    Implementing Periodic Boundary Conditions

    Hi, My project involves simulating forging process with a die pressed against a workpiece. I have a 3D model consisting of a cuboidal workpiece(blue) and a die(grey). I have attached pics of the model. I've looked at a number of forum posts but couldn't find proper instructions on how to...

    Periodic BC vs symmetric BC

    Hi, I have to simulate a forging process where the die has a sinusoidal profile given by z = sin(x)*sin(y) and has around 30 wavelengths(picture attached). I plan to do it by modeling one wavelength as modeling the entire (or quarter) die would be very tedious. I have attached the picture of...

    Excessive Deformation!

    Hey, I am not very experienced with abaqus so I might not be able to exactly point out your error but I got the same error myself. I kept tuning the mesh and went from a several hundred to 1 excessively distorted element. I too learnt about the ALE and adaptive remeshing but found that it would...

    quasi static coining simulation

    Thanks for your reply! I guess you're right. The second one definitely seems wrong. I think the first is right.

    quasi static coining simulation

    Hey, I am trying to simulate a quasi static coining process. I am using Abaqus 6.11 and an Explicit step. My model basically involves a die with a sinusoidal profile pushing on a cuboidal blank. I have specified a displacement boundary condition where the die pushes into the blank. The...

    Quasi Static forging process

    I've been doing the examples given in the official documentation. So I've got some amount of practice. The normal interaction was specified. Could the time period of the step be the reason?

    Quasi Static forging process

    Hi, I have just started getting the hang of Abaqus and was trying to simulate a quasi static forging process with a sinusoidal die profile. I have used a dynamic Explicit step and specified the surface to surface contact between all the right surfaces. Yet, when the simulation runs, the die...
