ansys or abaqus,which of them is better?

 

Hi every one

I am doing my master in civil engineering at U.K.M. University in Malaysia. I want to learn 1 FEM software. But I don’t no which of them is better for me ,ansys or abaqus?. My thesis is about concrete filled tubular.

I must model concrete and steel, and I think I face contact problem to define connection between concrete and steel.

Acccording to my knowlage, the Abaqus may be more better than the Ansys in the contact simulation.

Dear Scholars, 

I am a graduate student of structural engineering. I need tutorial materials on finite element of reinforced concrete (RC) and prestressed concrete (PC) using ANSYS software. I am to work on the static and modal analyses  of the structural elements. Both the GUI and the command type will be greatly appreciated. I am relatively new in ANSYS and it's the software available to me.

 Thank you.

i am master student in civil engineering at UiTM, University in Malaysia. Now, i,m to work my thesis on FE method by Using ABAQUS/CAE on copmosite material (RC beams) . i have a few problems regarding my modelling:

1.  i have a problem to model the reinforcement in concrete, in others word i have a problem in order to model RC beams.

2. i must model concrete and CFRP sheet, and I think I face contact problem to define connection between concrete and CFRP.

According to my knowlage, the Abaqus is more better than the Ansys in the nonlinear simulation. 

Ansys is so powerfull also ABAQUS but the capability of the first one is less than the second in visualiziation and in output layout ABAQUS is more sophisticated deal with sophisticated problem with large element data base, Ansys is easy to learing. For example i was write a paper on who to model a Tire in ABAQUS and ANSYS the resluts after solution make me sure that ABAQUS is more powerfull in output make the Tire moving on surface of plate,also the ABAQUS when i was reading on it capability i saw that ABAQUS is able to simulate the Chips in cutting and able to mesh regenerating

I like ABAQUS very much!In my opinions, the ABAQUS is better than the ANSYS in the nonlinear simulation. 

The ADINA System offers a one-system program for comprehensive finite element analyses of structures, fluids, thermal, fluid-structure interaction and thermo-mechanical coupling.

With the ADINA System, there is no need to use one finite element program for linear static and dynamic structural analysis, another program for nonlinear structural analysis, and yet another finite volume based program for fluid flow analysis. Furthermore, the ADINA System is the leading program for fully coupled analysis of fluid flow with structural interactions (multiphysics).

For more information you may visit ADINA R&D INC(http://adina.com). If you are based in South-East Asia, you may contact Ning Research (http://ningresearch.sg/) for a trial license.

Hrllo,

      My name is Ravi Merchant, i am doing an project on modal analysis of small components for my graduation project, can anyone suggest me the software which i can use for my work. please suggest one of the following. 1 ABAQUS or 2 ANSYS.

      I would be eagerly waiting for your reply

                                                                          Warm Regards,

                                                                                 Ravi.

I am a new learner for ANSYS for my post-graduate degree on welding field.

Could you give me some advice?

Hi

I am working on the nonlinear inelastic
analyse analysis of concrete-filled steel tubular (CFST) short and slender
columns under axial loading. I have material properties for steel and concrete.

 For short CFST
columns, the columns are fixed at the bottom. The static load are applied at top.
My question is:

How do I use the
modified RIKS method to apply the load? How do I use deflection control method?
How do I obtain axial load-strain curve?

Best regards,

Vipul Patel

According to my understanding, iMechanica has mostly scholar members. So, most of you people are associated with a university (mostly grad. students or post-docs). Therefore, it's really strange for some to ask such a question "Which FEA package is better?". At least you people are expected to have a knowledge of FEA, and the I think this question is out of the box which one is better. Do you guys live on the mercy of FEA package or the FEA theories. If you work with package only, then your  asnwer is quite understandable. And if you claim that you have some understanding of FEA, then your first response should be, "It depends what you want to do. For most of the problem, Abaqus/Ansys/NASTRAN/ADINA/Ls-Dyna/SAP2000/etc... will give you same result, if the problem modeled correctly".

The reason I am being so impolite is becase it's a regular norm to ask such FOOLISH question (I've seen many such questions on several forums). The beauty lies in the eyes of beholder, and the same holds true for FEA packages as well. And as per his problem, both will give same result. Although I am abaqus user (and I love it), I do not favor it and start saying it's better or worse than some other code. It has its own limitations and bugs as many other codes.

For most of the problem, if any package offers some functionality, then most of the time it's user's mistake and not the packages limitation. Ansys will do the job for him in the very same way as abaqus would do. So, in my view, you guys shouldn't misguide some newcomer because you favor the package. Always remember, "IF DONE CORRECTLY, ALL FEA PACKAGE WILL GIVE SAME RESULT"

Abhimanyu,

If your statement "IF DONE CORRECTLY, ALL FEA PACKAGES WILL GIVE SAME RESULT" is accurate and is the primary consideration in choosing a package, the answer to the original question is "choose the package that costs the least."  I think the original poster was asking a slightly different question but hadn't really thought it through to formulate the question precisely enough.  The question is a valid one and requires serious study to answer accurately. 

I use Ansys, Abaqus, LS-Dyna and Comsol on a regular basis. Yet, my answer to the original poster would be "I don't really know.  What types of problems do you want to solve?".

Biswajit,

I completely agree with you. That's exactly the point. Unless the purpose or the type of problem is unknown, how can we bias ourselves towards one FE package. For most of the general analyses, all codes will give same results. And, if two codes provide nearly similar functionality (e.g. Abaqus and Ansys), the results obtained should remain same. This is what I meant by "if done correctly, all package would give same result". 

So without knowing the details of one's requirement, recommendation of any package would be just personal bias (and will not be justice to FEA). 

What I perceived from the originator's question is that he wants to learn some standard FE package that will not only help him his MS research  but also in future. If that case, use whatever is available to one. I have seen people forgetting about the FEA basics, and relying more and more on FE package. And, this is the reason, I wrote so harsh reply. In my view, one shouldn't live on the mercy of a package, rather use it to serve oneself.
