Hi, how can I find the number of elements or nodes in my model?
Many Thanks...

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.

Subject: [EXTERNAL] Re: [Abaqus] referencing amplitude in VDLOAD subroutine

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..

Thank you

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

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 You
Abhishek
