    Best Graphic Card for ABAQUS

    Honestly, I don't think 2000 euros is going to get a GPU that is relevant for actual computing; pre/post will likely be your consideration. You may find this page useful: http://www.nvidia.com/object/tesla-abaqus-accelerations.html

    Can ABAQUS model upper and lower yield strength phenomenon during tensile tests?

    Dear all, Can ABAQUS model upper and lower yield strength phenomenon during tensile tests? Any thoughts or hints would be much appreciated. Thanks! Shawn

    Axisymmetric analytical rigid: multiple surfaces?

    @Mustaine3 That's a great way to do it too. Thank you!

    Axisymmetric analytical rigid: multiple surfaces?

    OK - got one answer from SIMULIA Learning Community, credits to Matthias Ernst: "No. In the input file one analytical rigid is one surface keyword. And that surface is used in contact. Maybe you get it done by creating two analytical rigids that are placed right beside each other. You can...

    Axisymmetric analytical rigid: multiple surfaces?

    I have a simple model - an axisymmetric analytical rigid body, with the shape of a rectangular. I'd like to assign different friction coefficients to different edges on the rectangular. However, when I select surfaces, all the edges are always connected to be one surface. Is there a way to...

    Obtain nodal force in APDL Time History Prostprocessing

    Dear all, Before, when I applied a displacement on Node #X (actually a pilot node on a rigid body), I can use RFORCE command to extract the reaction force after POST26 (Time History Prostprocessing) Now, I am applying force load on Node #X (also a pilot node on a rigid body), I'd like to...

    How do I output displacement at a point on rigid body?

    Thank you marianw88 and assafwei! I made it work with a very similar method as you mentioned. Currently I used remote point to probe the displacement and force, as it is allowed to have remote points on rigid body; I never tried to use the coordinate system method and it sounds much better. I...

    How do I output displacement at a point on rigid body?

    Dear all, In ANSYS Mechanical (not the APDL), can I output the displacement at a point (vertex) on a rigid body? I tried User Defined Result which exported all displacements at all nodes. But because the rigid body is not meshed, there are no nodes nearby the point that I want to probe. Any...

    What is the stress obtained by position=ELEMENT_NODAL in odb?

    Dear all, I have a quick question: import odbAccess odb = odbAccess.openOdb(odbFilePath) frame = odb.steps[stepName].frames[frameCounter] frame.fieldOutputs['S'].getSubset(position=ELEMENT_NODAL, region=myNode) What is the stress obtained by this command? Specifically, 1) Is this averaged...

    Displacement-Controlled Indentation of Rubber Membrane--Reaction Forces too Low

    +1 to Me09. Neo-Hookean is non-linear per se, but IMO it is not "non-linear enough". Try Mooney-Rivlin, and if that wouldn't work I'd suggest try Ogden. If Ogden still won't work, then probably you could share your inp file with us?

    Model cannot proceed at all after switching to force load

    Hi corus, Oh man thank you sooo much! It is so obvious but I didn't think of it. I realized that the numerical singularity is coming from the contact (from the .msg file, the solver does not realize the contact at all). I tried to add a small force to push it into contact but it didn't work...

    Model cannot proceed at all after switching to force load

    Hi all, I have a very small model that runs perfectly under displacement loads. However, when I switched to force loads, the model cannot even move one step at all. Would you please help me with this? Thanks! Attachment: the inp file https://copy.com/8mpoUT8BtjfS Figure 1. The model...
