Hello, I have this simulation attached.
It is a frame and it is shell meshed. However I am struggling to run a simulation on it because I always get an excessive pivot ratios error. I have tried running Bailout -1 but to no help. Could not figure out where the error is.
Can anyone help me...
Hello,
I am currently involved in simulation of bending of aluminium sections. So far most of my simulations have been performed using Explicit solver as this is supposedly faster, however when using Implicit solver the results seem to be better, with less trouble with excessive...
Hello, I am going to restart analysis, I have added some local coordinate systems in the newly created step, but now I get the error message when trying to write the job:
"Since the current model is being used for restart analysis, the CSYS transforms for the following newly created attributes...
Hello,
I have a three point roll bending process where I am struggling with high distortion of some elements. The workpiece is moving from left to right in the image below. THe friction factor is 0 and the rollers are all discrete rigid. Does anyone have any suggestions on how to solve this...
I am currently running a dynamic explicit job in Abaqus, but the process seems to take longer than expected. I am considering killing the job, but I won't do that if I loose all progress.
Is there a way to kill the job, but at the same time ask abaqus to write results up until that point? Can I...
Hello,
I have a three point roller bending process for an aluminium profile. I decided to split the process into two simulations. The first simulation is to lower the top center roller down onto the workpiece to get an initial bending. This simulation(Model-1-exp-13mm), a dynamic explicit...
I was told by my supplier of Abaqus software that Abaqus will benefit from parallel computing up to 64 cpu cores. More than 64 cores show little benefit in computing time and beyond 128 cpu cores total computing time actually increases.
I am uncertain as to what type of simulations my supplier...
Hello,
I was wondering if anyone here could explain to me in a simple manner why implicit fea benefits less from parallel computing than explicit fea?
Hopefully awaiting intelligently elaborated replies easily understandable by a person whos mothertongue is not english.

Hello,
I have just started using ABAQUS for the purpose of simulating the bending process of an aluminium profile. See attached image for typical profile section.
The bend radius is not severe, but defects(bulging etc. ) do occur in practical experiments. As I am used to a program called DEFORM...
