    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...

    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...

    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...

    ABAQUS: How to define adiabatic interfaces in a heat transfer simulation

    Hello, I want to perform a heat transfer calculation of a simple model. Basically I have one Part which contains two concentric disks where the outer disk is split into "chunks" (see picture below, also attached). I have a surface heat flux load applied in the inner face of the inner ring and...

    ABAQUS: Thermal loading application problem

    Hello, I am having some difficulties implementing a 2D thermal analysis in ABAQUS (my experience using this software is close to zero). In particular my query consist on the application of the convection heat transfer coefficient into edges and faces. I have created a simple example to show...

    ABAQUS: Calculating area of a Solid Of Revolution

    Hello, I would like to calculate the area and volume of the solid of revolution obtained by revolving a sketch. I have used the query tool (mass properties) to get such values. The volume is OK but the area is equal to zero. How can this be possible? This is the warning I get from abaqus...

    ABAQUS: Adding an exception if "InstanceFromBooleanCut" operation happens to fail

    Hi, I am trying to add some exceptions to my code when running the "InstanceFromBooleanCut" operation. Basically I am cutting a series of parts and I do not want my script to stop if the operations happens to fail. Say that I have a part called "pr1" (my cutting instance) and I want to use it...

    Creating a surface with a sketch using Abaqus Python

    Hello, My question might sounds rather simple but my knowledge in Abaqus scripting is almost inexistent. I am creating a script to generate a sketch (just a simple closed polygon) and I want to create a surface for that sketch. In CATIA this can be achieved with the "fill command" but I do not...

    XYZ node coordinates to txt file in a particular fashion

    Hi everyone, I have started using Abaqus and Python today so the question might sounds a bit simple for some of you... I am trying to extract the x y z node coordinates of every face in my tet mesh in order to print them out to a txt file. So far I have managed to get the Node's coordinates...
