@sand15 Sir, it's not a disrespectful attitude. We are here to seek help from experts like you. Actually, you spent a lot of time, but the problem is that I do not see my original system of ODEs in the code. Even when I run the file you uploaded, it totally changes the view of the graphs. I wonder why it is happening to me.

@sand15 Thanks, sir, for your suggestion. I really do not want to waste your time. I tried another approach, and the results are reproduced, but the view is not good. I tried a lot, but I cannot enhance orientation and fix the legends issue. If possible, take a look and help in refining graphs. For reference, see the attached picture.

@sand15 All information is available in my Maple worksheet. I am not getting an idea of how to get this information. I have only the values of all parameters, which are already given in the worksheet. I am just trying to change my line graph to a bar graph view or a 3D surface plot

@sand15 How to implement it for my problem, not in general? I have uploaded my worksheet for line plot. kindly help

@sand15 sir thanks for your suggestion. I am looking for almost similar style. The picture I uploaded as a reference have retangle style of bar graph, but how to implement in my case?

@janhardo sir thanks alot your support 

@janhardo sir, can you please help me to fix this issue? I think the problem is in this part. 

#-------------------------compute nusselt num ate y=1--------------------#######
                     

      Nu_results[i, j] := eval(-diff(theta(y), y), dsol(1));
end do;

This diff(theta(y), y), dsol(1))  is not working properly. Besides this, if put 0 at place of 1, the same file works good and give different values for Nuesselt numbers.

@janhardo I changed some values and functions in the previous code that you uploaded, but after this it did not provide any values. I followed all of the steps you wrote. Can you please help me correct the file?

@janhardo  Ok sir, thanks a lot for your help. My last query: I am calculating the Nusselt number, but it gives the same values for all parameter sets. Can you please help me why the code is giving the same results for the Nusselt number?

@janhardo Sir, does the file work on your computer? Because it gives error in my side

• @janhardo Sir, thanks for your help. Is it possible to generate single values of skin friction rather at any point of y=0.1 and k=0.1, other parameters remaining the same, then tables or an Excel sheet? 

@janhardo sir, attention is to view nuemric values in tabular form at one point of y such as 0.1 for each k=0.1,0.3,0.5,0.7,0.9 and also looking for to generate 1001 data points of skin friction in the range of y=-1...1 for each k values.

@janhardo Thanks, sir, for your help, but in my system, there is an error.

@janhardo, Thank you, sir; it's working perfectly. I had also submitted another question regarding how to export data points of a different quantity (from the same system) to an Excel sheet. However, it seems that my question was deleted by the system, possibly because it was marked as a duplicate.

I need further assistance on how to generate tables for the skin friction parameter and correctly save the data points of another quantity into Excel. Although the line graphs are generating correctly, there is an error when exporting the data to Excel. Also, in addition to line graphs, is it possible to create 3D graphs for this quantity? Please have a look at my Maple worksheet.

@janhardo Good day, sir, and thank you very much for your help. In the first part of the file, the tables and graphs of the Nusselt number might have been skipped by you, and they were also showing errors in my file, which I uploaded. If you don't mind, could you please help me with that as well?
