i have been running a transient analysis, with acceleration vs time has a my input for Modal transient.
want to now what will be my excitation input in SPCD card
Hi,
I am sorry but could you please explain what do you mean by excitation input in SPCD?
Do you mean in TLOADi card?
yes,
TLOAD1 card only
TLOAD1 3 10 ACCE 11
SPCD 10,1,9810
TABLED1 11, ( inputs are in time(s) vs Acceleration (g)
Hi @Murasoli
The TLOAD1 looks fine. You are passing the solver that the load type is acceleration.
if i use this type of input, is that i will get out put acceleration in (g or mm/s^2)
i'm getting stress are very high
if my input in this type
HI,
It should the unit which you used.
What about displacements?
Can you add ENFMOTN>>REL card and check the results?
displacement also high only
how this card works (ENFMTON>>REL)
WIthout ENFMOTN>> REL the displacement and accelerations, etc... are absolute values and stress is calculated based on total displacement
With ENFMOTN>> REL the values will be relative to applied enforced motion
Yes its good, Getting relative Displacement and acceleration
And still stresses were high, As same as without ENFMOTN card
Are you looking at SDISPLACEMENT values?
Is it possible to share the .out file and if possible share the model as well.
Please use the file transfer link in my signature to share the model file
please check the files which i have shared.
Is possible give a model which can be correlated with FRF and Transient
I am checking with experts and I will get back to you soon.
hi
you got any answers for that
Not yet, I have shared details already awaiting feedback.
I will leave a reminder.
