    Ilegal memory reference (Signal 11)

    Hi! I have a problem with a model defined with three steps (two general steps and a Step3 define as a linear perturbation procedure for Eigenvalues and Eigenmodes extraction. The model converges OK during the general steps procedure (base state definition) but in step 3 ABAQUS crashes with the...

    Plastic behaviour.

    Hi! I'm running a model that cointais plastic data in the definitionf of the steel mechanical behavior. The plastic region is defined using a hardening modulus (classical plasticity theory), but I obtain several messages of excessive distortion followed by negative eigenvalue messages when the...

    64 bits plataform.

    Hi!! I bougth a new computer with 2 processors with 64 bits. What i don´t understand are the models that run easily in a 32 bits plataform don´t run in my new computer. The Abaqus report this message: " INCREMENT 1 STARTS. ATTEMPT NUMBER 1, TIME INCREMENT 1.000E-03 ***ERROR: Issue...

    Stabilization in ABAQUS STANDARD

    Hi!! I,m modeling a gasket model with 16 bolt loads. The gasket has a thickness of 0.8mm with hyperelastic behaviour defined for a second order reduced polynomial. The elements that discretize the gasket are hexaedral (linear, reduced integration). Since the material is not near...

    Sticking slave nodes

    Hi! I'm trying to simulate a model of a gasket(hyperelastic) and the aluminium (elastic) cover. The model have 4 bolt loads and 12 contact pairs. I,m running this problem with abaqus standard procedure. I have no problem in estabilishing contact with all the parts, but in a step that increases...

    Zero pivot when processing D.O.F.

    Hello! I'm doing a standard contact simulation divided in two steps, beetween a 3D discret rigid surface and a deformable hyperelastic 3D model. The first step corresponds to the approach and in the second step I Input a vertical force and no boundary conditions for the discrete surface. The...

    Datum cylindrical system axis

    Hello! I am doing some modeling with ABAQUS CAE and I would like to get contour lines of displacements in cylindrical coordinates. How can I get this kind of results? I have introduced a CSYS Datum cylindrical system axis in the property module but I can't obtain the displacement results in a...

    Volumetric test data.

    Hello! I need to adjust a new material (rubberlike) for a abaqus analysis. I already have the compressive data, but now I want to introduce the data for a volumetric test (compression test) in order to calculate the "D" factor. I want to know if I have to introduce the values...
