Mass Balance Solution with MATLAB

[@apm]

The lecture notes and source files are now available at github.com/APMonitor/applications/tree/master/transient_balances in MATLAB and Excel.

hello professor can i know the question is located? it is because i just found out the coding of the matlab on your website.

Ciao! Professor, I always get this problem whenever I try to solve. Using default imode of 3 (steady-state optimization) Reference to non-existent field 'time'. Error in Example1 (line 9) time = z.time; Please guide. Thank you!

[@apm]

+Asad Imran, we recently changed how the solution is reported. Please replace z.time with z.x.time. Let me know if that doesn't work.

[@asadimran6707]

The problem still persists. The problem appears like this now: Using default imode of 3 (steady-state optimization) Reference to non-existent field 'x'. Error in Example1 (line 9) time = z.x.time;

Could you subscribe to the APMonitor Google group and post your files? It is difficult for me to pick out what may be wrong from this information. I'll likely need the files that you are trying to run. You should be able to see the solution when you retrieve it with: y = apm_sol(s,a) disp(y) z = y.x disp(z) It should also create a new data file (csv) in your directory that has the solution.

Thank you Professor. I just uploaded the file in the Google Group.

I don't see it yet. Here is the link to the group: apmonitor.com/wiki/index.php/Main/UsersGroup in case you got the wrong one.

Thanks for this great video. Can you please point out the source of the questions, primarily question 1 with the storage tank

hi..professor. I have stupid question is why we have to add opm file then we run matlab file..so what is the feature of omp file. thanks....

[@apm]

This is a good question. The APMonitor Modeling Langauge (APM) is an add-on to MATLAB to help with simulation of dynamic systems (differential equation solutions). More information on APMonitor is on Wikipedia (en.wikipedia.org/wiki/APMonitor) or from these tutorials: apmonitor.com/che263/index.php/Main/MatlabDynamicSim You could also use an integrator such as ode23 or ode15s (in MATLAB).

Thanks APMonitor.com, can you share me your project example_1, i only use for my research. I am a PHD so i want to know about mass balance solution.

[@phamduc-hung565]

thanks so much sir.
