I have a similar problem if someone can add to the discussion still.
I have a graph of values over a range of a variable and I graph a constant alongside the function. My problem is that where the two functions intersect is *not* the correct answer. The graph shows a different value of intersection from that when it is calculated in MathCAD (I also checked the calculation outside of MathCAD to be sure).
I've tried dividing the units of both axes and that didn't work. I can't figure out how to change the line graph to a point graph as someone else suggested. Can someone tell me why the graph is obviously wrong?
The example problem does not have a jump discontinuity, both are smooth functions that are defined over the range.
PS I'm sorry, but I can't post an example file as my work has me under an NDA so I can't share my work with anyone.
Too bad you can't attach your worksheet or at least a picture showing the problem. Without seeing what you are doing its hard to advice.
You should try to recreate the problem in a simplified dummy sheet which does not contain any sensible, confident data.
Also you might get a better response if you open a new thread with your question.
Its also important to know which flavor of the program you are using, Prime or real Mathcad.
I appreciate the response. I will work on making a dummy file.
I can't start my own thread as I am using the trial version so I don't have technical support. I'm looking into opensource alternatives that I can donate to with my own money (my work doesn't want to pay for a subscription just for me). I have a lot of problem solving ahead me as I am taking it on to learn the new program and play around with MathCAD while I have the free access.
Are you sure that you can't open a new thread in this forum? I thought the forum is free to post for anyone. Just click at "Start a topic" on the right side of the large green bar and chose any label. It doesn't matter which one as nobody cares - just be sure to post in the Mathcad area.
While its not open source you might have a look at SMath Studio which is kind of a free Mathcad clone. It does not have the full power of Mathcad in some respects (symbolic calculations, plots) but is ahead of Mathcad in others (e.g. possibility to add features like better plotting via Add-ons). SMath Studio is the only alternative to Mathcad that I know of when it comes to the scratchpad approach where you can write live working math expression at any position similar to what you would do by hand, too. Like Mathcad, Smath is also unit-aware.
I tried to figure out how to post to the forums but the option is greyed out for me and when I follow the breadcrumbs to the PTC community it seems that posting to the forum is part of their "support" package. My patience is wearing thin with PTC and I've been problem solving with SMath. It's pretty close to the MathCAD 15 release and there are problems but it is free so I'll probably dedicate my time to it right now as I am making progress rewriting my old MathCAD code in that environment. I appreciate the response but it doesn't look like PTC wants freeloaders like me.
To me it looks like PTC doesn't want Mathcad-users in general (otherwise Prime would be quite differently) but to be fair one also has to mention that they give away a limited version of Prime for free. The trial of Prime falls back in the so called "Express" mode where a lot of features are considered "premium" and are not available. Nonetheless some people might find that the basic features left are all they need.
But I am really surprised to hear that you are not allowed to open a new thread here in the forum.
@Jaime_Lee can you confirm that only users with a standing maintainance/support for a PTC product are allowed to open a new thread?
@Werner_E is correct. Maintenance agreement or no maintenance agreement, we definitely want you to share your questions and insights on this discussion forum. I tested your account, and I was able to start a new thread. In the Mathcad Ideas area of the community you do have to have a license agreement, but you can vote on other community member's ideas. Great catch on the labels @Werner_E ! We do care about labels, but we haven't been doing a good job "cleaning" them up when content is moved into the Mathcad area. We will work on this!
So yes, I can now figure out how to navigate the site to post a new discussion. But now it is not needed because I can't recreate the error I was running into when I tried to make a dummy sheet to display the problem. Somehow, I imagine it had to do with units somewhere along the way.
I really like PTC 6.0 but I'm afraid I will run into problems whether I run with PTC 6.0 or an open source tool like SMath and I might as well save my very low income and invest in improving my problem solving skills instead of investing in such an expensive (and I'll admit, powerful) tool. It just doesn't make sense for me at this point in my career. I'm kicking around the idea of having someone help me pay for it but as of now the cost is the main factor in not being 100% on board with it.
Again, thanks to the community for helping the noobs navigate the support.
Don't give up!
When Prime runs without a license (like after the 30 day free trial,) you have Prime Express.
Express can do two things:
What's "left" is a Mathcad that functions nearly as well as version 7 did but it's FREE! And people have been finding "work-arounds" for some things that we might still need. (There's a grid-drawing program that will give you a grid (including log plots) in the original Prime plots (cntrl-2).
Express is worth keeping even if just to read other contributor's files; but it can do some fairly interesting stuff itself--you just need to be innovative!
Sample attached, created in Prime 4.0 Express.
Thanks for the clarification, @Jaime_Lee .
BTW, as far as I am aware nobody can vote for ideas in the Mathcad section since the forum migration. I don't think that's intentional but IMHO its not a big loss anyway 😉
