    issues with abaqus example "Fully coupled thermal-electrochemical procedures"

    I would like to use the verification problem named “Fully coupled thermal-electrochemical procedures” from Abaqus documentation to study the thermal-electrochemical behavior of a lithium ion battery using Abaqus 2022. However, the input files provided with the verification problem are not...

    Resultant Shear Stress in ABAQUS

    Hello I am wondering if there is any way to visualise the resultant shear stress on a part? I have two objects in contact and produce shear stress in different directions. Like CSHEARF magnitude force, I wonder whether there is any way to calculate the resultant shear stress on the surface...

    Problem in boundary condition to move object as the result of external pressure

    Hello I am trying to simulate a force being applied on a cylinder inside an object encompassed by another semi-conical shape object. Sorry, to make the explanation clearer, I named the parts (objects) inside the model and attached its image. Similar to the attached image: Object A is tied inside...

    Why trust-region-reflective algorithm in fmincon require a gradient as input in MATALAB

    According to Matlab fmincon documentation, the 'trust-region-reflective' algorithm needs to specify the objective gradient. I read the algorithm explanation but yet, I cannot understand the reason for that. 1- Why does it need gradient as input? 2- Does the objective function have to be...

    Fill a gap between two surfaces, using pressure as variable

    Hello According to the attached picture, I have two surfaces (Master surface and slave surface) where there is a gap between them. The slave surface can be inflated with the pressure "P". I aim to find an appropriate "P" magnitude to fill the gap and only TOUCH the master surface without...

    Measuring the Hessian matrix for lsqnonlin in MATLAB

    Hello In MATLAB, I am optimising a multiobjective function using the lsqnonlin function with the trust-region reflective algorithm. I was wondering how I can get the hessian matrix as an output? Matlab provides a matrix of Jacobian,is it possible to calculate Hessian matrix using the Jacobian...

    Map PointCloud to the mesh in visualisation module

    Hello I have 3D point clouds obtained from 3D image reconstruction, and I have also run a simulation with Abaqus and got the result. I am trying to map the points obtained from the point cloud on the mesh and show them. I followed the instruction in the documentation, but I do not know how can I...

    ABAQUS Index numbering for the surface

    Hello I am trying to use python script to generate new surface in order to apply pressure on it using script. I use the: session.journalOptions.replayGeometry session.journalOptions.setValues(replayGeometry=INDEX) to achieve the index number, but the problem is that I cannot understand the...

    Find the ID for faces.getSequenceFromMask

    Hi I have a cylinder with pockets in it, then use script to generate new pockets in different plane angels. The problem that I have, I do not know what is face ID for the new generated surfaces? since in the GUI I manually select the faces and it gives...

    PREPRIN Error in input file

    Hello I am trying to run a job by importing the INP file. but I face the following error: I use Abaqus/Explicit in case it matters. Does anyone know how to resolve ir? Thanks

    Run ABAQUS INP file in any other software without using ABAQUS licenses

    Hi All I have many ABAQUS INP file that each of the require several ABAQUS licensee for each job submission. I am aware of many different script that submit INP file to the ABAQUS without opening it. But, I am wondering if there is any package and scrip or software etc that is able to process...

    Multi-step analysis with dynamic implicit

    Dear All I am trying to do an analysis that includes two steps, both steps are dynamic implicit but with different configuration and each of them have various configuration. The problem that I have is that, when I apply a pressure in step one, although I have deactivated in step two, it...

    Read point list from a CSV file in Abaqus

    Hello I am trying to generate a Path in abaqus using a script, but instead of feeding the path as coordinate manually, I want abaqus read a CSV file and generate a path based on that, but I get the following error: TypeError: expression;found 'file', expecting a recognized type filling string...

    Achieving specific surface shape

    Hello I developing a model, in my model I want that the surface of my sample become similar to a desired shape by manipulating the inputs which are the pressure in each chamber, thickness and the chamber diameter. Is there anyway that ABAQUS would manipulate/optimise the parameters so the...

    Reading Data from MS5803-05BA

    Hello I am trying to read the pressure data from MS5803-05BA through SPI interface via Arduino Uno. I have designed my PCB (schematic attached), I am now trying to communicate with it using the attached code which is modified version of the I2C code. However, The only output that I get is 0...

    Find time period in dynamic implicit step for a quasi-static problem

    I am modelling a large deformation with hyperelastic material. Technically I have a quasi-static problem, I inflate a balloon using pressure, but since it is large deformation static general module is not able to solve it; hence I am using dynamic implicit. Obviously, for a different time period...

    Set displacement limitation for the applied load

    Hello I have a soft actuator, which is being inflated using internal pressure which results in the surface displacement of this soft actuator and reaches to, for instance, about 5mm of displacement. I need to apply external pressure against the surface, but I need to keep this external pressure...

    INP data drifts

    Hello In my model the pressure changes, I have 20 job with 2o different pressure input which starts from 1 to 60 kpa. I run the python script and generate the INP files, in those files the pressures are allocated to each INP file is appropriate, but when I submit the job,I understand that it is...

    Set multi model for one hyper-elastic material?

    I am trying to model a hyperelastic material in Abaqus, but after evaluating the material properties, it seems that the Neo_H model is appropriate until 50% strain, and then Ogden-1 is suitable. How can I set in the Abaqus that it uses Neo-H until 50% strain and then switch to Ogden? Thanks

    Node number update

    Dear all I am using python to generate a shape that the thickness and mesh size of it and hence the node number of it changes by each job. I want the displacement of a specific part of geometry (attached), but I`d prefer to find a code or a solution that Abaqus automatically find the path for...
