The fact is that, debugging the subroutine I see the totaltime different from the steptime. I am using just one step and the .inp implementation is veryfied with a different user subroutine, so totaltime and steptime should be exactly the same (but they are not...)
The value of the total time is around 1e-8 and the value of the steptime is around 1e-55.
I'm a newer of Abaqus. I was trying to compute a simple compression problem using Mohr-Coulomb model. I found the slope of stress-strain curve from the results is double of that defined in the input file. I don't know what's cause it or my understand of the slope is wrong.
Only one 8 node C3D8 element is involved. To simplify the question, let the friction angle be 0, it reduces to a Tresca model actually. The material is defined as:
I want to model post-tensioning tendons embedded with concrete structure. Both ends of tendons are anchored. Can anyone inform me what kind of element most suitable to model the tendons and concrete structure in ABAQUS? I tried solid part for both items, yet as the tendon diameter is very small if compared to the concrete dimension, the resulting number of mesh on the concrete structure is very large.
For those of you looking for FSI simulation on Abaqus platform, recently Simulia has announced the new features in release 6.10, which introduces the capability for performing Computational Fluid Dynamics (CFD) simulation.
So it enables users to perform coupled physics simulations with
Abaqus/Standard and Abaqus/Explicit, such as fluid-structure
interaction between human tissue, a medical device, and fluid flow, more information:
I'm embarking on a project to build a modified copy of a DIY 3D printer. See http://reprap.org/wiki/WebHome to get a rough idea. In my case, I have my own lathe and milling machine, so I can fabricate more substantial components, e.g., by machining aluminum. I also have larger stepper motors, some 3/8" precision rod and linear bearings that I can use.
How can we perform first structural and then thermal analysis in ANSYS (version 12) ? All the examples show the sequence the other way. I can't go for Direct coupled method as the materials are elastic-plastic (plasticity is not supported by direct coupling elements).
I'm using Matlab and mupad in my research .I have managed to plot a few curves using mupad, a powerful symbol computation soft. Since it is theory solution, I want to add the experimental curves to compare the goodness.But i don't how to make the two softwares work cooperated.
I'm mechanical engineer and working as FEA Engineer in GATES. I have
been using ANSYS for 5 years and I want to ask a question about new
version of ANSYS.
I use ANSYS Mechanical 12.1. I connect "geometry" and "setup" to
Mechanical APDL box in "project schematic". Then when I open Mec. APDL, I
can see the cad model (areas, lines, volumes) and FEM (nodes, elements)
but they aren't connected to each other. is there any way to connect
solid model to finite element model?
