Hi,   I want to calculate a deflection of a beam with Odesolve in MC15.   The deflection consists of two parts: y1(x) and y2(x).   I could solve the y1(x), but when trying to solve y2(x), i got an error-message: "this variable is not defined" You can see it near the end of the sheet. The boundary-conditions are: deflection in the bearings are zero, the bending moments as well.   What am i doing wrong here? Thank you for your help.   ps.: The MC15 File can be uploaded only as a zipped file.

I got an error for "Given-Find" solve block(See attached file).Please, help me.M.S.

Hi all, I have forgotten the password for the locked areas of above and about 15 more files created about 6 years ago in Mathcad 13-14. I have attached the file in Mathcad 11 as suggested in some discussions. please help me find the password. Regards, Mukesh (-)

Hi Please help me to find the h value using operator and solve h. I got 4 answers . How can I select the absolute value from the answers.    

See attached pdf. X and Y axis both have the same scale / range 0 - 9350 When displayed in mathCAD Prime 4.0 only hte x axis is formatted 0- 9350   Why does printing / exporting change the plot axis??     Thanks Adam

You ask me, why does the PTC take away the good old Mathcad 15 and give us in return Mathcad Prime? You ask me, why does the PTC take away the good old Java Community and give us in return new Lithium Community? I will answer - it's all done because we have a lot grave sins.   Do you have another answer?

Hello! I have calculated the complete dynamics for a mass-point moving along a parabola curvation without any resistance like air-resistance, friction, etc.     The solution is correctly solved with the Lagrangesche-methos, the movement happens in that way i suggested. But sometimes it's very complex to create ODEs in that way and therefore it's better to use Newton's Laws.   I tryed to solve the problem with the dynamic balance of forces acting on the mass, but i couldn’t get the same solution in that way so i’m asking what’s wrong. (please see attachement including MP4 and Pdf-file)   Can somebody tell me what’s wrong there?   Thank you very much.

We have many computers with Mathcad 15 on them that the students use. The problem is that the software needs to be licensed through each user's account individually throught the Mathcad License Setup wizard, in which we configure it to use a FlexLM server and enter our server name with port 7788. This is very impractical when it comes to lab computers that hundreds of students use. I have seen that with other software there are environment variables for licensing that make the license universal for all users. I have tried things like LM_LICENSE_FILE or PTC_D_LICENSE_FILE with the value "7788@(our server)" but this doesn't work. Any ideas?

Hi I am having problems properly using the substitute function. Could someone show me where I am going wrong?          

I have a question.   I want calculate Gain and Phase. But I can not calculate Gain. Phase is OK. ??? I want to attach MATHCAD file. But I do not know how do I attach the file the message.   Please advise me.

Hi, I have just upgraded from 3.1 to 4.0. One of the features I was particularly interested in was the ability to save to a rich text format for easier integration in calculation reports. However - the maths and images all seem to have been exported in horribly low resolution which makes the feature useless to me. screenshot compared to this   I hope I'm missing some setting that solves this, because if this is really how the rich text export looks then it is simply unacceptable.

As of June 30, new release dates have appeared in the PTC's product release calendar (link is: http://support.ptc.com/cs/product_calendar/PTC_Product_Calendar.htm#RANGE!A608 😞 Mathcad 15 M050 - Q4 2017; Mathcad Prime 4.0 M010 - June 29, 2017 and is available for download (link is: https://support.ptc.com/appserver/auth/it/esd/product.jsp?prodFamily=MCD ).  

Hi, I've several emails. The one  used in mathcad is the oldest and I would like to change it with a new one.Is it possible? Greetings FM

Hi! I have been trying to convert a matlab function into mathcad 14. The function is attahced in matlab format.(lpsd.m) During this convertion i have found some difficulties with a native matlab functions. The BSXFUN. If you check that lpsg.m file you can see the bsxfun function inside a for cycle. Does anyone have any idea how can I solve this?   thanks for your time people! Cheers!

I am creating a document with multiple excel files embedded.  My fifth excel file is not showing the correct information when I exit excel and return to Mathcad.  Whenever I am in excel it seems to show the correct information but it is only when I exit does it revert back to a random tab.  Out of the five excels embedded, this is the only one doing this.  Has anyone seen this before and know how to fix it?   View from Mathcad with excel closed: View from Mathcad with excel open (this is what I want to show all the time):

Hi all, Can anyone tell me where is the small button to update the browser page? Or, maybe, it automatically updates, unlike the previous one in which there was the update button? Thank you

At the top level of (for example) mathcad there is no date and time information about the posts. All we get is this:     If we look at the post, the only information is "2 weeks ago":   We are a bunch of engineers and scientists, and could do with a little more precision than that. Is it possible to change it so that we see the actual date and time of the post, and preferably on the home screen?        

Why, can only upload video with MP3 or MP4 extension? Those with AVI extension are forbidden ....? In short ... Every good software should have a comprehensive guide or help....  it is not possible that when you encounter a problem you have to interrogate ..... the oracle .....

This is an introduction to the topic, not devoid of errors. Indeed, if someone, very kindly tell me, simply by writing the equation number, I will be very grateful to him.Thank you for your attention and kind regardsFranc

Given the geometry of the connector and the material properties, this worksheet demonstrates how to determine whether the force on the joint will cause buckling.You can modify this worksheet and adjust it to fit your own needs by entering:The connection yield strengthThe diameter of the baseThe diameter of the riserThe height of the riserThis worksheet includes step-by-step instruction on how to calculate for the force on the joint, the pressure on the joint, and the allowable pressure before buckling.  All formulas are included along with an example and solutio

i have a permanent license for MC Prime 3.0 and temporary one for 4.0 and both versions of prime are installed.  when i locate and apply the temporary 4.0 license to prime 4.0, my 3.0 installation also takes this temporary license.  when i apply my 3.0 license in 3.0, it modifies the license applied to 4.0 rendering it unlicensed.  can i apply different license files to side by side versions of Prime??

Dear All,I am new to both MathCAD and the problem in hand, so have some novice questions and also hoping for some general strategy and where-to-go-from-here guidance …I’ve derived an equation of motion for a mechanism, which is a 2nd order, non-linear ODE.  It’s an M-C-K type equation describing both angular and linear motion.  I’ve rewritten it with all angular terms re-defined as linear terms which has made it quite cumbersome.  I want to solve for displacement and time.I tried using Odesolve, but couldn’t make this work with the full ODE (smaller chunks tested the syntax as OK, but seems it can’t cope with the full equation).  I’ve now manually re-written it as a 1st order equation and use rkfixed which seems to work.It's probably not the most elegant/efficient approach so will appreciate any suggestions for improvement here.I stripped all units out while trying to make Odesolve work, and haven’t yet attempted to reinsert them, is doing so advisable with rkfixed?

Dear All,Has anyone encountered the error "The requested file is not a valid MathCAD XML worksheet" when trying to open a previously OK file?I've lost a couple of days work to this now over the last month so would appreciate any suggestions!My machine spec if relevant is:W7 enterprise, SP1, 64 bit with Intel X5680 CPU @ 3.33 GHzThanks in anticipation,Standish.

recently upgraded from Win7 to Win10.  Prime 2 installed and activated fine.  after opening a new sheet.  i get an error for any function i create.even in the expression "x:=5" gives the error "this variable is undefined..." see attached.maybe a setting somewhere??
