    Abaqus Licensing Usage Summary

    No, couldn't find it there. I used the following command line to specify the output file in the end. abaqus licensing usage -summary path+outputfilename -log path+logfilename

    Abaqus Licensing Usage Summary

    Hi I'm trying to get a license usage summary using the "abaqus licensing usage -summary" command. The return line says that a .csv file has been created but I can't seem to locate it. Does anyone know where the default location for this file will be? Cheers

    Explicit general contact exclude edge to edge contact?

    Hi I was wondering if there's a way to excluded edge to edge contact in a explicit general contact interaction? CAE gives you the option to excluded surface pairs but not edge pairs. I have two beam parts with different section properties (pipe and circular) assembled concentrically. These...

    How to determine material limits from test data

    As mentioned above, the purpose of the tests was to determine the properties of the materials. Specifically, uniaxial stress strain curves and material limits at varying strain rates and temperatures. The materials in question are polyurethane, which do not typically conform to an applicable...

    How to determine material limits from test data

    Hi all Thanks for the advise, very useful. The test is to determine the properties of the materials. I've used a t-distribution to account for the low sample count and calculated the 99% confidence interval. I've taken the lower limit as my UTS.

    How to determine material limits from test data

    Hi I've received uniaxial tension test data for a range of materials. Each material test was repeated either three or five times. I'd like to establish an appropriate UTS limit for each material. At the moment I'm taking the minimum stress at failure from the range of test data -10%. I was...

    Gravity Induced displacement in Abaqus Standard Implicit

    My understanding is that in a static step you wouldn't, unless you have a time dependent variable. I assumed gravity in a standard implicit analysis would work in a similar manner to say creep.

    Gravity Induced displacement in Abaqus Standard Implicit

    Hi I'm trying to model the rest position, due to self-weight, of an assembly of interlocking components around a fixed radius. The fixed radius is defined as contact with a rigid surface. I then intend to apply a tension to the system. I've assembled the interlocking components as close to a...

    Abaqus Aqua Stress Field Output

    Hi I'm using Abaqus Aqua to analyse jacket structures. Currently my .odb files contain no information on stress in the beam elements of the jacket, even though it is selected as a field output request. I've tried both general static stress and implicit dynamic analysis steps with the same...

    Modelling of bicycle suspension

    looks like the viewer scaling is set to a number larger than 1, mentioned above.

    Accessing element set's material assignment through python commands

    Hi I have a script that extracts specific field outputs from predefined element sets in my odb files. I'd like to be able to identify the material assignment of each element set that my script processes. I can't seem to find a method of identifying the element set's material assignment. Would...

    Beam Beam Contact Explicit

    Hi I'm having some problems trying to model beam on beam contact in Abaqus. I've been able to model beam on beam contact in standard by modifying the model keywords to include edge to edge contact formulation. However, the number of beam contacts is resulting in a slow or non converging model...

    Modelling moving mass

    Do you need to model the dynamic response as the slug moves along the pipe length, or just the pipework reaction to the different phases. You could look at creating a MPC subroutine to model a node sliding along a path. You can tie a mass to the node and give it a velocity to model the slug...
