Flux-MATLAB/Simulink Cosimulation Failed at the beginning

Recommended Posts

I've got license for Altair HyperWorks Student Edition 2018 and installed Flux 2018.1. Then I coupled the software with Matlab R2017b and set the necessary path in Matlab. When I tried to run co-simulation using Flux with simulink, however, it  failed and the following message was shown:


:(Could anyone tell me how can i solve this problem? thx

It seems that there is a path in Simulink that is not well parametrized. Maybe, that is the reason why your S-function is not able to find Flux.

I think Flux path should be indicated in Simulkin in order to properly do the coupling.

Best regards,


Thank you for your respond.

I have added Flux path into the matlab path , as shown below. The error is still there :-( 

Do you know why it "cannnot find installation file" in simulink?

Many thanks.

Yes Flux 2018.1 support coupling with Matlab 2017b. you need to check the path in Simulink.


Best regards.

It doesn't work yet. I think maybe you should test the co-simulation or give a detailed technical brochure in the next version of the software.

It seems that I am not the only one encountering the problem...

Hi sx1995, 

Is your problem solved? if Yes can you please write how it worked.  I am also having the same problem.
