I first noticed this problem when I half the time I tried to calculate my sheet, and I would notice mathcad would get "stuck" trying to multiply two matrices (one of the matrices is an inverse of another which mathcad had worked out prior). Once it gets stuck it wont ever finish and I cant stop the calculation without exiting mathcad entirely. This tended to happen about half the time I tried to calculate the sheet and the other half it would work fine, without spending hardly any time on that particular calculation.
Its even more disappointing to hear that they just ignored a technical committee's advice. I am all for updating software and integrating it with other packages, but as a small consultancy we tend not to link all the packages up as by the time we set-up a mathcad linked to a drawing model file and maybe linked to an analysis file we would have spent all our hrs and missed our deadline! Most of our work is designing prototypes for our clients so the value in setting up linked bits of software is not really there as we rarely reproduce the same engineering.
I first came across MathCAD when I worked at Airbus in the UK, I guess their (or similar sized companies) requirements are maybe what is driving how they develop mathcad and the ptc suite. Certainly the wider community of small engineering companies has no influence.
If I had to guess, it could be Matlab who pick up the slack. They already own Symbolic engine (MuPAD but that's not mentioned in _of_computer_algebra_systems), and also have the Simulink graphical environment, so with a little bit of tweaking they could easily auto generate the computational flow graphs and do the dependency management. (remembering that each mathcad region has an anchor, which is a paired I/O point, and the flow is in page reading order, so easy to link as if a simulink design)...
Before PTC bought MathSoft/Mathcad, it had a very large user base of 'consultant' level users who used mathcad at a higher level that would be expected in a typical drawing office (DO) type environment. This included a lot of professional engineers and scientist types who were pushing the leading edge of their applications in a local sense and needed to extend the maths that was in their text books to the new environment and scenarios.
I have quite a few Mech Engs, especially those that are in Stress and Thermal analysis, who do some quite powerful analyses via mathcad, and would like (and benefit from) the integration with Creo a lot sooner that 'the other crowds' who are at arms length to the rest of the PTC tool set.
Hi, I'm using the Mathcad Prime 4.0 free version. The programm was working perfectly fine, but now when I try to run the program it doesn't work anymore. The mathcad logo appears, but then it disappears again and a main window never shows up.
your hard drive is about to break. So I advise you to save everything and replace it with a new one, and after installing the operating system, purchase and install a good antivirus (The others, the free ones do not serve anything), then install mathcad.
