Hello Everyone,

I have a model which I created in the Hypermesh and simulated in Abaqus. I want to perform Adaptive remeshing on my model.

When I am trying to do that in Abaqus CAE, It is giving error that Orphan Mesh are not allowed in remeshing;

I have tried to create Mesh part and also by converting solid mesh in to shell But did not succeed .

Please suggest me some way to achieve my goal.

Thank you in advance. 

When I run an example problem: exa_hydfracture.inp, the job was aborted
due to "User subroutine uporep is missing". I cannot find a subroutine
like that, or can I edit one subroutine by myself? and how to edit it?
Thank you!

Why are quad elements better than tria elements in fem/ cae analysis?

where can I find matlab coding for 1-D, 2-D elasto plastic non linear problem?

Dear All,

I am doing my thesis on crack propagation and vibration analysis of
transmission shaft of a helicopter. I decided the material to be a glass
fiber-reinforced polyester polymer composite. I need to analyze this on
ANSYS. but previously I use Ansys only for monolithic mateials. I need
help how to input the fiber orientation angle, how to mesh and how to
apply the torque. if any one have full tutorial or step by step tutorial
please froward it. my email is ekuba2010 [at] gmail.com. thank you

I carried out simulations to predict the burst pressure of pipes using Abaqus. I applied internal pressure and the pipe actually busted as shown in the attachment. I requested for pressure to be outputted for nodes and elements sets under “force” in the field output request. When I viewed the result, pressure was not outputted for both the node and the element set.
