    Workbench meshing automatically updates and increases relevance

    @ L_K Thank you for your offer. I managed to tweak the geometry model, and the meshing is the same. Possibly something I oversaw in the geometric model. The mesh settings were identical in both models.

    Workbench meshing automatically updates and increases relevance

    I am doing a comparative study, which means I have 2 very similar models, but with some small differences in geometry. I would really like to have identical mesh, as the differences are quite small and the results will be affected. However, in one of the 2 models, Meshing automatically updates...

    ANSYS Workbench - Reaction force in specific point at edge of contact

    I have a pair of cylinders in contact, one inside the other. The inside cylinder is longer than the outside. When I use Reaction Force probe for the contact, it calculates the total reaction through the entire length/area that is in contact. Is there a way to calculate the reaction force only on...

    Reaction force direction in contact area vs fixed support

    @ Erik Panos Kostson, Thank you, this makes some sense and I tried the "Target" behaviour and the results were as you described them. So the reaction forces plotted negative are correct? In reality I am more interested in the result that would be the nodal force sum (FSUM in APDL) for a...

    Reaction force direction in contact area vs fixed support

    I have come across a problem I cannot explain, and I hope someone could explain it to me a little. I have a solid cylinder going through two fixed cylinders, with automatic contacts in between (a bit like shaft and bearings). The outer face of the support cylinders are fixed. When I run the...

    Meshing takes long time - how can I check which geometry it's at?

    @Erik Panos Kostson, Thank you very much for your help and this advice. Unfortunately, I cannot see the "highlight" box in my meshing status window, as you can see: . I have Ansys 16.1, does that make a difference? Again, many thanks for your help!

    Meshing takes long time - how can I check which geometry it's at?

    I'm meshing the model. Admittedly, it might be a little complicated, as I have transition from very small geometry (a few mm) to about 100 times that size and I don't need all the elements to be that small. I'm using Contact Sizing in the area I'm interested to be as much as the small elements...

    Reaction force probe in contact - underdefined how to define properly?

    @ Erik Panos Kostson, Thank you , that did the trick!

    Reaction force probe in contact - underdefined how to define properly?

    I am trying to create a model to judge the reaction forces between two elements in a contact. It is a static analysis, I have not progressed it to nonlinear. The contact is bonded. When I try to insert the reaction force probe and I choose the contact I want to explore, I cannot get it to define...

    Contact Tool not producing initial results

    @Erik Panos Kostson, thank you so much for your input! I did run with no contacts and it solved fine (rubbish deformation, of course). The first contact pair I tried to activate failed in the same way - element normals. I guess that's were the problem is, although I am using exclusively solid...

    Contact Tool not producing initial results

    @ Erik Panos Kostson , thank you for your input. I am already only doing linear analysis with bonded contacts, as I am still figuring out how they work. I meshed the model. Due to its geometry, I have some rather small elements and some larger ones in the connected bodies. I want to run...

    Contact Tool not producing initial results

    L_K, thank you. Does that mean I should mesh it first before using Contact tool? I have imported my meshing methods and sizing, and when I try to mesh it "separately" - without contact took, it meshes well.

    Contact Tool not producing initial results

    Hello, I am relatively new to contact elements, I work in Workbench 16. I am trying to model a contact and have some issues with it, so I decided to try the Contact tool. However, it does not produce any results when I run "Initial Information", and the error messages are :"The mesh generation...
