Hi everybody, I am working on a simulation of a receptance FRF of a railway (mm/N) and i am facing an issue related to the pinned-pinned mode (1052Hz ca.) of a 36m model. The modeshape should have always the nodes at the sleepers, but what i get is a wavelength slightly different than the...

Thank you for the answer Mustaine3! It's actually a Dynamic/Implicit step. You mean from the static part and the dynamic one? What would be the benefit of making an import of that part? The BC are already applied for the implicit job. Thank you for the cue. Omar

Hi everybody, I really need your help, i really have been struggling with this issue for weeks now. I want to define a rolling condition of a wheelset travelling at 70Km/h on a rail track. I have defined three steps: 1)Static step: contact initiation with an imposed vertical displacement of...

Hi everybody. I'm trying to simulate a rotation (wheel/railway) of a 162K nodes part (actually 3 parts tied together for mesh refining purposes) in a Dynamic/Implicit analysis. The problem is that with defining several distributing couplings with respect to a reference point the simulation gets...

Hi Everybody, I've been trying to run my first ABAQUS Job in my university's cluster; it has installed ABAQUS 6.14-1, while i can use only ABAQUS 6.14-4 in my PC. When i try to run the Job from an .inp file in the cluster's server, i get this error: Traceback (most recent call last): File...

Hi everybody. I've been trying to compute the vertical receptance of a rail in its midspan; after the natural frequency extraction (0-20Hz) i've performed a Steady state modal dynamics with a concentrated vertical force in the point of interest. What i get as vertical displacement is the plot...

Hi everyone. I'm performing a natural frequency extraction of a railway, in order to get its eigenmodes in the range 0-1200Hz. However, while performing the Frequency step needed for the frequency extraction, ABAQUS computes an enormous amount of natural frequencies, ca. 70 for a 2Hz frequency...

Yes, it did but in the files there are no errors messages. It seems like it ends the whole step procedure and then aborts.

Hi everybody, After the step of calculation of eigenvalues for natural frequencies of a quite big model (789178 nodes) up to 1200Hz the job abort and gives me this error message: The executable standard.exe aborted with system error code 529697949. Please check the .dat, .msg, and .sta files...

Hi to everybody. I'm trying to refine the mesh of my train wheelset model (attached figure). The meshing technique used is a classical Advancing front. While in the radial direction the refinement process is straightforward, in the circumferential one i had several issues and i could't find so...

[SOLVED] The issue was due to my Python iteration for the definition of the wire elements; indeed, i used simply the coordinates of the nodes in order to define them and obviously ABAQUS couldn't find them during the input writing. r1 = mdb.models['Model...

I checked the .inp file and it seems like the ABAQUS compile it in the wrong way. The definition of the elements miss the CONN3D2 nodes. *Element, type=CONN3D2 6147, *Connector Section, elset=_PickedSet107752, behavior="Fastening Spring" Axial, In the working simple model the line is as...

Greets to everybody, i'm really new to the ABAQUS software and this is my first topic. For my master thesis project i'm modelling a FE model of a railway track and wheelset in order to perform a parametric analysis of the rail corrugation mechanism. In order to model the fastening system, i've...
