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...

Your solution resolved my issue. I created a new field output based on the existing field outputs. Thank you so much

Thank you for your responses. I need field output. The filed output generates the resultant shear force. Is it possible to define a field output that dived this resultant shear force by the corresponding element area? Since I need resultant shear stress rather than resultant shear force. Thank you

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...

Thank you for your help. You are right, the density unit was wrong. I changed it and it is working ok.

Hi I have attached the CAE file. You can download the ODB results from here. Yes, it can be said that object A is a bone, object B is a residual limb and object C is a socket for that. Object A has steel properties. Objects B and C have hyperelastic properties...

Thanks for your response. I have checked with displacement control, but there was no difference. Since the change in the stress on contact between objects B and C is absolute zero. there should be an initial clearance, then after applying the force and the object B comes down, B and C should...

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...

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...

Thank you Mustaine3 for your response.

Perfect, thank you for your response.

Thank you for your response, I am not sure if I have understood you solution completely. I use quasi-static in dynamic implicit with 60 sec time. Let say that I use P=500 kPa which I am sure it is way more than enough and ABAQUS solve it in 120 increment (0.5 time step, and no backward...

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...

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...

Thank you so much, I will have a look into that. I am wondering does it interpolate the result for the nodes that I have not defined? For instance, my analytical solution returns the result for 60 nodes out of 500 nodes. Does Abaqus interpolate to visualise the rest of 440 nodes, or it will not...
