Hi all,
Using WB 12, how can I grag the nodal positions for an area? For example, in classical, I select the particular area, then select nodes attaced to that area. I am interested in knowing the undeformed positions, and then the deformed position (displaced).
Thanks in advance!
Hi all,
I'm just starting out using DesignModeler with workbench 12. I know the classic version very well, and I am looking for the "glue" command. It seems that I am looking for Connect in DM...When I use this command it seems to connect the areas OK but I dont think the lines and nodes are...
Hi all,
I have a relatively simple question. I have a large model with many contact pairs. I need to remesh one of the volumes because I am not happy with the way the model runs. If I remesh the volume, will all the contact pairs associated with that volume's areas update? If not, can I...
Hi all,
I have an analysis running which seems to be getting stuck on 1 particular element. The output indicates "1 U-P ELEMENTS DO NOT SATISFY THE VOLUMETRIC COMPATIBILITY"
I am not so much concerned about the message because I encounter it all the time with hyperelastics. However, is there...
Hi All,
I have a working model which achieves convergence, but I keep getting multiple convergence iterations on some load steps.
XX U-P ELEMENTS DO NOT SATISFY THE VOLUMETRIC COMPATIBILITY
Is there anything I can do here aside from just stepping the load smaller? Small load steps work...
Hi all you expert Ansys users,
I was hoping to get some feedback on one of my models that I am running. I have a working model, and I am confident in the results. However, I have many models to run and the run times are quite long (in my opinion). I was looking for some thoughts, comments...
Hi all,
I am running an analysis and I keep getting a warning saying " Pivoting option activated for Sparse Direct Solver. The memory
required may greatly exceed predicted amount. In that event rerun
with increased memory using -m option "
Because of this the solver always...
Hi,
I am currently learning how to use Distributed Ansys as we have upgraded our computing system. However, the biggest issue I seem to have is that I cannot monitor my solution progress. When using the GUI or batch mode, there is no output window like regular Ansys so I have no idea how far...
Hi everyone,
This is basically just to clarify my understanding of the load step. I have a part which undergoes large deformation very quickly with virtually no load. The simulation is a metal cable bending around a large cylinder. The cable starts as tangent to the cylinder then a downward...
Hi,
I am trying to model the contact deformation that occurs when 2 parts mate. I have constructed my 2D model and have created a contact surface between the lines that are going to be making contact. Basically my simulation has a sharp corner (say from a rectagle) hitting the side of another...
Hi,
I was wondering if anyone knew any places to get raw data for standard materials. For example, I am trying to investigate contact deformation of Steel 4340 (standard material) but the stresses get way to high for the linear models that Ansys accepts. I have used the TB command before and...
Hello All,
I am going to be modeling some rubber parts in Ansys for compression testing. I have no experience with these materials, and am completely unfamiliar with what material models to use. The material will be natural rubber. I appreciate any guidance. Also, even more helpful would be...
Hi,
I want to model a material (tool steel) during compression testing. Is there a way to put in the hardness number into ansys? I have 2 different variations of the same material with the same Modulus, but different hardness numbers. How would one go about that in ansys? I tried to search...
This *should* be a very simple question. I am just animating over results for my part and everything works fine, and I can save it to an AVI file. The only problem is, I cannot view any sort of scale so the animation is almost useless! I tried googling this and looking through my manuals but...
Hello.
I am modeling a 3D part (can only be done in 3D). I am applying a large tensile load which I know will exceed the yield point of the material(AlNiBr). I want to plug in the data points for the stress-strain curve in the mat'l properties as "nonliner multilinear elastic". However, the...
Hello,
I am using Ansys to model some simple plates, and I keep getting a DOF error. I know what it typically means, but for some reason it is connected to my contact area. Let me explain. I have 2 circular plates with holes in the middle. They are stacked one on top of the other. The...
Hello,
For those who read my last thread, I have completely solved it. Thanks to those who helped.
My new quesion is merely conceptual. I have a pressure vessel with an internal pressure that will have only HALF of its external shell subjected to a very high external pressure. I am not...
Hello everyone. This is my first post, so bear with me.
My project involves fitting a solid shaft of Beryllium Copper (BeCu) into a BeCu sleeve. I am trying to figure you the best method to do so. My calculations are a bit rusty so I am not sure if I have done this correctly. I suppose the...
