    Layers of Composite Shell Section

    Thank you FEA way, you're great! Have a nice day :)

    Layers of Composite Shell Section

    Hi there! I would have a question regarding the creation of a composite shell section. I have two layers, one of aluminum, and one of polypropylene. I am wondering how I can know which layer is on top of the other (see image)? In my case here (I have clicked on the iso view), is the PP always...

    Symmetry Boundary Condition Circular Edge

    Thanks FEA way, it worked out perfectly!

    Symmetry Boundary Condition Circular Edge

    Hi there! I want to apply a symmetry boundary condition on a circular edge. The shell part (see image), is a slice of a disk. I then trimmed the part at its origin, resulting in this short circular edge on which I want to have a symmetry boundary condition (to account for the missing part of...

    Boundary Conditions on Deformed Configuration

    I will try to sort this out myself as these issues seem to come from the fact that I called my parts with two words in the simulation of stage-1 such as "Tool One" which seemed to be problematic.. If you could just help me on these two last questions, I'd be grateful : - As far as the more...

    Boundary Conditions on Deformed Configuration

    Okay, but then, in my simulation of Step-2, will it automatically take the displacement boundary conditions of the tools (e.g. 10mm z-displacement of tool A...) with respect to the deformed configuration at the end of Step-1? EDIT : I followed the 4 steps you mentioned, and obtain the same...

    Boundary Conditions on Deformed Configuration

    Okay now I totally get it. I thought importing deformed parts was needed.. But is it then correct that I need to tick the "Update reference configuration" when creating Predefined-field > Initial state ? If not, how does abaqus know that displacement BC's are now defined with respect to the...

    Boundary Conditions on Deformed Configuration

    Yes exactly, this occurs when importing the deformed mesh from .odb. I found the template you mentioned, I will try look into it. So there can be issues when using this import from .odb option which can be avoided with this *import keyword? As for your other suggestion, what do you exactly mean...

    Boundary Conditions on Deformed Configuration

    Alright, now it's clear, thanks! I've been doing what you told me to do, ran the input file for the step-2 simulation, but the Analysis Input File Processor exits with an error (pasted relevant lines only): ***ERROR: The surface ASSEMBLY_SHEET_SHELL-1_CONZMAX has not been defined. LINE IMAGE...

    Boundary Conditions on Deformed Configuration

    I have indeed found the .mdl file by now, I wasn't looking well enough.. Another question I'd have is that when I import all the deformed parts of the stage-1 simulation, old sets appear with different namings as well as new sets that I had not defined in the stage-1 model. Can I delete all the...

    Boundary Conditions on Deformed Configuration

    Alright, thank you! When running my step-2 simulation, it returns me an error saying it needs a .mdl file. I don't really know how to generate this model file (which I don't get by default when running my .inp), could you help me on that? Also, I'm still confused why use the term "restart". I'm...

    Boundary Conditions on Deformed Configuration

    Alright, perfect! What I did was simply importing all the parts from the .odb of step-1 simulation, and then create these instances in the assembly module. But will there not be any difficulties for Abaqus at the beginning of the simulation to initiate the contact analysis since everything is...

    Boundary Conditions on Deformed Configuration

    Hi FEA way, Thanks for your response. I had indeed missed that. I read it throught but am still a bit confused : - When choosing Predefined field > Other > Field, do I then need to choose "From results or output database file"? So this means I need to simply run a first job with the model...

    Boundary Conditions on Deformed Configuration

    Hello there! I'm modeling a forming process in which I have the following : - A first step in which the forming tool performs a first deformation of the metal sheet. I have used displacement boundary conditions (BC's) to model this (e.g. z-displacement of 10mm, encastre BC's, etc.) - I want to...

    Deactivate Coupling constraint

    Hi FEA way, Thank you for your response. I'm not really used to connector elements and couldn't find my way around it, how would it work out in my case? Both of the tools that should be connected are rigid, and have the same symmetry axis (the parts are axisymmetric imported rigid surfaces)...

    Deactivate Coupling constraint

    Hi everyone! I'm simulating a deep-drawing analysis on ABAQUS CAE. In the first step of my simulation, I have a coupling constraint between two of the tools such that one tool has the same z-movement as the one from tool 2. The results after this first step are correct. But now I want to add a...
