Hi,

I need to run Ansys from Matlab. I write the code

dos('ansys145 -b -i model2.txt -o output2.txt');

Then I get an error

ansys145 is not recognized as an internal or external command, operable program or batch file.

I try adding "C:\Program Files\ANSYS Inc\v145\ansys\bin\winx64\ANSYS145.exe" as a path to Environmental Variables but the problem is not solved.

Hi Prakul,

I will suggest to use interactive connection between Matlab and ANSYS (aka the ANSYS aaS connection). The link provided by Sarah is a very good start ( MATLAB Apps For ANSYS )

Using ANSYS aaS you will be able start Matlab and ANSYS on two different machines (e.g. Matlab on Windows and ANSYS on Linux) and connect them. You will be able then to issue one command(i.e. one line in your in.txt) at the time and retrieve the output/error for each command.

The approach that you mentioned will implicitly require ANSYS and Matlab running on the same machine, and further more ANSYS will most surely execute in the memory of the Matlab process, therefore it will be applicable only to relative small academic ANSYS simulations. The aaS approach will let you to execute large ANSYS simulation too, e.g. parallel simulations running on multiple compute node on a Linux cluster. On top of thatm with aaS, you do not have to wait for ANSYS simulation to complete and read the output file, but you will be updated by the simulation progress as this is executed.

Thank you for your response and guidance,It's so helpfull. But I have a problem , i want pop up fluent for one time and then run it by some journal file multiple time in the following of Previous one , i dont want to pop up fluent for every journal file separately, is there any solution for it?

Best regards,

See ANSYS for the MATLAB AAS Toolbox interface.

is there any news about live data exchange between ansys and matlab?

The toolbox is now availabe for download from Mathworks File Exchange at

As of today, the provided link

http://www.ansys-blog.com/how-to-make-matlab-apps-for-ansys/

redirects to the Ansys start page. The latest ANSYS_aaS Toolbox I could get is 1.1.9, which officially works until Matlab R2018b. I couldn't get it to work with newer releases and also can't downgrade my Matlab release because I'm using some functionalities of newer releases. Is there any follow-up on this? Has Ansys aaS been discontinued?

Thanks for providing the new link. Still, the time stamp is from 2017 and according to the text, the toolbox works for Matlab releases from 2014b through 2016a. It would be great to get an update on the state of things (@Sarah Palfreyman, @MathWorks Support Team).
