    Element Deformation Only Error

    I did not work with brick elements. Try first working on a simpler problem by modeling the beam with beam elements, using fixed BC at the supported end while applying that pressure on the free end. There might be an issue with your BC's, or your bolted connection representation in your FE model...

    Obtain cross-section forces

    Hi, Just a little note on obtaining the correct cross section forces: NFORC is the element nodal force output, and gives you the corresponding internal forces at each node representing an element. NFORCSO results are computed at each element integration point and might or might not be accurate...

    Element Deformation Only Error

    Hi, I do not know the details on how you apply that pressure, BC's and how mesh-sensitive your problem is; but your problem might be mesh sensitive. After making sure that you sort out the correct BC's and the distribution of the pressure, check that you have a mesh fine-enough. As a general...

    Warping conditions on beam element in ABAQUS

    You're welcome. I think you might need to read that section of the manual I mentioned in more detail. That warping magnitude "w" is the 7th DOF you might want to play with. Regarding B31OS and B32OS same section of the manual says: "...These elements are meant for the analysis of thin-walled...

    how to calculate equivalent nodal force from body force?

    Here's a more general case when more than one elements are contained on a line-distributed force. See the instructions on the picture I am presenting in attachment.http://files.engineering.com/getfile.aspx?folder=f992358e-bba8-4c87-9def-7a925902ac7b&file=staeqnodal2.JPG

    how to calculate equivalent nodal force from body force?

    Hi, If I got it correct, I think might want to look at the problem of computing the statically equivalent nodal forces from a distributed line-force. In attachment I am providing an example, take a look at...

    Warping conditions on beam element in ABAQUS

    I do not know which specific problem you are working on, but another alternative could be using shell elements to model the beam. Just sketch the cross section as shell and extrude it. Then you can use S4 elements to mesh the part which are quite good at modeling bending behavior. Once you...

    Warping conditions on beam element in ABAQUS

    I think your question is addressed in ABAQUS Analysis User's Manual, 29.3.3 Choosing a beam element. There you can read the section about Warping (open-section) beams. "...Element types B31OS, B32OS (and their “hybrid” equivalents) have the warping magnitude, w, as a degree of freedom at each...

    partitioning or selecting faces in ABAQUS using scripting techniques

    Hi everyone, I am trying to automate the process of creating models in ABAQUS using pure python scripting techniques. Even though I found a few resources on the web for specific but relatively easy geometry examples, I could not get how to use *faces.findAt to choose the faces I would like to...
