th Sept. or what?
I guess these are the dates as the conference on water and steam properties is 1st to 5th Sept. I have a meeting in London on 4th Sept. Hopefully we can meet then.

Fine!
I have free time 4th Sept.
We can have a meeting if... I will get UK visa. It is very difficult...

Alan!
I am now in London. With Mathcad-clock
Hotel: De Vere Venues Devonport House, room 202
Address: King William Walk, Greenwich, London
We are looking into this... It should work.
