Re: Follow up on GEBT and PostGEBT Downloads

[Qi Wang]

Hi Steven,

GEBT is using linear solver from HSL library. We are not allowed to distribute the solver files, although they are free for personal use. Therefore the users need to download and compile two files using gfortran. Here are the steps:

1. Download and install gfortran (compiler);
2. Download MA28 and MC19 from HSL website;
3. Compile them into MA28.dll. Copy this file (MA28.dll) to the same folder "gebt.exe";
4. Run gebt;
5. Run PostGEBT to visualize the results.

I wrote a step-by-step tutorial for making MA28.dll and running GEBT. Attached please find the pdf file of the tutorial. If you have any questions on installing/running GEBT/PostGEBT, please feel free letting me know.

Hi Qi,

 

No, I have not downloaded gfortran, do I need to, and where from? I am running Windows 7 enterprise on a 64-Bit  OS.

Hi Steven,

 

Have you installed gfortran on your computer? We need this to compile the fortran source code you downloaded from analyswift. Moreover, what is the OS (operation system) on your computer?

Hi Qi,

 

I downloaded the file and the libgfortran-3.dll, but I now get this error:

Hi Steven,

 

It seems like a complier error. This dll file can be downloaded from:

 

http://www.dll-files.com/dllindex/dll-files.shtml?libgcc_s_dw2-1

 

Or you can use the one attached (I downloaded from the above link). Please put this dll file in the folder containing GEBT.exe.

 

Best Regards,

 

Qi

Dear Steven,

 

Thank you for your email and question about GEBT.  Unfortunately, it is not a program that we actively support.  However, it is an open source program and the best option for addressing these types of issues is through the Google group HiFi-Comp (http://groups.google.com/group/hifi-comp), which is administered by Dr. Wenbin Yu, the developer of GEBT.  Dr. Qi Wang, developer of PostGEBT, is also a member of the group.

 

Please let me know when you are interested in trying VABS or SwiftComp Micromechanics (VAMUCH) and I can request some basic export information and send you the correct version.

 

Thanks,

Allan

HI Allan,

 

I am interested in using your products, but am not sure how. The GEBT software I installed gives me this error when I open it:

 

 

How do I fix this?

Dear Steven,

 

Thank you for your time and for downloading the GEBT software.  I hope you have found it helpful.  Are you interested in also trying the VABS software?  

 

VABS is the companion code for GEBT.  For effective design space explorations, one needs to simplify the original nonlinear three-dimensional (3D) analysis of slender structures into a two-dimensional (2D) cross-sectional analysis and a one-dimensional (1D) nonlinear beam analysis. This has been achieved using VABS along with GEBT. VABS takes a finite element mesh of the cross-section including all the details of geometry and material as inputs to calculate the sectional properties including structural and inertial properties. These properties are needed for GEBT to predict the global behavior of the slender structure. The 3D pointwise displacement/strain/stress distribution within the structure can also be recovered by providing outputs from GEBT into VABS.

I've attached a brochure for VABS, presentation and also a publication relating to the tool that has been used for design/analysis of slender structures, (we also have publications related to wind turbine blades, helicopter blades, and other structures).  Please let me know if you want to get a trial license to VABS, and I will request some basic export information in order to send it.
