I want to do a finite element analysis of the braid vessel stent model with the B31 beam element and the explicit solver, and I find that the wires in the analysis are discontinuous. Should I add some constraints or cross-sectional connections?
I set the radial displacement of all the nodes, as usual the stent should be extended, but the result was not, and the lines became independent segments.
I am trying to use iso-geometric elements in LS-Dyna with the keyword *ELEMENT_NURBS_SHELL_PATCH. The job manager terminates without mentioning where the errors are.
Can someone help me with this? A sample .k file using the above keyword will be helpful.
Certain keywords must be used in conjunction with other keywords; forexample, the *ELASTIC and *DENSITY keywords must be used in conjunction with the *MATERIAL keyword. These related keywords must be grouped in a block in the input file; unrelated keywords cannot be specified within this block.
I am implementing a constitutive relation in UMAT subroutine using the commercial software Abaqus. First, I tested the UMAT subroutine with 'one element model' first. Then I tested with comparatively bigger geometry. It worked fine. Now when I am trying to do a models involving contact, i.e. use of the 'Interaction module'. I am getting error of over-constraint warning for 'Split Tension test of concrete cylinder'. The same input file (except the material definition) is running on Abaqus perfectly with Mohr-Coulomb criteria. I can see a reasonable stress and strain contour.
The new version of the code presents an improved and more intuitive
management of the subroutine and an easier use of Job monitor dialogue.

The improved version of NOSA-ITACA is now available at www.nosaitaca.it/software/. A more friendly monitor analysis has been implemented. Bugs related to card creation are now fixed. At www.nosaitaca.it/software/ you can find also some tutorials that will guide you through the use of the code. Enjoy !
I am facing a very strange phenomenon in Abaqus 2019. Setting up a transient consolidation analysis, and despite converging and showing job as complete, no output is written to the job at all. Needless to say, I am requesting standard field output every n=1 steps and the analysis is 10 increments or so. It's quite frustrating to see your mesh disappear when you expect to see nice colors. If this ever happened to you please do share how you went about it.
The last tutorial (Tutorial4) about a non linear static analysis of a masonry church performed by the NOSA-ITACA code, is now available at http://www.nosaitaca.it/software/. We perform the analysis supposing the structure made of two masonry-like materials with zero tensile strength and bounded compressive strength and a linear elastic material.
The sacrum is the most susceptible anatomical site for developing pressure injuries (PIs), including deep tissue injuries, during supine lying. Prophylactic dressings are generally designed to reduce friction, alleviate internal tissue shear loads, manage the microclimate, and overall cushion the soft tissues subjected to sustained deformations under the sacrum.
Join this webinar to learn how Simpleware software enables dynamic inspection and non-destructive evaluation of high-value parts.
The webinar will cover workflows from industrial CT data to models, from quantitative analysis to dimensional measurement, surface deviation, and use of Surface/CAD geometries. Learn how Simpleware software’s unique features enable comprehensive processing of industrial data and export of robust meshes to simulation to study how manufactured components perform against design requirements.
Join this webinar to learn about the Simpleware-CCNY head model which offers a significant resource for anyone wanting to evaluate product designs and simulate how they interact with the head.
The Simpleware-CCNY head model is a highly detailed representation of the head created in Simpleware software from scan data. The City College of New York (CCNY) is the source of the data, which consists of T1 and T2 weighted scans performed on a Siemens Trio TIM 3.0 Tesla scanner.
Join this short webinar to learn about solutions to typical bottlenecks for medical device design, from patient-specific modelling to pre-surgical planning. We will cover the ways in which Simpleware software solves common medical device design challenges, with topics including:
• Brief overview of the key features of Simpleware software
• Benefits of CE-marking and FDA 510(k) clearance in Simpleware software
Join us for this interactive web workshop where we will demonstrate 3D image processing and analysis using Simpleware software. We walk also you through the workflow of building high-quality models for the inspection and non-destructive evaluation of manufactured parts.
NOSA-ITACA is a software product of the Mechanics of Materials and Structures Laboratory of ISTI-CNR, distributed via the http://www.nosaitaca.it/software/ website.
The package includes SALOME v8.3.0, and is available for Ubuntu 14.04 and 16.04.
NOSA-ITACA enables you to conduct both linear and nonlinear static analyses and modal analyses.
NOSA-ITACA can be used to study the static behavior of masonry buildings of historic and architectural interest and model the effectiveness of strengthening operations.
