Hello. This video has been really helpful to get overall idea on modelling a railway track. I'm trying to assign absorbing boundary condition to soil layers and model interaction between sleepers, rail pad and rail. Do you have any idea on how to achieve this (I'm using ABAQUS for the first time). Thanks in advance

Why are you applying a geostatic first step to the entire model before building some parts? It seems wrong to calculate something in parts that have not yet been built.

@@pranjlm Hello, Why do I consistently encounter excessive deformations at a certain second of seismic acceleration when performing analysis with infinite elements, leading to the error message "The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element"? Is it because my infinite elements are failing to effectively absorb energy, causing energy accumulation that suddenly results in significant deformations at a specific time?
