I am current using 3D model to simulate cylindrical waves but very slow. Is there a way to do it with 2D configuration? Thanks!

Hi, I have an very large input file which takes a long time in running "package_dp.exe" rather than solving the problem. The reason the input file is long is because the elements in the model are subjected to different body force loads. I have been looking at VDLOAD subroutine but it is still...

Hi, I wonder if there is a way to convert body force loading to equivalent nodal force loading? Thanks a lot!

Hi, I am studying the UMAT manual. The shipped example for modeling viscoelastic material gives a lot of insights. But I have a question: What is relationship between the parameters for the model (mu1, E1 and E2) and the parameters to the subroutine (lambda, mu, lambda_hat, mu_hat and nu)...

Thanks! It seems like an very interesting option. Are there examples about how to use embedded elements to model anisotropy + viscoelasticity? Thanks

Hi, After reading abaqus manual, it seems that the time constants are the same for both directions of transverse isotropic materials. Is it true? Is there a way to make time constants independent for the two orthogonal directions? Thanks!

Hi, I am trying to setup a 2D plannar model with acoustic infinite elements along the boundaries. From the help document, it seems like acoustic infinite elements can be created in CAE without manually edit input file (am I right?). Here is the steps I have tried: 1. create a 2D plannar...

Hi, I am trying to simulate the wave propagation process on a elastic material, which is surrounded by water. I am having the following error message when I try to run: AN ACOUSTIC MEDIUM IS DEFINED FOR ELEMENT 50 INSTANCE WATER-1. ONLY ACOUSTIC ELEMENTS MAY HAVE THIS MATERIAL PROPERTY. I...
