software of interest to mechanicians
Hi all!
i got a problem with install franc3d!
i have downloaded cygwin(it is about 1.8Gb) and install it and launched
xwin server.(not from start button. i launched xwin.exe directly)
then i opened cmd.exe and type ./franc3d
but it could not be launched. i encountered with this error: "can not open display"
startxwin.bat is not in mentioned directory. what should i do?
I'm using elastic solid elements to model wave propagation in an
structure in LS-DYNA. I need to add the effect of dissipation in the
system by using viscoelastic material model (MAT_006). All I know from
my material is storage & loss modulus (E=E'+E"*i). I was wondering
how can I transform these parameters into G0, GI and BETA needed by
MAT_006 (G=Gi+(G0-Gi)*exp(-beta*t))?
Dear Colleagues,
At https://sourceforge.net/projects/cmcodes/ you will be able to download open source software for the extended finite element method, the extended element-free Galerkin method and extended isogeometric analysis methods in 2D and 3D.
Some of the papers associated with these pieces of code are here:
hi dears
i have som problems in my project that should be simulated with abaqus .
The
elements contained in element set ErrElemExcessDistortion-Step2 have distorted
excessively.
There
is only one excessively distorted element
The
ratio of deformation speed to wave speed exceeds 1.0000 in at least one
element. This usually indicates an error with the model definition. Additional
diagnostic information may be found in the message file.
Hi Everyone.
Can anybody please expalin me what is the meaning of "PIECEWISE" in Ls-Dyna material "MAT_PIECEWISE_LINEAR_PLASTICITY(MAT_24)".
Thanks in Advance.
i working on impact, and I should model the penetration in armour, last time i modeled it by LS -DYNA and now I working with abaqus, but it does not have material model for ceramic. accordingly, i should write the VUMAT, but i do not know how I start.
I need some reference for starting to write subroutine. please help me

Hi friends
how can i define solids porosity in abaqus
for example i want simulate a plate with 90% porousity that in under tension
thanks
Hi,
I am using a bridge model with Tet element as mesh in the structure. I have given many static loads in deck surface . After submitting 'Job' gets stresses of different element label of the deck as report. I want to now calculate the volume of single element (tet element) so that I become successful in calculting the damaged volume due to the load. Is there any option to get the volume of the meshed elements.
Thanks in anticipation.
Nidz....
