Hello Everyone,

I am working on parametric analysis using Workbench 15.0, please refer to the image attached. I have been manually varying the design point values and running the simulation for each row, I have to run many more cases and as you can see I have already run around 1540 cases. I wanted to know if there is a way to automate this process, i,e., run a loop of values for x, y, z, radius, and heat generation in Matlab and ask workbench to duplicate design points for each value in the loop and run the simulation for the corresponding design point. This way I can try many permutations and combinations faster than manually updating each design point.
I know how to start ansys solver in aaS mode and I have the AnsysAAS MATLAB toolbox installed and have some basic idea of how to run MATLAB-FLUENT co-simulation in MATLAB script, but I do not have any idea on how to run parametric analysis on Workbench through MATLAB.
The requirement is; given a set of values of x, y, z, r, and heat generation I want the temperature distribution over the model (which is designed), is there any other way in which I can do this, for ex: run a loop in fluent using Scheme programming.

Thank you.

Hi Shailesh,

have you tried using excel for your data points and connecting your excel to Ansys?
You can always code in Excel to run different points and in return ask Ansys to run the given code.

There is excel tutorial available in help section, go thru it and check if you can use it.

Hi Sir,

Thank you for your reply. We are working on image processing and machine learning also to solve our problem, the general flow being: i) image processing (in matlab/python (preferable)) ii) Ansys workbench for simulation iii) machine learning (in matlab/python (preferable)). In this flow, I get x,y,z,r from step (i-image processing) which defines the design point for my workbench simulation. I would like to:

i) call workbench from Python,
ii) define x,y,z,r,heat generation in python,
iii) automate the process in workbench to give the temperature distribution.

Right now I am manually feeding in x,y,z,r and heat generation to workbench and then manually exporting the temperature file to Python for step (iii- machine learning). I am sorry my original post was not clear on the details. Could you please help me out with this.

Thank You.

Hi,
the most powerful proceed is to use your own scripts, as you can see here, which includes also a Bibliography of useful sites:

Have a nice day!

Thank you very much for sharing this documentation, this is exactly what I was looking for.
This will come in very handy, thank you and have a great day ahead
