    Material units

    Consistent commonly used SI(mm) units are: - Young’s modulus [MPa] - density [tonne/mm^3] - thermal conductivity [mW/mm*K] - specific heat [mJ/tonne*K] If you search for "Abaqus units" you will find some helpful tables with other consistent unit systems.

    Hinge Interconnection Not Working – Only One Shell Part Moves

    Did you attach those reference points to the plates ? You can do that via rigid body or coupling constraint.

    Excessive Distortion in Press Hardening Simulation

    You should always check the warnings. Here you have unconnected regions, negative eigenvalues and numerical singularity messages. Check the nodes where issues occur. You can use the Job Diagnostics tool to highlight them. This is easier than reading plain .msg files. Another way is to upload...

    Interface fracture mechanics - Why isn't ENRRT11 = GI?

    How far are they ? Is it Abaqus/Standard or Explicit ? Are you using viscous regularization ? Did you check the standard energy outputs (especially ALLSD and ALLVD vs ALLSE) ?

    How to reduce fiber damage

    Have you seen the DS Knowledge Base article "Abaqus/Explicit VUMAT for the simulation of damage and failure in unidirectional fiber composite materials" ? You should make sure your setup doesn’t differ significantly from the reference experiment. Some calibration of material data might be...

    Trouble Meshing Imported SolidWorks Part in Abaqus – Need Help with Hex or Hex-Dominated Mesh

    This geometry is yellow (sweep meshable) right away but you will get invalid (distorted) elements if you use the default settings. You should assign proper global and local seeds and apply one transverse partition in the middle. Then it will work.

    Mesh singularity on non-manifold geometry

    There are also composite sections for solid elements so you can use layups with them. This is often used e.g. when analyzing nozzle regions of composite pressure vessels.

    Abaqus-Isight

    Try these steps (based on the aforementioned KB article): 1. Add the subroutine file as Input files parameter in the Abaqus component. 2. Enable the Fixed file name checkbox and specify the Fortran file name in the Destination section. 3. Add the user command to the Abaqus command. 4. Make...

    Mesh singularity on non-manifold geometry

    You could use submodeling or shell-to-solid coupling to model that small region with solid elements and including some fillets thus obtaining more realistic result.

    viscoelastic behavior + Damage

    I'm using the documentation for Abaqus 2025. It can be accessed only via 3DPassport account but anyone can access it. This is only mentioned once in the chapter "Damage Initiation for Ductile Metals": If it doesn't work this way (which is understandable considering the individual limitations of...

    viscoelastic behavior + Damage

    According to the "Damage Initiation for Ductile Metals" documentation chapter, ductile damage can be used with PRF and permanent set for rubber-like materials.

    universal joint

    Can you share a screenshot of this model showing the bars and how they are aligned with the global CSYS ?

    Splitting part while keeping mesh

    If you want to split it at the interface between element layers, you could use the Create Mesh Part tool to get orphan mesh and delete proper element layers from each copy. Regarding connection of separated regions of the same part, you can use tie constraints for that. Abaqus does it...

    NMAP Cyllindrical Usage

    Most likely access is limited to users with commercial accounts and that’s why you can’t see it.

    Abaqus-Isight

    What version of Isight are you using ? If you have access to Dassault Systemes Knowledge Base, check the article "Running Abaqus jobs with user subroutines in Isight". What is the error message ?
