I have seen that various researchers have asked the question and i tried the answers provided but still no luck.
Dear Kartikeya,
I do not know how it is in Abaqus, but I see the same Problem sometimes in Ansys, too. There, 3D elements are created at meshing with a Jacobian Ratio < 0, i.e. they are some kind of inside-out. (You should see it when you view at one of the elements in question alone.) Happens when the mesher is not able to create a "good" mesh. If this is true with your mesh (you can check this after meshing), try to get a mesh with all elements having a Jacobian Ratio >0.
The elements distorted issue often happened on Abaqus explicit solver.
1.You can control the mass scaling and limit the max percent chng mass value(sat file).
2.Refine the element size.
Good luck
In my opinion, you should control the contact properties and contact definition conditions. Furthermore, the type of element and the size of it are important parameters.
Hello Kartikeya Dixit,
Convergence problems are frequently encountered. The following trials may improve the situation: changing an initial step value, changing the maximum allowable step value, change contact definition, changing friction coefficients, changing friction law, changing mesh density, changing mesh region, changing solver. For anti-vibration simulation, regular elements should be first considered, e.g. three-dimensional brick elements are superior to tetrahedron elements. T
he above paragraph comes from my book “Numerical prediction & case validation for rubber anti-vibration system”. I have used Abaqus as well. Hope it would help.
I am using hexahedral elements, is that creating the problem? with tetrahedral elements file size in GBs. working with that size is hanging the computer.
hexahedral elements should be good and the other answers have mentioned the quality of the elements you used. Their comments need to be considered.
You should change your models' partition and use of hex-dominated elements for your parts. Also you should change your loading mechanism.
Smita Singh Defining correct boundary and loading conditions as well as material properties helped me in dealing with this error. By correct i mean realistic properties. Hope it helps
If this is an explicit Analysis you should try to set the Precision to: double
