    Finite element strong and weak form

    Hello, I have a question about strong and weak form. We use weak form in FEM as it contains only first derivative of the displacement function, so we can use displacement functions with C0 continuity. This can help reducing the computation time. However, strain (and in turn stress) should be...

We use weak form in FEM as it contains only first derivative of the displacement function, so we can use displacement functions with C0 continuity. This can help reducing the computation time.

    Abaqus Neo Hooke model with Lame constants

    Hello, I am trying to simulate a neo Hooke model in abaqus but I have only lame's constants to define potential function mu and lambda. I am confused with abaqus terminologies, it needs C10 and D1. After some search I found that lame constant lambda is shear modulus mu and C10 = mu/2 And lame...

    Help in ABAQUS geometry modeling

    Hello IceBreakerSours, thanks for your comments. I am not that beginner for abaqus to read getting started. I know some things, but I am beginner in sense that I do not have extensive abaqus experience. However I can model simple geometries and can do static elastic analysis with ABAQUS/CAE...

    Help in ABAQUS geometry modeling

    Hello, I'm a beginner in ABAQUS and I am modeling a composite cube block with spherical particle and spherical interphase around particle. I can simplify two spheres to two cubes. But problem is I do not know how to model a cube inside a cube. When I assembled three parts, they can get...

    abaqus simulations fatal error 'utl_FileExceptionWrite' and solver exits

    Hello all, I am trying to simulate a polymer composite and running the problem on the cluster. However during almost all analyses I get this error: Abaqus License Manager checked out the following licenses: Abaqus/Foundation checked out 22 tokens. <116 out of 360 licenses remain available>...

    Trial functions in finite element methods

    Hello, I learned finite element methods, and though I am a practicing engineer I like to read different books on FEM. Every time I get new insight or realize something in a nicer way. And yes, sometimes I get new questions that I haven't realized before! Differential (strong) and weak forms...

    How to use multiple GPUs in ABAQUS command line?

    Hello, I am new to abaqus command line and trying to solve massive explicit dynamics and steady dynamics models. I want to use multiple CPUs and GPUs to sole this. I searched on internet and found the syntax as: c:\Temp> abaqus job=Job-1 cpus=16 gpus=1 input=file1.inp double interactive Is...

    Any suggestions or ideas on how to simulate a drop test in abaqus?

    Hello, I am working on a research to simulate a drop test of a package box with ceramic saucer inside. I am not proficient in abaqus so I am looking for some suggestions. Till now, I created a hollow box with 2 mm thickness to represent it as a cardboard box and a disc for a saucer. I have...
