I do exclude the gap in the contact element keyoptions, but this automatic exclude is not as good as closed manually.
with Automatic exclude, it needs more iteration to solve the same problem.
Hi everyone,
I have an imported mesh and i need to solve a contact problem automatically using batch mode, the problem is closing a relative big penetration or gap automatically increases the calculation time dramatically (2 o 3 times more than close them manually).
for example when i check a...
Hi flash, thank you for your reply.
The video dont help because i use APDL.
I needed to learn the rezoning technique, in the version 13 it is very useful but i didnt used before.
Hello everyone,
I would like to know how to use the rezoning technique in ansys, i have complex mesh and large displacements, and i think that rezoning the mesh after x substeps could help me.
Appreciating your fast reply
Thanks
Hi again flash, thank you for your reply, it is a good idea, but i have a huge 3D mesh with 3 milliones of nodes and it is imposible to be adjusted manually.
I have another question, i start to use ansys 13, in this version there is no real constant for shell 181 or shell 281 and I dont know how...
Hi brain, my question was about the difficult part. ;)
Hi flash, yes i know the material propert actually breast has three tissues and all of them are hyperelastic (rubber-like) material.
Hi brian, thank you for reply, actually i tried to apply -g internal load, maybe it is good for approximation but didn’t give the exact result due to shape deformation and displacement of the center of mass of the studied geometry and for each elements.
Actually i don’t know how to apply...
Hi again, we know the deformed shape of breast under gravity, so we need to solve a backward problem to have a reference state. Could ansys do that? Help needed!
Thanks and best regards
Hi every one,
I am doing a Biomechanics research of female breast cancer, i am using ANSYS 12 to solve my FEM problems.
I have the mesh of deformed breast under itself weight (from a 3D RMI images) and i would like to know if it is possible to get the zero-gravity mesh of that breast. So i...
Admincae, thank you very much for your fast reply, could you please tell me if you use any speed up method to solve your contact problem. When i tried to solve a smaller problem “with less than 1 million of elements”, it is take me about 3 days, by using a good PC (16 GB de ram) y 8 processors...
Hi all,
I have two questions about ansys, anyone can help me?
1- When opening the mesh with a ".ans" file and the mesh is very complex (about 4 million elements) ANSYS takes so much time (over 10 min) for the load. We tried to load it with Abaqus in the same computer and the load is very fast...
