The paper you cite should be the reference.  The element was originally a user element and all that I did was to adapt as an option under the elements included in frame3d.f

General questions / Reference paper for framf3e.f file

« Last post by huxiang_shi on March 04, 2025, 05:24:40 PM »

Dear Professors,
I am recently studying beam element to employ it, and I found the element framf3e in FEAP, and I am curious that if there is a reference paper about it like other element, I found a paper written by Simo, Tarnow, and Doblare, which named "Non-linear dynamics of three-dimensional rods : Exact energy and momentum conserving algorithms", I do not konw if it is correct, since the last modification record said that "!       Modified to standard FEAP element !       R. Taylor                  -     January 1997", I am a little confused. Can you spare some time to have a look, thanks.

Best wishes
Huxiang Shi

Dear Prof. Taylor,
I really appreciate your interest and thank you for your precious support. However, we have introduced some changes and the code is currently working with this specific model. So, at the moment, there is no need to share the input file, as it is really complicated.

Thank you so much for your precious help
Best regards

I have now upgraded Linux Mint 21.3 Cinnamon to version 22 after which it compiles feappv-5.1.2e without errors to an executable feappv. I leave the problem with that.

I have now installed the latest version of Linux Mint,  Cinnamon 22.2, on a spare computer.
After installing libx11-dev, the compilation of feappv-5.1.2e was successful, no errors but a lot of warnings,
It created an executable feappv.

I will upgrade my Mint 21.3 to 22.2 to see if the problem disappears but I have not had any problems with Mint 21.3 except this with fmt_long. And upgrading is a bit risky so I am not in a hurry to do that.

Thanks for your efforts!

Yours sincerely

Something seems to be deeply scrambled with your system.  If iofile2.h is in the include directory, then you should never have received the message that it could not be found.  I will have to think more about how you can debug this issue.

I placed it  in the include directory:
bjorn@bjorn-ThinkCentre-M82:~/Feappv/feappv-5.1.2e/include$ ls -l  iofile.h iofile2.h
-rwxr-xr-x 1 bjorn bjorn 76 Feb 20 22:40 iofile2.h
-rwxr-xr-x 1 bjorn bjorn 61 Feb 20 22:40 iofile.h


bjorn@bjorn-ThinkCentre-M82:~/Feappv/feappv-5.1.2e/include$ cat  iofile.h iofile2.h

      integer         ior,iow
      common /iofile/ ior,iow

      logical         keepfl,fmtlong
      common /iofile2/ keepfl,fmtlong

So I can't understand why iofile2.h can not be opened.

I was skeptical to having two different common blocks with the same name (I have never seen it before).
So I wrote a tiny program test.f  which made include of the original iofile.h,
compiled and run it all it worked fine:
bjorn@bjorn-ThinkCentre-M82:~/Feappv/iofile$ cat iofile.h test.f

      integer         ior,iow
      common /iofile/ ior,iow

      logical         keepfl,fmt_long
      common /iofile/ keepfl,fmt_long

      include "iofile.h"
      iow = 6
      ior = 5
      keepfl = .true.
      fmt_long = .false.
      write(6,*)'ior,iow ',ior,iow
      write(6,*)'keepfl,fmt_long ',keepfl,fmt_long
      end
     
bjorn@bjorn-ThinkCentre-M82:~/Feappv/iofile$ gfortran -o test test.f

bjorn@bjorn-ThinkCentre-M82:~/Feappv/iofile$ ./test
 ior,iow            5           6
 keepfl,fmt_long  T F

Where did you place iofile2.h? In what folder?
