Good morning! I am new in SAP2000 and I am dealing with the visualization of frame element numbers. Sometimes I can visualize the frame element number (e.g: 67-1,67-2,67-3,110-1,70-4,etc.) as in the first image. However some other random times I can just visualice the frame number (i.e just...

Ok, nice, I see. The Hyperthreading is reccommended to deactivate only because: - It requires more tokens -> more expensive license that is not compensated by the savings in computational time (at least in my case where for an analysis that took 3,8 hours to run with hyperthreading took 4,08...

Thank you very much for your answers, they were very illustrative and clarifying. However, I do not understand yet why it is reccommended to disable Hyperthreading. This is not the first time I read it, I have read it on other posts but havent found a justification for this, just the advice. At...

Good morning to all. I have some doubts regarding some aspects of parallelization. I read some of the posts regarding this topic on the forum but found different/opposite answers. - In Abaqus CAE, what does it mean Use multiple processors? Does that mean number of processors or number of...

Thanks for your reply. Do you mean then that this results are ok? The resonant frequency is for example 223,57 (from the .dat file, calculated in the second step) and the damped natural frequency is 220, 691 (from the graph, calculated in the third step). Damped frequency is a little bit lower...

Hello. I am doing a modal response analysis to one component which is bolted in its upper part. I first do a pretension step to take into account the force of the bolt, then I do *frequency step to obtain the natural frequencies and then I apply a unit sine sweep to obtain the responses. I am...

Hello! I am analysing one component that has pressure insid. The exterior of this component is join to a wall by one rigid link. I am trying to simulate this connection by using connector builder. It works fine, but the results vary depending on which point I select as first connection point...

Good morning to all of you. Please can you suggest me an interaction to simulate the movement in the video? I am trying to do the same and I am using Tie but it doesn't cause the same effect as the intervertebral disc deforms a lot in some places but not in others (see the attached image for an...

Thank you both! Your info has been very useful! :)

Hello! I need to create a material that has to work as an incompressible fluid. I cannot find in the interface the right command to create it. Any help? Thank you!

Hi! Thank you! I have tried some new things. I transformed all the vertebrae into discrete rigid bodies to reduce computational time. I assigned the mass and inertia and defined reference points for each vertebrae. However Abaqus says thta gravity loads are not applied to rigid bodies! ?????? so...

Thank you for your answers! According to the literature this is the movement the cervical spine must have after a 7g acceleration impact: As you can see the impact last around 250 ms. I am using abaqus dynamic explicit. Step time is 0.250 I am using gravity load of 98.1 m/s^2 and no...

Hello Mustaine3! This is the tie constrain I am using: I choose surface to surface discretization method and regardin to the position tolerance value I have chosen computed default (actually I won't know which value to put in the box). I selected the checkbox to adjust the slave surface to...

Thnaks both for your response! The analysis performed is dynamic. I have done it with gravity load and with the boundary condition of acceleration (two diferent jobs) and obtained similar results in both of cases. At this moment I am trying the load "Body Force". In all the cases I have applied...

Hello to all! I am trying to simulate a frontal crash and see the reactions of this to the cervical spine. I have some doubts about how to input the acceleration resulting of the crash in my model. At this moment I am trying two options but it seems they are not working somehow. 1- Input with...

Good morning all and happy new year! I have a problem and I need urgent help! I am trying to simulate a whiplash in the cervical spine. To do that I have submit my model to a force of xxx Newtons (this is to simulate the aceleration) in the top vertebra. After some hour the model aborts with...

Thank you Mustaine3 for the answer. That is exactly what I did. Some elements of two surfaces that must be together intersect each other. I have looked in the users manual and keyword reference but I can't see anything, just how to use that option using the code, but I am using the interface

Hello! I am running an explicit analysis and I have a warning type that says: The elements in the element set WarnElemSurfaceIntersect-Step1 are involved in surface intersections. Refer to the status and message file for further details. In the status file: ***WARNING: 1219 surface...

Hello! I am trying to mesh a part without the distortion control. I have selected C3D4 elements and deactivated the distortion control. However, when I run the case, a warning message like this appears: DISTORTION CONTROL PARAMETER FOR THE *SECTION CONTROLS OPTION IN Abaqus/Standard IS VALID...

IceBreakerSours, I am trying to buy the tests of Panjabi but my university biblary is having some problems to get them and I still dont have them... So acording to you which would be the boundary conditions I would need to apply? How can I fix the whole vertebral body (as you say in a) and at...
