In reply to LINKING FORTRAN AND C++ WITH ABAQUS

I am facing the same problem like Rampa had, all the requirements were recognized (including visual studio and fortran compiler), but still can not run user subroutine. Anyone can help?Thank you very much

Questions on VS and Intel Fortran

Tue, 2015-06-30 19:44

In reply to The required Fortran compiler

Hi Kewei, 

I thought you might know the answer to my question. I am trying to run a simulation with Abaqus subroutines. I plan to use Intel Parallel Studio 2015 (both C++ and Fortran compilers included) with Abaqus 6.14. Will I still need to install Visual Studio, since C++ compiler is already included in the Parallel studio? 

Thank you.

In reply to Revisiting pyramid compression to quantify flexoelectricity: A three-dimensional simulation study

*hello,

my question is what did you use as software to simulate your model, is it based on numerical software such as Ansys or you adopt your proper analytical equations?

and thank you

Brad: Umat

Mon, 2015-06-29 16:51

In reply to Sharing ABAQUS UMAT and VUMAT subroutines

In the input file you should have two different user materials with different names. The variable cmname, holds the material name.

In the fortran subroutine file,  your code should approximately look like:

subroutine umat ()

variable declarations

if  cmname .eq. 'matl1. then

---constitutive equation 1

if cmname  .eq. 'matl2 then

--constitutive equation 2

end

I do not remember, the exact syntax. Please read the abaqus manuals for the same.

Best of luck

Brunda

 

Combining two different UMATs.

In reply to Sharing ABAQUS UMAT and VUMAT subroutines

Dear all,

Salaam,

 

I am going to use two different UMATs for my model. The first one defines super-elasticity and the second one defines bone remodeling proces on my model. My question is, how can I combine them and use them simouloltaniously?

Hi,

 

In micro-macro modeling (HOMOGENIZATION) APPROACH, how have you modeled blocks or bricks (which material model have you used)?

 

Thanks a lot!

Thank you prof.

In reply to Re: Commencement speech

Dear Ajit:  Thank you very much for your kind words.  At the commencement, I read this version aloud, adding no more than 20 words.  To help me prepare, the University gave me texts of commencement speeches from previous years.  Each previous speech has between 1000-2200 Chinese characters.  Mine has about 1600 characters.  When I practiced, it took about 8 minutes.

Opportunities go to multi-dimensions

In reply to Speech at the 2015 Commencement of Xian Jiaotong University

Zhigang, thanks for sharing this inspiring talk! It's not long but very direct to the points. Yes, at the age of big data, opportunities go to multi-dimensions; at the age of Internet, solutions to problems come with a form out of people's imagination. A lot of time, we are shocked by new opportunities when they grow to a big shape, but startups give ideas a trial with relatively low cost.

A straight talk!

In reply to Speech at the 2015 Commencement of Xian Jiaotong University

Very nice, and very straight talk to the young students. I remembered that when Prof. Wei Yang gave the welcome speech to all the incoming students at Tsinghua University in 1994, he projected the great opportunities by which China and World will excel. It took one generation to have all to take place.

In reply to Speech at the 2015 Commencement of Xian Jiaotong University

Dear Zhigang,

1. Yes, I agree, "more information is not a problem, but a chance. Internet has created many new ways to use the information." I used Google Translate here. That's yet another fallout of the technological advancement which has occurred over only the last 30 years! (It really is impossible to convey to the present generation the sense of the world in which most didn't have any phone or even radio, let alone a mobile phone with camera, music and whatnot.)

2. I am one of those who appreciate and applaud the fact that China has become not just the world's factory but also itself a great marketplace, though I didn't know that it had already become the biggest market in the world. It came as a surprise. And yes, "Each puzzle is your chance to display talent." Quite true.

3. Just one more remark: Chinese seems to be not just a cryptic language but also a very economic means of expression, may be because it uses a logographic system. (I didn't believe this was a commencement speech. I thought may be it was just an abstract, and so, out of curiosity tried the Google Translate. Of course, you must have expanded on it extemporaneously.)

Anyway, thanks for sharing. As is usual for your writing, it is pretty much direct to the point, and also, expressed in a generally agreeable manner.

Best,

--Ajit
