Unable to Open Aspen Dynamics file in Matlab Siimulink.

[Walter Roberson]

I do not find any evidence that AMSimulation.Setup is the correct ActiveX progid. The evidence I find for 'apwn.Document' followed by version number information

[Ayan Sil]

Can you please tell me what to do?

[Walter Roberson]

Unfortunately AspenTech's documentation is confusing about what exactly what "Aspen Dynamics" is compared to "AspenOne" or "Aspen Plus" or "Aspen HYSYS Dynamics"... and finding the Active-X ProgID information is difficult.

What is the exact name and version of the software that you are trying to interface with?

I have encountered a similar error. How can I solve it? The version of my MATLAB software is R2022b 64-bit, and the version of Aspen Plus Dynamics software is v10 64-bit. Thank you.

Hello,

I understand you are unable to Open Aspen Dynamics file in MATLAB Simulink.

Please ensure that Aspen dynamics model which you are using is 64-bit after V10 version because MATLAB uses 64-bit in releases starting with R2015b. As a result, Aspen Plus Dynamics prior to V10 will not work with MATLAB R2015b and above.

For additional information about Aspen Plus Dynamics, please refer to the links below:

I hope this helps you to resolve your issue!

To be more precise:

R2015b is the last MATLAB release that supported 32 bit Windows. MATLAB first started supporting 64 bit Windows in R14SP3 (note that does not mean R2014; R14SP3 was released September 1, 2005)

I had the same problem,I'm using matalab2018 (64-bit) and aspen dynamics (64-bit) V12, did you fix the problem
