    ABAQUS error

    I think you put 0 stress for a nonzero plastic strain. I would guess that the first column is the strain in your data.

    Using only substructures

    Thank you for the quick response!

    Using only substructures

    Hello, Is it possible to create a model only using one or more substructures (no other mesh elements)? Example: Create a substructure of a beam and retain 6 DOF for each end. Create a cantilever setup with the substructure in an implicit static step. One substrucure, one boundary condition...

    getScalarField at middle of shell element thickness

    I tried adding the following: sCat = odb.SectionCategory(name='SC',description='n/a') sP = sCat.SectionPoint(number=3,description='n/a') together with the addition .getSubset(.... , sectionPoint=sP) The code did not return any error but didn't produce any field output. I managed to work...

    getScalarField at middle of shell element thickness

    I have read about addData(...) optional argument sectionPoint. I am however not able to get that part working. Where do I write the addData and what is the value the sectionPoint argument accept? addData(sectionPoint=3)? Best regards, S

    getScalarField at middle of shell element thickness

    Hi, I am working on a script that creates a field output in an odb. The odb contains an element set with shell elements (5 section points, S4). The code I am using to get the scalar field looks like this: stress = frame.fieldOutputs['S'] inPlaneMaxPrincipal =...

    Abaqus for structural analysis

    Is it something like this you are looking for? Link

    High Velocity Impact

    I believe that a set of internal element faces need to be added to the general contact for it to keep making contact. Included pairs of general contact: All* with Self AND All* with ElementInternalSurfaces

    Mass density

    Hi, I think it should be tonne/mm^3. Could 7.6982E-09 tonne/mm^3 be correct? If the model is fast to solve you could always check the reaction force and compare to expected reaction force.

    Remove entities

    How about cut extrude some material away and then extrude it back up?

    Wall clock times lower for cpu only versus cpu+gpu simulation

    Hello donaldhume, What I mean is that most modern Nvidia cards allow for gpu acceleration. Consumer grade (e.g. GTX1080Ti) will not allow to be used with Abaqus I think. It is not a professional card. Quadro cards are professinal cards and can be used for GPU acceleration. Nvidia does however...

    Wall clock times lower for cpu only versus cpu+gpu simulation

    The K2200 is not a new card. It is from 2014. For double the price of a K2200 you get the P4000 with better performance (~3x *for certain applications*). Still, I'm not sure that gpu acceleration is really meant to be used with quadro cards (crippled double precision floating point). Link Your...

    Abaqus Parallelization.

    I remember reading about hyperthreading when I got my Intel 2600k for my personal PC back in 2012. If you run an application which scales great (Cinebench) then you got (at that time) about 15% increase in rendering performance. When it comes to implicit analysis, scaling is not perfect. I...

    Abaqus Parallelization.

    Hello, Multiple processors in the context of Abaqus usually mean cpu threads. Lets say you have two physical CPUs with 8 cores each (Intel) with hyperthreading (2 threads per CPU core). That will give you access to 32 threads. It is recommended to disable hyperthreading in BIOS which will give...

    Unrealistic high stress at a few elements

    Could it be an extrapolation issue? It would be interesting to see how an C3D10I would respond.
