    Abaqus: 2D mesh

    I have a few questions about meshing. Given a 2D polygon (i.e. a profile built by straight lines) of random shape: 1- Is Abaqus smart enough to mesh it without having a node at every vertex ? 2- Does it convert the polygon to a smooth curve? 3- Does Abaqus place constraints as the element...

    How to open a .aba file in ABAQUS ?

    I have an input file that refers to a bunch of .aba files but I am having problems opening them up. Would it possible to open a .aba file directly in abaqus ? thanks!

    script to remove an entire cell of a part automatically in ABAQUS?

    Thanks Cooken, What would be the command for removing all the faces of a particular cell? def sliverVolumes(modelName, pInterName): #Class to keep only cells bigger than a certain minimum value 'paramVol': paramVol=volCell/part_volume_r allCells = pInterName.cells mask_r =...

    script to remove an entire cell of a part automatically in ABAQUS?

    Hi Cooken, I do not think that the boolean operations are an option, at least when it comes to automation. I simply want to delete small sliver volumes like the one below:

    script to remove an entire cell of a part automatically in ABAQUS?

    Hi, I am trying to write an script to remove cells in a part if the cell volume is smaller than a given value. Is there a simple command to delete a cell? This is what I have tried: def sliverVolumes(modelName, pInterName): #Class to keep only cells bigger than a certain minimum value...

    How to pass tags from CATIA to ABAQUS

    I have a model in CATIA with some tags in specific faces. Basically, I want to open up the CATIA model (with the tags) in ABAQUS, check which faces are tagged and apply boundary conditions to these particular faces. The thing is that I do not know how I can pass the tags information from CATIA...

    How to extract sketches from shell part

    I have a 2D shell part containing a number of shell faces. I would like to extract one different sketch for each of the faces in the part. So far I know how to create a single sketch containing all the shell faces information but this is not what I want. I would like to know how to create one...

    ABAQUS: findAt() and the pointOn question

    Hello everyone, This thing is driving me crazy. It is about the findAt() and the pointOn methods. I have a list of edges called pedges. For testing purposes I ask first for a point on a given edge and I get ((925.125, 554.1, 0.0),), then I ask abaqus to find an edge for the same point but then...

    ABAQUS: Command to calculate the area of a face ?

    So, the subject is self-descriptive. How can I calculate the area of a face? What python command should I use? p=mdb.models['Model-1'].parts['Part-0'] pfaces=p.faces area of each face????

    ABAQUS: Programmatically linkingedges to faces in revolve operation and faces in a boolean operation

    Dear all, My question is how to programmatically relate the edges of a single shell face and the faces of the model generated when the shell is revolved. Also I would like to know how to relate the faces of the resultant revolve and the result obtained when the revolve is intersected with...

    Example of DFLUX or HETVAL ABAQUS subroutine

    Hello, This is the first time I have to write a user subroutine in ABAQUS in my life. Can anybody share an example of a DFLUX or HETVAL subroutine c/w the relevant .inp file? Thank you!

    ABAQUS: How to calculate total Heat Loss over a face

    Hi, I am currently performing a thermal steady state analysis in a fin for heat dissipation. The model is basically a cylinder with a Body Heat Flux [W/m3] as a thermal load and a fin attached to the cylinder. The fin has convection applied as an interaction in all its faces. My aim is to...
