Userhyper routine in Ansys v.11

[felipestumpf]

Hi everyone

I´m using Ansys v.11.0 and I´m trying to use my own hyperelastic law through Fortran sub-routines. I´ve written my sub-routine and I´m absolutely sure it´s correct.
My problem begins at the compiling process. According to Ansys Manual, what I have to do is write my sub-routine and put my Userhyper.f file into "intel" folder where ansys was installed.
Then I have to, through ANS_ADMIN utility, Relink Ansys and an ansys.exe file will be created. That´s where my problem begins. No ansys.exe file is created and more, after doing this "relinkage" I have two Fatal errors:
"fatal error LNK1181: cannot open input file "htmlhelp.lib""
"fatal error U1077: 'link' : return code '0x49D' "

and as I said, no ansys.exe file is created.

Reading other foruns around the internet I´ve found some who have tried to copy ANSCUS.BAT and MAKEFILE together with the sub-routine file Userhyper.f files to the working directory and run that BAT file there, but all I get is an empty f_comp.log file with 0 bytes and no ansys.exe is created as well.
I´m pretty lost about this issue and I hope you could help me out with it.
By the way, I have Compaq Visual Fortran 6.0. Do I have to compile userhyper.f before relinking? Can I do this with this version of CVF?
Thank you very much

I forgot to ask if is this easier to do in ANSYS or ABAQUS.
Do someone have experience in doing that?

thank you very much

It sounds like you are on the right track, I am not sure why it did not work for you, although I have to admit that I don't use Ansys that often anymore.

Any Ansys manager who wants to sponsor me with a copy of the latest version of the software ;)

It is quite easy to write a user subroutine for a hyperelastic material in Abaqus. I can walk you though that if you want.

Thank you very much, Professor.
I think I´ll end up moving from Ansys to Abaqus anyway, since I couldn´t get any solution from anybody about this issue. Searching in other Foruns it seems lots of people have the same problem and nobody knows how to get that right.
Once I start trying it on Abaqus I contact you back.
Thanks again.
