    Damping in Abaqus/Explicit

    I am using filters to some extent, although I would like to eliminate this noise. (or atleast have some way to prove that damping would remove the numerical noise before using filters). I am measuring some velocity and I have a noise of about 300 Hz in the output.

    Damping in Abaqus/Explicit

    I have some noise in my Abaqus Explicit Simulation, would like to use global damping. I have found only Bulk Viscosity for Abaqus Explicit. Although I would like to use Mass Proportional Damping, but I dont think, there are options for the same. Mass Proportional Damping is available only at...

    ABAQUS RIGID PART VS RIGID SHELLS

    Any advice on how to go about it.. As in to use shells or surface elements ? And How much performance improvement will be there, from converting rigid part to rigid shell ? Thanks in advance.

    ABAQUS RIGID PART VS RIGID SHELLS

    I am simulating some assembly, where I have found out that, converting deformable parts to rigid parts have no effect(negligible) to the results I want to extract. I wanted to know, if rather converting deformable parts to rigid body, I can convert them also to rigid shell or surface and...

    Transfering angular Degree of Freedom between parts in ABAQUS

    Would the MPC beam rotate at the point where they are joined ? I was thinking more like a slot connector. Would that work ?

    Transfering angular Degree of Freedom between parts in ABAQUS

    In the below diagram Assume that there are two parts, red part and yellow part. Red part and yellow part are only allowed to rotate around the center of the black circle. These parts are not connected. If I move the yellow part by angle alpha, I want the red part also to move by angle...

    ANSA Meshing a Pre-Meshed Part

    Is it possible to do it in ANSA ?

    ANSA Meshing a Pre-Meshed Part

    Hello, I have a part as a input abaqus meshed file. I do not have the geometry. I am trying to mesh it again, although I believe to create a more custom mesh, I would require CONS and other parameters which are in geometry. Is there any way to make geometry again from the meshed part, or...

    Abaqus/Explicit Contact Pair Warning

    Thank you for your response. I am using "Abaqus 3DEXPERIENCE R2019x HotFix 18" . General Contact is giving very weird results (this I am trying to figure out). In the meantime I would like to know what could be the problem for the above Warning.

    Abaqus/Explicit Contact Pair Warning

    I have the following Warning, ***WARNING: A shell surface with shell offsets has either rigid elements or deformable elements made rigid. Rigid surfaces with shell offsets cannot be used with contact pairs. The shell offsets will not be enforced within the...
