I recently created a few large models, and tried saving the CAE file. Abaqus has been working for nearly 24 hours to save the CAE file. It is constantly using 1 of my 8 CPUs and 27 GB RAM (out of 32 in total). The resulting CAE file is about 2GB large, which is large but not impossibly large. I...

Hello everybody, I'm trying to calculate the nodal forces in a very simple model with only 8 elements. I have two approaches, and I would expect both to be equivalent, but they aren't. The first method uses the GUI to plot the NFORC1 field output and then goes to Tools > Query > Probe Values...

You are right ESPcomposites. But isn't it true that the quadratic elements should be more accurate, even in this case?

Can anyone explain me how I can detect this volumetric locking in an automatic way?

Dear sdebock, Thanks a lot for your prompt reply. I’m easing hex-dominated elements in both cases. About 70-80% are hex elements, the other 20-30% are wedge elements. The fibre properties are: E1 E2 E3 v12 v13 v23 G12 G13 G23 15 15 230 0.25 0.0163 0.0163 6 13.7 13.7 And the matrix is...

I have a model in which I have very high stress concentrations. The 3D model consists of fibres in a matrix. The entire top surface of the model is displaced by 0.1%. Z-symmetry is applied on the entire bottom surface, except for the middle fibre. This simulates the fact that that fibre is...

Hello Yaston4, let's assume pickedSet is the name of your set. Each set object has a member called 'nodes'. You can call on this using: pickedSet.nodes This gives you a MeshNodeArray. You can loop through all the MeshNode objects in this array and find the displacement of each of those nodes...

When you do this manually in the GUI and then look at the .rpy-file, you don't see any additional line. This makes me suspect it's not possible. As a workaround you could always make a set for the face and manually highlight the set. I don't know whether that's sufficient for your purposes.

Dear Akabarten, I have a similar problem. Your approach is very difficult to automate in Python. Isn't it possible to extract this from the output database with a script? I would be highly surprised if this was impossible. I have spent several days looking for it, but so far came up with...

I have this problem every now and then. I don't work in Linux and I don't open abaqus with that command. I have searched the web, but I haven't found a solution. I gave up searching, because I have a feeling there's no solution.

Dear JayTung, thank you for the quick answer. My nodes are indeed very dense and my points are taken randomly on a circle. Therefore, your explanation seems highly reasonable. I will implement two small changes: -sort the locations of my path (to get a better path) -sort the XYDAta object...

Hey guys, I'm using the XYDAtaFromPath quite often to extract data from my output database. But the amount of points in my path isn't always reflected in the length of my XYData object. For example, when I have a path of 1000 points, I sometimes get a XYData object of 1001 or less than 1000...

You're welcome.

No, it's 100% python script. You can probably leave out the transformation part in your case. I was working with a local and global CSYS which were different.

Hey spintwo, I have done this before. Below you can find a script that works for my output database. You can adjust it to make it work for yours as well. If you have any more questions, don't hesitate to ask. # Import the necessary libraries from Abaqus from Numeric import * from Matrix...

This was very useful. Thank you!

I'm surprised about the multiple processors. If I buy a quad core, will I only be using one of the cores? Or will I be using 4 licenses? Can you please explain this a bit more?

Does a good hard disk (with a high writing speed) really help a lot?

Whenever I'm scripting in Abaqus, I sometimes want to start with a clean sheet. That's mean deleting all variables. Now I just completely restart Abaqus. Is there a more convenient method, like a command to clear everything?

Dear all, I'm about to buy a new computer, with the main purpose of Abaqus calculations. I currently have a 4 GB 32 bit computer. My calculations often require 2Gb or more RAM and that's currently limiting me. Which guidelines do you have for buying a new computer? -64 bit (to allow for more...
