DYMOLA: opc server how to initialize using dsin.txt or a mat file using MATLAB

Question

I created an OPC server in DYMOLA, now I have this in DYMOSIM to click and initialize

using a ".MAT" file of a dsin.txt

Now I created a GUI file in MATLAB, and take input for variables and created a mat file

>>save FLUID_INITIALISE area volume density

Now I want to initialize this using MATLAB

I can do this

>>write(Initialize,1) //To initialize a previous data

I know can do this using dymola , SIMULATION > CONTINUE > IMPORT

BUT I WANT TO INITIALIZE IT USING MATLAB

normal MAT FILE LOOKS LIKE THIS

Aclass=['Atrajectory';'1.1        ';'           ';'binTrans   '];
data_1=[0,3600;100,100;50,50;5,5;100,100;90,90;10,10;10,10;10,10;10,10;10,10];
data_2=[];
dataInfo=[0     1     1     1     1     1     1     1     1     1     1     2     2;
         1     2     3     4     5     6     7     8     9    10    11     2     3;
         0     0     0     0     0     0     0     0     0     0     0     0     0;
        -1     0     0     0     0     0     0     0     0     0     0    -1    -1;];

save INITIALIZER Aclass data_1 data_2 dataInfo description name;

Please tell I will correct or in next post I will take care instead of just voting down — Rohit gupta, Nov 17 '20 at 19:01
My guess is that people are offended by the all-caps title. All caps implies yelling. Use conventional style for best reception. — Cris Luengo, Nov 17 '20 at 21:14
Thank You!! I have corrected it and will take care of it next time! — Rohit gupta, Nov 18 '20 at 21:36
Seems to be a bit unfortunate timing, but Dymola 2021x discontinued OPC support: https://www.3ds.com/fileadmin/PRODUCTS/CATIA/DYMOLA/PDF/Dymola-2021x-release-notes.pdf -> page 46, section 3.6.4 — Markus A., Dec 02 '20 at 07:21

To solve this issue what I did is,

I initialized dymola with default dsin.txt [which is created once you click simulate button]

then I write new values to them using this

write(area,20);
write(volume,30);

.. etc

Now

write(Run,1)
