Hi Mick,
I don't know about the modern Mathcad express version. But in the old ones new worksheets couldn't be created. It was allowed to change numbers in formulas but not possible to add new formulas or perhaps it was just saving that was blocked. That I have forgotten.
It is a pity that PTC bought Mathcad and changed the pricing to an annual fee and in some ways made a worse version. Hopefully they develop it to become as useful as Mathcad 15.
SMath Studio is only partly compatible with Mathcad worksheets: https://www.google.dk/search?source=hp&ei=KD0zXZunJoLHwQKDl4e4BQ&q=smath+mathcad+compatibility&oq=smath+compat&gs_l=psy-ab.3.0.0i22i30.1349.69864093..69866750...0.0..0.143.2023.12j8......0....1..gws-wiz.....0..0j0i131j0i10j0i13j0i13i30j0i13i10i30j33i160.NhDSyRMyC5E https://www.google.dk/search?source=hp&ei=KD0zXZunJoLHwQKDl4e4BQ&q=smath+mathcad+compatibility&oq=smath+compat&gs_l=psy-ab.3.0.0i22i30.1349.69864093..69866750...0.0..0.143.2023.12j8......0....1..gws-wiz.....0..0j0i131j0i10j0i13j0i13i30j0i13i10i30j33i160.NhDSyRMyC5E. Parts of the Mathcad worksheets may be missing when loaded into SMath Studio. But SMath Studio is very young compered to Mathcad with all it versions.

Ole,
I was checking it out and everything looked super until I realized the cost, wow $620 a year, is the express free version better than SMath for simple electrical network engineering or do they limit the capabilities too much in Express?
Apps have become so vast trying each one out can take days and days so it's better to ask like minded people prior to investing the time then finding out it does everything one needs except the final calc where one derives the reactance of the part then asks one to buy the retail version fro that function. I hate when that happens.

Hi Mick,
There is a Mathcad community where work sheets can be shared: https://community.ptc.com/t5/PTC-Mathcad/bd-p/PTCMathcad https://community.ptc.com/t5/PTC-Mathcad/bd-p/PTCMathcad. There are also libraries with worksheets for different engineering disciplines. But it is easy to build your own calculation sheets. What I find very good in Mathcad is that the units are calculated automatic. If the units don't match there is something wrong in the formula. This adds some extra error catch. Mathcad can also calculate with imperial units besides the SI units and it's even possible to create customized units.
I think Mathcad has become too expensive. For the annual license fee you can buy lots of physical calculators. Of course they're not as flexible as a Mathcad worksheet with its good overview. I still use the old Mathcad 15.0. It is locked to the computer but works without paying the annual fee of the modern versions. PTC that now owns Mathcad are quite expensive except if you make your living by using the software. Mathcad is very time saving when doing calculations and everything is documented if saving the worksheets.

Ole

Hi Ole,
Thank you, I was considering trying Mathcad or Cadabra or Axiom but now that you recommend it for sure!
I seem to recall the Mathematica I used to use of a friend a long time back who was a math professor required about a 500 dollar add on for impedance and reactance network modeling, does Mathcad require additional packages also?

Hi Mick,
I use Mathcad as calculator. It has become too expensive and missing the animation ability so looking for an alternative. SMath Studio looks like Mathcad and is free (https://en.wikipedia.org/wiki/SMath_Studio https://en.wikipedia.org/wiki/SMath_Studio). I like the animation function to simulate transmission line reflections and standing waves etc. It can also animate wave patterns like the force fields of the Rhythmodynamics theory. I actually haven't done those simulations much since discovering the Rhythmodynamics theory.
The formulas are written like done on paper. The program then calculates the formula and puts the result after the equal to sign.

Hi Ole,
I was looking around for my calculator for deriving pulse shaping
networks and filters to use for loudspeakers and seem to have misplaced
it in digital oblivion.
I am pretty sure you posted a circuit for same sometime back wherefore
placing an inductive load close to the amp so was wondering if you can
recommend a calculator.
A further complexity arises when adding a Zobel to the shaping inductor
as the impedance becomes much more complex due to additional peaking and
added IM distortion but that's another story and as we all know
electronic design is always a compromise.
Thanks,
Mick
