Hi Dave, I re-open this thread because I need to ask you a question. If I'm not interested in using the FEA simulation to optimize the stent geometry but only to verify the fitting between the stent and artery it is necessary however that I use Hex Elements instead of tet elements? Thanks Luca

Hello everyone, I am new to the world FEM Abaqus and I need your help. In the compnay where I work we deal with FEM simulations in the biomedical field. We need to evaluate the acquisition of Abaqus and I was asked to think of a workstation (computer) performing and suitable to perform FEM...

Hi IceBreakerSours, I use Rhinoceros that has a function to convert mesh to NURBS but what you get is a gross surface approximated by triangles and not a single compact surface. Practically this is a Reverse Engeneering process that would be very complex and long to do by hand. I haven't...

Thank you. What you're proposing is really useful to me. I'm trying to draw my cell stent in 2D and then apply mesh in Abaqus and wrap it around the cylinder with the NMAP command. I have another problem though. My stent addition to opening should also go to "bump" against the vein that, in my...

Thanks for your reply. If I understand you correctly you are suggesting me to design my stent in 2D with an external software (I use Rhinoceros and I have to continue using this software, I can not draw directly into Abaqus). Then I can export the 2D model of stent In Abaqus (.stp file?) and...

Yes, but when I try to assign Hex mesh this message appears

Perfect thanks. Are you suggesting me to reduce the size of the mesh to make it more compliant expansion of the stent? During meshing I entered values for reduce calculation times ... but I'd have to see them again ... How can I measure diameter of final expansion compare it with the initial...

Hi, I have solved the above problems and I'm able to successfully carry out the simulation. I'm studying a lot of literature to try to understand the physical and mechanical problems that exist behind the simulations and I'm learning a lot. However in publications rarely explains the process...

Thanks for your reply. I'm trying to develop BCs but when I submit project to analysis Abaqus give me this error: 3500elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection I noticed that there are many similar mistakes written on this...

Hello everyone, I am a researcher in the field of biomedical 3D printing and I need your help on a Abaqus software. I am a new user of this software, and I would like to ask questions to you who are more experienced than me. I should achieve an opening simulation of a stent (medical device)...
