I am trying to run an example, provided by altair on their help page, about vibroacoustic interaction and wave propagation using infinite elements CACINF3. The link to the page is:
https://altairhyperworks.com/hwhelp/Altair/2017/help/os/topics/solvers/acoustic_analysis_of_speaker_os_example_r.htm#results
However, I am unable to run the problem using optistruct 2017.
The error message given is:
The model file follows attached.

Above shared model runs fine at my end with latest solver OptiStruct 2018.0.1 patch.PFA h3d and out files for your reference.
I do not have access to the latest solver patch. I am using OptiStruct 2017.2.
However, the model was supossed to run with this solver. The link I have provided is from the 2017 help page.
Am I missing something?
Shared file runs fine with OptiStruct 2017.2.4 patch. I also see in the resolved issue list of OptiStruct 2017.2.3 which takes about Infinite element. PFA screenshot for same.
