what is the suitable absorbing boundary for soil in ABAQUS/Explicit? ALID layers, infinite element, euler lagrange, CEL or etc. ?
I used infinite element and ALID but they didn't work well !
Hi Sohrab,
Could you please provide more information about what you're trying to model? If it's anything related to modeling seismic waves (P/Sv and/or Sh) I would suggest you also take a look at the code SPECFEM2D deigned specifically for this purpose. The software uses either Stacey Boundaries or Perfectly Matched Layers (PML). I've been using it for a while, and it's been a really useful code.

Thanks Dear Siavash,
I created soil model (2 and 3D) with impact load to record the data of geophones in order to draw dispersion curve(MASW that is related to Rayleigh wave). last month i worked on EFISPEC(Elements Finis Spectraux, free spectral finite element method code) and i couldn't install it ..
Actually, i have some problem to install and work with these kinds of code... I will be very appreciated to guide me for working on this software.
S. M. Best Regards
As for SPECFEM2D, you need a Unix-based OS. I have a dual-boot of Windows and Ubuntu on my laptop. You can download Ubuntu for free from their official website and have it installed alongside Windows. Then, it's pretty much simple. The SPECFEM2D manual from the link below takes you through the installation step-by-step. I had absolutely no background working with Unix operating systems, but you will get used to it quickly thanks to the really good manual. On the technical side, you can model MASW (Rayleigh and Love) with the code, and generate dispersion images from any configuration of receivers you define. In a nutshell, for this particular application, the code is superior to Abaqus. Please email me at [email protected] with any further questions.
