I'm trying to investigate the effect of multiple support excitation (spatially varying ground motion) on seismic response of an arch dam using ADINA, so i need to apply different acceleration (and velocity and displacement) time histories on every node on structure-foundation interface.
I've to model a gearbox in the transitory (acceleration) and in the
stationary (constant speed) running: i'm not sure abut the kind of step
I'm gonna find contact pressure and stress in both case.
I need some help with MIMICS software please. I have a CT scan images for the whole body and i need to create 3D object for the shoulder model to each part Humerus and Scapula and then perform some measurments then Export it to ABAQUS. Does any one have any idea. Please help.
I would like to know whether there's any method to submit a
number of Abaqus implicit jobs at once (like letting it to run whole
night without any attention)? Also is there any way to run those jobs
without opening Abaqus CAE (like in the command prompt) in a computer
with Windows vista? I have modeled everything in CAE.
We tried to simulate simple shear using ABAQUS and compared it with the analytical solution. To our surprise, even though the equivalent stress and strain matched perfectly, the component stress and strain had a large deviation between the semi analytical and ABAQUS methods. The zero components in the analytical model were calculated to be non-zero in the results of ABAQUS. This paradox could not be understood clearly as whether it is a case of software deficiency or conceptual error. A COMPLETE ANALYSIS OF THE PROBLEM IS ATTACHED AS A REPORT.
I have a problem with applying periodic boundary condition. I have used *EQUATION in constraints for opposite nodes and surfaces. But I still have some problem with that for sure I making some simple mistake. If anyone could look at my model and find problem. Abaqus version 6.9-1 .
Thanks a lot.
All, I am conducting a survey and your response would be very much appreciated. The purpose of the survey is to gather data that will help the developers of open source software improve the success of their projects. All replies received before midnight Sunday 26th September will be entered into a draw for a £30 Amazon gift voucher.

I'm programming by myself to do the simulation of forming process. I met the problem below. [img_assist|nid=8910|title=probelm|desc=penetration in adaptive remeshing|link=none|align=left|width=60|height=100]
I used second order triangular elements and h-refinement method in the simulation. When the workpiece(bottom) is remeshed, the new node is inside of the tool(upper). How can i solve the problem?
I have written a Fortran code for nonlinear viscoelasticity according to the Hughes' recurrence algorithm based on a total Lagrangian formulation. And a relaxation test is made. There is some deviation from the analytical solution(Theoretically the stress response should be an exponential decay plus a constant, isn't it?). The numerical ultimate stress is larger than the analytical one. As a larger initial strain is applied, the deviation is smaller. For a inital strain of 10%, there is almost no difference between the num. and analy. solution. What can account for this?
i am doing static analysis on a pick and carry crane, i need to find the pin forces. for this i created entity set with the nodes where the forces are to be derived and ran a static analysis in ansys.In order to derive the forces , i first picked the entity set and then applied the nodal loads from the list result options. the result that i got was not fine. it states there was zero forces on the pins, but its not.i need to find the pinforces, so kindly let me know , how to do it.
