Mimics®14 enables design on anatomical data

Submitted by Mimics on

Mimics 14 comes with a CAD-like functionality, enabling you to design directly on anatomical data. 

 

Leuven, Belgium, October 4, 2010. Materialise NV, the world leader in software for 3D medical image processing, announces the release of Mimics 14. This release integrates ‘digital’ CAD, allowing fast and accurate design of e.g. implants and surgical guides, starting from a patient’s CT or MRI data.

boolean operation

Submitted by avicina on

Hi

I want to model a plate that connected with stiffening beams in ANSYS.

 beams and plates has rigidly connected together, and there were no joints.

for model this, I first make an area and secondly extend this area to make a volume.

then I divide this volume to seperate plate and beams.

this is my question :

what relation exist berween components when they divide from one volume.

I mean suppose we have a volume, then we divide it in to two parts, what relation exist between this two new

ANSYS CODE FOR FATIGUE CRACK PROPAGATION

Submitted by Amit S. Kulkarni. on

Hi all,

     Currently, I am using ANSYS 12.1 for the fatigue crack propagation simulation for the edge crack & center crack plates. It is a mixed mode crack propagation.

 

Can anybody please tell me or guide me how to write the code in the ANSYS using APDL for automatic remeshing around the cracktip when crack propagates to the new position?

 Thanks in advance. :) 

FEM Programming -Adaptive Remeshing Problem Because of Penetration(Figure was attached to illustrate the problem)

Hello,everyone!

I'm programming by myself to do the simulation of forming process. I met the problem below. [img_assist|nid=8910|title=probelm|desc=penetration in adaptive remeshing|link=none|align=left|width=60|height=100]

I used second order triangular elements and h-refinement method in the simulation. When the workpiece(bottom) is remeshed, the new node is inside of the tool(upper). How can i solve the problem?

Any help will be appreciated!

Thanks!

Discrepancy of numerical results from analytical solution for an nonlinear viscoelasticity model

Submitted by aquis_mech on

  I have written a Fortran code for nonlinear viscoelasticity according to the Hughes' recurrence algorithm based on a total Lagrangian formulation.  And a relaxation test is made. There is some deviation from the analytical solution(Theoretically the stress response should be an exponential decay plus a constant, isn't it?). The numerical ultimate stress is larger than the analytical one. As a larger initial strain is applied, the deviation is smaller. For a inital strain of 10%, there is almost no difference between the num. and analy. solution. What can account for this?

pin forces in ANSYS

Submitted by kameshwarang on

hi all,

i am doing static analysis on a pick and carry crane, i need to find the pin forces. for this i created entity set with the nodes where the forces are to be derived and ran a static analysis in ansys.In order to derive the forces , i first picked the entity set and then applied the nodal loads from the list result options. the result that i got was not fine. it states there was zero forces on the pins, but its not.i need to find the pinforces, so kindly let me know , how to do it.

 

thanks

question about abaqus

Submitted by rainy_boy on

Hi guys

I want to simulate a problem with abaqus,but during runing of my project,percent of process not increas for axample when i change mesh sizes to biger runing go up to 50 % and when i change mesh sizes to smaller than the previos size,it occure again but in 25%

is there any one that know about this problem,i'm trying to solve it for 2weeks but i cann't.

I'm waiting for your suggestions...
