Is there anyone who models the Lamb's problem using abaqus ?
As we know,
Lamb's problem is a basic one in elastic dynamics. It can be demonstrated by a pulse applied to a half-space. Through analysis solution, one can see the sequential arrival of P wave, S wave and Rayleigh wave at a ponit which is far enough from the loading point. This phenomenon is due to the different velocities of P wave, S wave and Rayleigh wave.
Now, I want to model the lamb problem with abaqus. But I fail to get the same result with analysis solution. Can anyone help me?
Nucleation and extension of a tether out of a planar disk and a vesicle.
see the video(1) (tether from a planar disk)
see the video (2) (tether from a vesicle)
The dynamical features of tether growth has been studied. The color map shows the difference of the monolayer velocities.

Sequential change of some parts in a Abaqus input file and running the code for each.
Hello everyone,
I am trying to run some simulation in abaqus, I need to change some input variables and run the code for new values and this should be an automatic process not by hand every time.
Now I want to check if there is any way to change some parts in a abaqus .inp (input) file (say the Forces or other BC's) and execute the code again in abaqus and store the results of each simulation.
Thanks in advace,

Abstract:
difficulties in modeling elastoplastic damage behavior of rock salt
Dear all,
I want to construct a constitutive relation to model the elastoplastic damage behavior of rock salt which is considered as an excellent host medium for gas storage facilities. Because rock salt is a kind of typical geomaterials, confinement sensitive and inclusion effect should be considered in the constitutive model. However, I have encountered many difficulties in the course of the study. There are some issues I am a little confused.
