Hi, I want to expand a stent to a certain diameter by using a pressure load that increases until this required diameter is reached. Is this possible in Abaqus/Standard? At the moment I am using connectors that prevent the stent from expanding beyond a specified maximum diameter, and so I need...

Hi, I am using Autodesk Inventor 2011 to create parts for use in Abaqus 6.8. I split my model into 2 parts in Inventor and then merge them into 1 part in Abaqus as in its one part configuration the model cannot be meshed by Abaqus, but by merging them this gave me a boundary between the 2 which...

Hi, Is it possible to retain the boundary of a created feature (e.g. a sweep) feature onto an existing feature (revolve). I am using Inventor 2011.

Hi I am currently working on convergence plots to determine the appropriate mesh density for a model with two part instances. I am plotting quantities such as ALLSE and ALLIE at specific time points to determine mesh convergence, but at the moment I can only output these quantities for the whole...

Hi Abaqus crashed and when i try to open the model database now all I get is a message "Rfm_StringManagerFile::String – String is not available.". Is there anyway to "repair" or open the model database?

Hi I am trying to convert an orphan mesh part to a geometric part. I have tried in Abaqus but I don't think it is possible. I am using CUBIT 12.0 to remesh the mesh part in question but it also is unable to create a geometric part. Does anyone know of any software that is capable of doing this?

Hi is it possible to request the distance between too nodes at a specific time in an Abaqus/Standard analysis thanks

Hi, I am using automatic stabilization in a static, general analysis step for a model involving contact. I am using the specify the dissipated energy fraction method with adaptive stabilization set to 0.05. From reading the manuals I reduced the dissipated energy fraction until the ratio of...

Hi I want to apply a connector with a "stop" behaviour to a part with approximately 6000 nodes. Is there a quick way of repeating this process or can it all be done at once using a set. One point of the connector is connected to ground

Hi, I am expanding an open ended cylinder (shell) with pressure loading inside a deformable curved tube (solid). I want to constrain the cylinder so that its centre line (at the midpoint of the cylinder) will coincide with the centre line of the curved tube throughout the analysis. I think this...

Hi I'm trying to model the inflation of a simple model of an angioplasty balloon consisting of a straight cylinder with tapered ends to about 4 times the original diameter of the cylinder however I cannot get many of my models to converge and for any that do converge the resulting increase in...

Hi, i am trying to expand and deflate a cylinder (modelled as a shell) within a deformable curved tube. I am expanding and deflating the cylinder using displacement boundary conditions and a cylindrical csys. The analysis works fine except for the balloon which returns to its initial position...
