    Can I use Creep test data in Abaqus directly?

    Thank you this was helpful [thumbsup]

    Abaqus job not running?

    You can try to ping the license server. Also, you might have some background jobs still running, which may reduce the available tokens. Check the task manager and If I remember correctly it is SMAstamain. If this is consuming CPU and/or memory without you running the job you might have some...

    Can I use Creep test data in Abaqus directly?

    Hi, This is the first time I am trying to model viscoelastic material. I have creep test data (tensile). I checked the documentation, but I am a little confused with the "shear compliance", and 'shear modulus" terms. I am trying to find if need to request a new type of creep test, or can I use...

    ABAQUS - Student new to software, keep getting error messages when running job - please help!

    You also have a warning. ***WARNING: DISPLACEMENT INCREMENT FOR CONTACT IS TOO BIG. I think this might be the source of your problem. Be sure you are applying the right displacement or the units you are using are consistent.

    Error: Check the disk space on your system, An attempt to access admc buffer has failed

    If you are running a large model you may run out of space during simulation due to abaqus generating temp files. I would first try to simplify the model. If this is not possible try to reduce the frequency on your field and history output data or just request data from your region of interest...

    Extract results from a region of interest Abaqus

    Your nodes must be your upper and lower boundaries. Anything in between those nodes will be within the node boundaries. You may try to interpolate.

    Extract results from a region of interest Abaqus

    I think you need to identify the nodes on your region of interest and you can use this code to extract data session.xyDataListFromField(odb=odb, outputPosition=NODAL, variable=(('S', INTEGRATION_POINT, ((INVARIANT, 'Max. Principal'), )), ), nodeLabels=(('Part-1-1', ('5', '10', '11', '21', )), ))...

    Importing .Stp file

    Well I am not sure what is the issue but if your file is not too large I can try to convert it for you.

    Importing .Stp file

    It is basically the same thing but try right click on part from model tree and select import. Also, you can try the file I attached here. I got it from...

    Abaqus explicit Yield status (output request)

    I was wondering if there is a status output request for yield in abaqus explicit (yielded(1) or not(0)). I use Mises stress to check yield but I just wonder if there are other ways to check it.

    How to determine the optimal number of CPUs for a simulation?

    Before I did not have this problem since I had limited cores. Right now I am able to use up to 512 cpus and I would like to learn if there is a way to optimize the cpu usage or a rule of thumb. Thanks

    How to mesh for crack propagation?

    The meshing problem I had wasn't related to the crack but a different contact problem. So, I did not actually do much crack propagation in 2D models but I did in 3D. Based on my experience, I can say tie constraints change the crack behavior slightly. In my simulations, there were some cases...

    Memmory allocation problem

    I am assuming you have 60 GB of physical memory but for some reason abaqus detects it as 8 GB (based on the documentation). I had a different memory issue for some reason my simulation failed on 416 cpu (26 nodes with 16 cpus and 128 GB memory) but it worked on same cluster with 48 cpus. I only...

    How to mesh for crack propagation?

    I had a similar problem. I was asking myself how on earth did this people do this kind of mesh. So, my solution was to partition the region of interest exactly as you see in the images and mesh it with single element. With this you should be able to duplicate the mesh. I would also suggest you...
