Has anyone had any experience with "Engineering Equation Solver"?

 

=============

I could use MATHCAD or MATLAB but I might as well use excel if I am going to use one of those. I have used EES for a couple of years now and the true power in it is being able to simultaneously solve systems of equations. For example, I could input 5 equations with 5 unknowns and it would solve for all 5 unknowns instantly without any manipulation to any of the equations. It could even simultaneously solve 100 equations with 100 unknowns!! I could pretty much input them as how they were written in a textbook or scientific paper without manipulation. If I was to do that in MATLAB, MATHCAD, or Excel, I would need to then waste a lot of time setting up a matrix to solve and you could imagine how time consuming that would be with 10+ equations/unknowns. EES is able to determine the variables that are unknown and its architecture automatically organizes the matrix and solves it. EES is also very powerful at combining this feature with being able to parametrically sweep design variables.

Units incorrect? lbm, lbf

July 22, 2005, 12:00 am

MathCad (2001i Pro) defines lbf (pound force) as 32.174 mass * length / time**2. Since we all recognize this as acceleration due to gravity we know the units are lbm, ft, and seconds squared. But the textbook definition of lbf is the above divided by the "gravitational constant" also 32.174 but the units include lbf in the denominator. This is critical; it shows that on earth, lbf and lbm are equivalent. But MathCad doesn't see it that way and it has been playing havoc with some gas calculations I'm doing. Any comments?

Excel to Mathcad and Mathcad to Excel data transfer

Dear all,

 

I got thanks a discussion chain some Mathcad macro's to read data in any worksheet in an excel file but thw woksheet name has to be known.

My data acquisition system generates automatically excel data table with every time new worksheet names.

Is it possible to obtain all the worksheet names of an excel file directly from Mathcad ?

 

Second question:

It is possible to read directly from Mathcad data within worksheet of Excel file and it works well.

Is it possible to do the reverse, ie to write data direclty from Mathcad in specific worksheets of an excel file ?

 

I have Mathcad 14 (will have mathcad 15 next year)

 

Thank you

Hi, We are running Mathcad using a license server. Unfortunately the server stopped working a couple of days ago. When trying to start the ptc_d daemon, the logfile shows 22:06:22 (lmgrd) ptc_d exited with status 25 (Invalid host) The hostname did not change, nor did the NIC. Any clues on what might be the problem?

I upgraded my workstation and have done all wich have been available, but still no go.

"Unable to create 12.0 engine factory" is only indicator of the problem before 14 start-up logo vanishes.

Mathcad 15 - Preferred units in results?

I am using Mathcad 15 for a course in Quantum Chemistry. Is there a way to set default units so that they match those commonly accepted in the dicipline?

 

For instance, when I calculate wavenumber, my result is in m^-1 rather than the commonly accepted cm^-1, and frequency is in s^-1 rather than Hz.

 

Thanks.

 

Best Regads,

Matthew

This variable is undefined error when using Given/Find function, why?

Hi Everyone,

 

I have been using mathcad for some time but it is not until recently i started trying the Given / Find functions.

However, every time i try it, it gives me "This variable is undefined" error right after i enter the Find(...) command and hit the "=" button.

I even tried to follow the quick sheet in the tutorial/help document and it is still happening.

 

Could someone help me out?

 

Greatly apprecitated!

Radian to degrees

I am new to using MathCad, but it seems that I should be able to figure out how to change from radians to degrees. The manual is pretty much worthless, and the help section merely states that MathCad gives results of trig functions in radian mode. No kidding. Any help is appreciated, and yes I feel like a moron.

Hii there

I have done mathcad programming, in which I learn in the hard way, =taking
examples from the tutorial, it is much clearer if you be able to open =the
attached mathcad sheet. I having problem to extract the result from the
iteration loop that gives the value twc.

The final value that I am interested is twc under the heading ITERATIONS =TO
FIND REQUIRED WALL THICKNESS FOR STABILITY in which the value is =obtained
from iterating the of all the parameters above and satisfying the =condition.
However I need to get the result for the other parameter such as B, FW, =UD
and others that correspond with the final twc. Could you advise me how =to get
about on this.

For your information I am using mathcad 11

Appreciate your help and advise.

Many thanks <<mody.mcd>>

Mathcad 6.0 + and Windows 7

Any Mathcad 6.0+ fans out there?

 

I've been using it since 1995.  I got the Mathcad 7 and 8 upgrades and hated them.  So, I've been using 6.0+ ever since. 

 

Mathcad 6.0+ ran fine on Win 95, Win NT, Win 98, Win 2000, and Win XP.  Win 2000 and XP were a little trickier to install. I just took a good install from a Win 95 machine, copied the whole WINMAD directory and transferred it to the 2000 or XP machine. Then I tweaked the Windows file associations manually. 

 

Now I have Windows 7.  I tried the same procedure.  Most everything works fine, except when I Save or Save As...  Mathcad 6.0+ shuts down abruptly.  I’ve fiddled with the Compatibility mode and settings, but I get the same results.

 

Any suggestions?
