New Absorbing Boundary Condition

[abbasp]

Dear fmk,

Hi,

I want to add a new element to opensees. In details, I should add a new kind of absorbing boundary in FEM.
For this, "Perfectly Matched Layer" is my purpose which is going to be added in OpenSEES. So, is it possible to do this with OpenSEES?

Best Regards.
Abbas

Thanks.
Could you please give me a sample in OpenSEES which is similar to an absorbing boundary in order to start with it? i.e. to modify it in order to build "Perfectly Matched Layer"?

[fmk]

there is nothing that similar .. start with an elastic beam column element as it will have the least amount of code to keep. or you could start with any of the continuum elements.
