subroutine

Dear Community,

I make a code public for bone remodeling, using the Komarova model. It was developed by me alone. I provide the code as is, without warranty.

The agreement between my data and the ones from a reference are very good for fixed loading, but deviate for a more intricate loading. Lacking access to Abaqus with a Fortran compiler, I am at present unable to pinpoint the cause for the discrepancy between my data and data from the reference. The code can serve as a starting point and I give directions how to identify the cause for that discrepancy.

Dear Mechanicians,

time and again the question of modeling moving heat sources pops up, often in the context of laser heating.

One can achieve this using the subroutine DFLUX in ABAQUS.

I decided to post some links here to avoid responding with a longer explanation to every individual seeking assistance.

Please note that I have never worked with any one of these codes and have no access to ABAQUS at present.

No warranty is given by me.

Dear Mechanicians,

time and again the question of SMA (shape memory alloy) modeling pops up.

In ABAQUS, you can achieve this only by (V)UMAT coding or by using the little-known built-in SMA model.

In the past I have frequently responded to queries on SMA modeling and could refer to a customer help site of SIMULIA. That site is down, regrettably.

I decided to post the files here to avoid responding with a longer explanation to every individual seeking assistance and uploading the files as E-mail attachment every time.

Hello All,

I am required to incorporate the simplest form of constitutive law - elasto-plastic material with power law isotropic hardening in ABAQUS. 

Does any one know where to look for tutorials on writing UHARD in ABAQUS?

Any help would be appreciated.

Thanks,

Jay Patel

Hi there,

Recently I had lots of problem with linking ABAQUS and Fortran compiler together. I did all of the things which has been described in forums but none of them worked for me. Finally I found the solution.

I'm using ABAQUS 6.12-3, Visual Studio 2012 Professional and Intel Composer XE Suites 2013. For linking them simply follow these steps:

1- find the file ifortvars.bat and its path.

In CAE, we can apply the concretrated force on a picked node. However, if we want to use 
subroutine  to difine a complicated force, such as moving load, then we must refer to the COORDS of a point. Because we can use the COORDS of integration points other than nodes, then how to transfer the  node load to the integration points load? Any information will be appreciated.

User subroutine interface

Hi everyone

 I did so much efforts but  I could not reach a successful link
between abaqus 6.10 and Intel fortran 11 and in abaqus verification it didn't
pass.  Is there any obvious way to solve this problem? I have not find any
suitable solution in the internet :(

Regards,

Eddie

Dear all

I need help in executing ANSYS user programmable feature (UPF), specifically subroutine userpr (changing element pressure information) for my 2D model. I have read the manual but don't understand the subroutine program structure (attached below). Can someone kindly explain how can I activate and run the subroutine?

Thanks,
Samuel
