    aborted with system error code 5

    I am getting this error message. I don't know what it means "aborted with system error code 5"

    Connectors attched to deformable body

    I have a 3D deformable body that is being pulled with linear connectors attched to the other end. As the body is pulled there are stress concentrations at the location of teh connectors to the deformable body. Does anyone have a suggestion or a way to apply to connectors with out getting the...

    multiple loads on rigid body

    How do I assign multiple concentrated loads at different locations on a rigid body? I can assign a sinlge load at a reference point but iwant to apply multiple loads.

    transversley iostropic

    I have a semi circular solid that I want to define trans. isotropic material properties. I defined material orientaions but how do you get the material orientaions to follow the curve of the semi-circle?

    Viscoelastic properties

    I am trying to run a viscoelastic model. Is there a method that allows for tranversely isotrpoic viscoelastic material properties. I am able to run isotropic elastic but I cannot run the trans. iso. viscoelastic

    Meshing problems

    I am importing parts and I want to use poroelastic conditions but the problem is too big to run with quadratic elements. I can not select linear elements though. Is there a setting where I can run the contact problem with linear elements?

    VOL FLUX error

    I get the following warning in a contact problem with two poroelastic deformable bodies: "There is zero VOL. FLUX everywhere in the model based on the default criterion. please check the value of the average VOL. FLUX during the current iteration to verify that the VOL. FLUX is small enough to...

    nodes may have incorrect normal definitions

    I am getting this warning, "nodes may have incorrect normal definitions" and I do not understand how to fix it. From the manual, it suggests that it has something to do with how I define my contact surfaces but I do not understand how to redefine my contact surface to fix the error

    nonlinear spring elements

    In order to prestrain a nonlinear spring elements I defined a nonlinear-elastic connector with the force-displacement curve, then I entered the zero load length with the reference length option. Is this the correct method to do this?

    permeability

    I am modeling a poroelastic material. My k is in mm^4*N^-1*s^-1. The input into ABAQUS needs to be in LT^-1. What are the conversion factors?

    amplitude adjustment

    I am doing a contact analysis. I have a beam with a fixed bottom and I give it a uniform diplacement on top. I apply the disp. as a ramp over the step and it works fine. I apply an amplitude to the displacemnt to perform a stress relaxation analysis, however, when I run the program with the...

    Applying material properties with respect to cylindrical coordinates

    I have an object where i want to assign the material properties with respect to the radial, circumfrential and axial direction. I assigned a material orientaion to the part but I do not know how to assign the material propeties to correspond to the datum refernecs I created. Will assigning a...

    Insering a datum point of a face

    I tried a few methods but is there any way to insert a datum point of a curved surface 9in order to attach a spring to that surface. i tried projecting onto teh surface but the surface is very irregular and the datum point does not project where I need it to

    Initial Conditions, void ratio

    I am perfroming a contact analysis with a porous material and I get a error that reads "Permeability is specified on 20 elements but the initial void ratio is not defined. Use *initial conditions to the value. The elements are identified in element set ErrElemPermNoInitVoidRatio." I have tried...

    Porous Elastic Material

    I have read the manual about poroelastic material for Abaqus. However, I was wondering if there are any tutorials that anybody could recommend to understand the material constants needed for input for poroelastic material, espcially for biomechanical applications.

    Solid part assembly

    I have multiple parts I have imported into ABAQUS for assembly. However, the parts are in different model and I cannot import theminto the same model. How do I do this?
