Acoustic simulation: Infinite elements

Recommended Posts

Hello everyone,


currently I am working with Infinite elements. I modelled infinite elements according to the manual provided by Hyperworks. 
I have been trying since Long to get results on PLOTEL. I don't have results on PLOTEL, I don't know why. 

Could anyone please help me out? Model is attached for reference. 


Thanks in advance. 

Vikrant Tailor.

l looked in to your model last week and it seems you have modelling issue. Elements are not interconnected in your model. Also there is some modeling guidelines for infinite elements.

It would be good if look at speaker model from example guide which we shared earlier.refer Optistruct online help for details.

In Hyperworks Manual, it is not clearly mention, if one should have coincident meshing or not. 
That is where I am stuck. I just need clarification. because it is difficult to have coincident meshing in this model.
