referencing amplitude in VDLOAD subroutine

abhishek-2
Hello respected fellows
I am facing a  problem in defining amplitude in VDLOAD subroutine. I am not able to understand as written in manual ' referencing amplitude', how to reference amplitude in VDLOAD subroutine?
Thank YouAbhishek

Mohammad Malekan
Hello Abhishek,
Please explain what kind of problems do you have with amplitude definition within VDLOAD?
Regards,Malekan

Dear Abhishek;
Did you link successfully your subroutine to Abaqus?

Re: referencing amplitude in VDLOAD subroutine

abhishek-2
 Sir  Thank you for replyingI wrote a subroutine VDLOAD for dynamic explicit analysis in ABAQUS. the load is spatially distributed as well as varying with time.the spatial distribution works fine. For variation with time I made an amplitude in CAE module but it is not behaving as desired.As in VDLOAD subroutine there is an amplitude variable which is un-modifiable.i want to ask what is the use/function of that variable?should i need to write codes for the variation with respect to time of 'press' or it will be done automatically ?
and in manual if we see in subroutine VDLOAD, in explanation it is written that the 'press' value should be multiplied by 'amplitude', Why?I am attaching a google drive link of my simulation file please have a look.

Re: referencing amplitude in VDLOAD subroutine

Mohammad Malekan
Dear Abhishek,
Whay don't you define your time-varying load within VDLOAD subroutine? Instead of writting an time-varying amplitude and multiply that with your load, use VDLOAD and write everything about your load in that.
The amplitude parameter inside of VDLOAD refers to "magnitude" parameter that you have to define with user-defined load.
Hope it helps you,

RE: Re: [Abaqus] referencing amplitude in VDLOAD subroutine

In reply to this post by abhishek-2
The amplitude variation is defined using the *Amplitude keyword.  The current value of the amplitude is passed into the subroutine and can be used in the calculation of the load.

Sir  Thank you for replying
I wrote a subroutine VDLOAD for dynamic explicit analysis in ABAQUS. the load is spatially distributed as well as varying with time.
the spatial distribution works fine. For variation with time I made an amplitude in CAE module but it is not behaving as desired.
As in VDLOAD subroutine there is an amplitude variable which is un-modifiable.
i want to ask what is the use/function of that variable?
should i need to write codes for the variation with respect to time of 'press' or it will be done automatically ?

and in manual if we see in subroutine VDLOAD, in explanation it is written that the 'press' value should be multiplied by 'amplitude', Why?
I am attaching a google drive link of my simulation file please have a look.

RE: Re: [Abaqus] referencing amplitude in VDLOAD subroutine

David Lindeman
One way is to use Python.  In the Python command window, use something like:

model = mdb.models[‘myModelName’]
numberOfNodes = 0
numberOfElements = 0
for key in model.parts.keys():
  part = model.parts[key]
  numberOfNodes += len(part.nodes)
  numberOfElements += len(part.elements)
print ‘Number of nodes =  ‘, numberOfNodes
print ‘Number of elements = ‘, numberOfElements

Note that you’ll need to adjust the logic if you have multiple instances of a dependent part, or if you’re using independent part instances (the mesh will be associated with the part instance, not the part, in that case).
