    Linux Cluster Parallelization

    I'm trying to run large Abaqus jobs on a Linux cluster using parallelization. I'm running into an issue where if I set (for example) my Abaqus job to use 80 cores, and submit a batch file requesting 2x nodes, with 40x cores each, the job will run on only 1x node and not utilize both. It will...

    Abaqus TEMP Output vs Input

    Yes, this is simulation of L-PBF using the AM plugin. I just compared values of NT11 instead of TEMP. This time, the values are the same! Time to dig in to the difference between TEMP and NT11. Thanks for the help.

    Abaqus TEMP Output vs Input

    I only have NT11 as an output (C3D8R). My mechanical analysis only has an encastre BC on the build plate portion of the model (not my part) and uses a predefined field to assign the HT values. I really don't understand where the heat could be going. It's a mechanical analysis, and the build...

    Abaqus TEMP Output vs Input

    Hey all, a quick question about AM simulation in Abaqus. Hopefully this is something simple I'm just not quite grasping. As you know, in thermo-mechanical simulation, it is a 2-step, sequential process. The NT output of the heat transfer simulation becomes the input to the mechanical. I pulled...

    Abaqus UTEMP Subroutine

    Having a lot of trouble with the UTEMP subroutine. I've been at it for awhile and can't get what I'm looking for. In Fortran, writing the subroutine, I am attempting to read in a 45x512 matrix of temperatures. The summary is: - INTEGER, DIMENSION(45, 512) :: U_TEMP !creates 45x512 matrix -...

    Abaqus Sequential Thermo-Mechanical

    For anyone with the same issue, here is what I did: -Generate report from ODB in Viewer GUI in CSV format -Run MATLAB script to identify temps above threshold value -Run MATLAB script to replace temps above threshold value with threshold value -Run MATLAB script to write to new CSV file -Use...

    Abaqus Sequential Thermo-Mechanical

    Good morning all, I'm running uncoupled sequential thermo-mechanical simulations (for AM). This means that I'm using the .obd file from the heat transfer simulation as a predefined field in the mechanical simulation. However, I'd like to do a temperature cutoff for the nodal temperatures that...

    Abaqus AM Modeler Plug In

    Hey all, question on the AM Modeler Plug In in Abaqus CAE 2022. I'm trying to simulate a DMLM print of a simple column with a sequential thermo-mechanical, pattern-based process. I thought I was familiar with the options in the plug-in and model, but when looking at the results, they don't make...

    Abaqus EEIG Output

    Yes, the files were generated with the plug-in, based on those examples. I need the thermo-mechanical eigenstrain result to feed into the eigenstrain part print simulation. I'm just confused as to why some outputs were successful, but EEIG failed without a warning message.

    Abaqus EEIG Output

    The only warnings I have are for 2x recoater interference in the msg file. The dat file has 4x: - THE OPTION *TEMPERATURE IS USED BUT THE OPTION *INITIAL CONDITIONS,TYPE=TEMPERATURE IS NOT. THE INITIAL TEMPERATURE VALUES ARE ASSUMED TO BE ZERO. - THE REQUEST FOR...

    Abaqus EEIG Output

    I'm working on implementing the inherent strain method in Abaqus 2022. In summary, I'm doing a small, sequential thermo-mechanical simulation in order to get eigenstrains that are then applied to a mechanical, part-scale simulation. I'm been able to run a thermo simulation that outputs NT...

    Abaqus 2022 Eigenstrain Additive Manufacturing

    Good morning, I'm trying to use the AM plug-in in Abaqus 2022. I've run into a few hiccups and am looking for help. The example found at this link, with the given input file, generates errors that variables are not recognized or supported, even though the file is directly from Dassault...

    Abaqus 2021 Additive Plug-In

    Unfortunately I do not have access to 2022. Just 6.14, 2018, 2020, and 2021. Is 2018 the latest version of the plug-in available on the Simulia site? There is nowhere else to get a more recent version?

    Abaqus 2021 Additive Plug-In

    Good afternoon, I am having issues with the additive plug-in for Abaqus 2021. I have the 2021 version, but I had to add the plug-in myself. However, the download on the Simulia website had only the 2018 version of the Plug-In. I'm looking to do eigenstrain-based simulation, which the...
