Hi,



I got a simple 2D problem (a rectangular shell, static general, CPS4R element), with 557 nodes, each of them have 2 DOFs (U1 and U2), according to the data file. But when I print out the ELEMENT STIFFNESS MATRIX, for each element it is a 12x12 matrix which means the rotational DOF about z axis is also taken into account. How can I omit this 3rd DOF? Can I?



Thank you.

Hello,

       I am trying to simulate hydraulic damper by SPH method. I have already tried CEL method but didnt work. In SPH method I have following problem,

1. How to define the particle elements to a fluid inside the damper?

2. for defineing particles we need to write in input file so how and what to add in input file?

 Thanks,

I am doing simulation of fiber reinforced composites, for that I have modelled a cubic REV. However , when I am constraining the opposite faces' node displacement sum to be 0 and coupling the nodes in each face in the direction perpendicular to the area, ANSYS is coming out . I have tried this on i7 processor with 8GB RAM system. I am confused if its a RAM problem or a model problem. If there are too many constraints if I apply coupling as well as constraint???

Hello,everybody

 Can somebody help me,I need to do a thermal -fluid-structural analysis in abaqus.I did thermal-structural but alsoi i need to add CFD anylysis of natural convectio

the best way in abaqus..Is it possible to calculate natural convection and buyoancy drivenn flow in abaqus CFD as a coupled problem with thermal-structural analysis

if yes,how? 

Thank you for every idea

Hi, i am going to run my Experiment for tensile testing of different steel samples at different strain rates ofcourse it is Medium strain rate (1*10^-1  - 1*10³ s^-1 ). and my quetion here is how to adjust my strain rates on this machine? is the cross head speed a strain rate?  if that is the case i think the cross head speed of the machine i am going to use is max. 15 mm/s. so  it is very small for my ranges to apply . any one can help me or give me comment on this issue.

I appriciate any help that comes to me.

thank you
