Hi, i am new to Mathcad. I am having difficulty recreating the model described in the attached study.
Since there are so many equations, it is getting very overwhelming.
Any tips on how to get started would be highly appreciated.
Mathcad and Prime has several file formats. Mathcad 15, Prime 3.0, Prime 4.0, and Prime 5.0.
Which one are you going to work with?
It's good that you picked something easy to start with.
Seriously, this will be a major undertaking! If you have a very good grasp on the science you might be able to do it. Someone with a good grasp on Mathcad could (probably) create the equations, but to do this right you really need both. There is such a person--Valery Ochkov, and he is a frequent contributor here.
The advantage of Mathcad will be that the equations will look a lot like what's published when you're done. That makes finding errors a lot easier (IMHO.)
You're going to need a good understanding of vectors and the way indexing works, and you need to understand functions as well.
It would be good (if you're committed) to make a start; create a Mathcad file and start entering equations. You'll get a lot more help if you post a document than a request. A lot of people will help correct mistakes and suggest methods; very few will post a file to a request.
Thank you ValeryOchkov for your response.
Yes, the author has used MathCad 2001i - that is why i believe i can re-create the model for myself.
I am using Mathcad 15.
Thank you Fred for your deep insights - they are already helping me.
My plan is to create the model described in section 2.1 which comprise of equations 1 to 16. This will allow me to check with the data shown in the paper to see if the model has been created correctly. That will then allow me to use the model meaningfully for further research.
Attached is the mathcad project file after i entered all the available data and some of the initial equations. I am finding it difficult to work with all the various subscripts and how the equations get deeper and deeper. From the tutorials on youtube and elsewhere, i haven't come across such complexity, it has mainly been defined parameters and then solving an equation for an unknown, while here i have to correctly link sets of data first and then i can solve.
I hope i can get your's and Valery Ochkov's support.
Now it is a good style to publish articles with calculation in form of Mathcad, Maple or Mathematica sheets!
Or/and as a minimum - authors give readers link where readers can download sheets.
The high style is to publish e-version of articles with online ( alive) calculations. Readers can change input data and see new answers.
In is my style!
