variable step time and pressure

[mariem]

Hello, i'm trying to model the impact of a water droplet on a solid with abaqus. my loading time as well as my pressure are variables they depends on R (the position of the droplets in the R axis)

How i can enter a variable loading time?

Thank you.

Time variation can be done with an Amplitude or a user subroutine.
Spatial variation can be defined with an Analytical Field or a user subroutine.

But the options without subroutine require, that you know in advance where and when what loading has to be applied.
