Hi, Let me describe my problem which I'm trying to simulate. 1. I'm doing a dynamic analysis for 1sec with 1e-2 as an increment time with displacements as an output for some nodes. 2. Now I want to do another dynamic analysis for the same duration and increment, with the same model but now I...

I am simulating a drop test impact scenario for a hyperviscoelastic material in Abaqus Implicit. When I look at the results, I find that the total energy of the whole model reduces by 15%. The same simulation when run in Abaqus Explicit gives a constant total energy value. Which results should I...

Also for modelling the contact scenario more accurately, does improving the smoothness of the analytical rigid surface help? Can the smoothness of semicircular surface be further increased?

When using adaptive meshing, is it necessary that the mesh elements on the boundary and the contact regions be restricted to move along with the material???

@ Mustaine3. Correction. Abaqus does allow the use of Adaptive meshing for the viscohyperelastic material, for some modes of hourglass control. I have used Adaptive meshing with hourglass control set to relax stiffness and stiffness modes, but with no sucess. I have one element which getting...

@ Mustaine3 . I am modelling a hyper-viscoelastic material. Abaqus doesnt allow the use of adaptive meshing for this material type. Is there any way to get around this limitation?

Thanks!!!

I am simulating a impact scenario in Abaqus Dynamic Explicit. Abaqus throws up this error of "excessive distortion/ratio of wave speed ....greater than one" after executing certain time increments. Can anyone pls tell me why this error occurs when we run the simulation and how to remedy it?

Thanks for the reply Greg Locock. For now I need to do it only one way i.e from ADAMS to MATLAB. I find it very inconvenient to import ADAMS results to a excel sheet and then import this excel sheet to MATLAB everytime. Regarding ADAMS/CONTROL, I even read about it, but its not the thing...

Hi, Is it possible to import ADAMS variable to MATLAB aka co-simulating both for data exchange ? I have a program in MATLAB which makes use of some simulations results of ADAMS like contact force and positions.
