    Issue in Running the jobs

    How large are your models (in terms of the number of DOFs, nodes or elements) ? Do they contain any non-standard features ? Characterizing them a bit may help choose the proper settings to reduce memory requirements.

    Abaqus-CAE : Radial Partition

    The above pictures don't explain how (not what) should be partitioned. Maybe for now make 2 parts of it - duplicate the part and cut the unnecessary segment from one copy using CAD operations, then assemble the parts together and color them based on instances.

    Fatigue simulation

    I'm not sure what you mean by load time history. Response from Abaqus ? For nonlinear analyses, you can't use the superposition (scale and combine) approach in fe-safe to multiply the frame with Abaqus results by a given signal. You have to use the dataset sequence loading where a series of...

    Cohesive zone modelling experimental input for simulation compatibility

    This YouTube tutorial is interesting but if you are comparing with experimental results, research papers might be better. Maybe you can find one with a similar setup. Just as an example, "Modelling of Single-Lap Joints Using Cohesive Zone Models: Effect of the Cohesive Parameters on the Output...

    Abaqus-CAE : Radial Partition

    I'm not sure how you want to partition it and where that 200 mm dimension is. It would be better to mark it on the 3D model. Do you want to partition only the surface or some volume ? There are different partitioning techniques for faces and volumes. It will be much easier if it's possible to do...

    Mesh Convergence Test

    Check the following chapter of the Abaqus documentation: Benchmarks --> Analysis Tests --> Static stress/displacement analysis --> The Hertz contact problem. There you will find a similar case. Not 3-point bending but here it's also more about contact between the indenter and larger sample. Is...

    Problem during linking - Abaqus/Standard User Subroutines

    Did you try running subroutine verification procedure and some simple subroutines from the documentation to make sure Abaqus is properly set up with the compiler ?

    Nodal coordinates and the strains at the nodes

    Not a Python script ? If you need those nodal results for further use in a subroutine, check this thread: https://www.eng-tips.com/viewthread.cfm?qid=467050

    Connector Damage/Failure

    Damage behavior for connectors is simplified and you can define the initiation only in terms of forces/moments, equivalent plastic displacement/rotation or relative constitutive displacement/rotation in the connector. Maybe in your case it would be better to replace the connectors with beam...

    Hybrid Meshing in ABAQUS

    Abaqus has wedge elements for some transitions. Pyramid elements are supported by the solver but not by the GUI (Abaqus/CAE) so they would have to be generated in external mesher. If incompatible element shapes are assigned for contacting regions, Abaqus shows a warning and creates tie...

    Help Needed with Hot Pressure Stamping Simulation in Abaqus

    You should ensure that it makes sense physically (compared to the real-life process). For example, the velocity shouldn’t be unrealistically large. Check the influence of mass scaling too. Similar issues may occur in deep drawing simulations when the blank is fixed on the edges instead of...

    negative buckling eigenvalue (Abaqus)

    You can find some tips regarding this in the documentation chapter Analysis —> Analysis Procedures —> Static Stress/Displacement Analysis —> Eigenvalue Buckling Prediction (paragraph "Understanding Negative Eigenvalues").

    Convergence issue for a model with driver nodes

    Ok, but you have to eliminate rigid body motions to achieve convergence in a static analysis. There are various ways of dealing with that. Here, you could e.g. try adding soft springs to stabilize those unconstrained directions.

    Nodal coordinates and the strains at the nodes

    If you only want to read them, you can use the existing outputs (strain variables and COORD) and postprocessing tools (even the Probe Values tool can read integration point variables like strains extrapolated to nodes).

    Convergence issue for a model with driver nodes

    I assume that you constrained only the translational DOFs (1-3). Why did you leave the rotational ones free ?

    Warping in FDM simulation

    You can use contact or tie constraint between the part being built and the build plate normally (like in a regular analysis without AM features). There are even examples like this within Abaqus documentation and other resources. Symmetry will be more tricky to use because you would have to take...

    Regarding taking resisting torsional moment of the beam from FE results

    This reply should be applicable here at least to some extent: https://www.eng-tips.com/viewthread.cfm?qid=523210 Knowing what I explained there, is it also clear to you in this case ?

    Abaqus step file import error

    And you can't update to a newer version of Abaqus ? A few bugs like this were fixed. Some were caused by non-English OS locale or non-English characters in the user account name.

    Warping in FDM simulation

    How is the real part supported ? Is there any symmetry plane to use ?
