Whether the derived contact force is a single contact
Is the data derived from the contact force the force of a sing.le contact at this moment, or the total force of all contacts at this time? I saw that there is a textbook that says that it is a single contact, so I want to verify the following. Thank you.

How to more easily export AcuProbe results from multiple simulations of SimLab? Also, what kind of r
Hello experts, I've been running a large number of simulations in SimLab and need to export the AcuProbe results for each one. Currently, I have to open the log of each simulation and manually export the results, which takes me around 2 hours or more just for this task. Here you can see a folder showing a quarter of the…

Missing Rbe3 element in HM-v2024
I am working on the task with HM-v2024 with the interface of ABAQUS, here I need to create RBE3 → COUP_DIS element, but I can not select this type of element when using "RBE3 Elements", only the type of DCOUP3D is available. Then I go to the Preference page to check, still missing COUP_DIS element that I need. Could you…

Oka wear model - Wrong behaviour when using deformed geometries
Hello, I am working on a wear simulation of tillage tools. I need a particle bed for the process simulation. The particle bed is supported at the bottom by a geometry element. At the sides, however, periodic boundaries are used for support. Now to my actual problem: The geometry element at the bottom should not actually…

ERROR 31061: ADAPTFEKO run will terminate now due to error in RUNFEKO
I am trying to generate a 15x15 rectangular patch array. I have started by using the component library and specifying a frequency for a single element. This single element runs. when I create a 4 x 4 array and change the properties of the substrate, change the Cuboid1 width (W) so that elements do not overlap, and run the…

Machine Learning Modeling: How to fine tune models
During the modeling process, we typically select the best performing model to use for our predictions. However, there are times when the models do not predict within a set level of accuracy. In these cases, we must modify the parameters of the model to 'fine tune' it to be more performant. This session focuses on how we…
