Moving Pressure in ABAQUS

[ArashRa]

Dear Friends,

Mary Mary Christmas & Happy New Year.

I want to model a Moving pressure which act on the set of C3D8 elements. could anybody give me any advise in this regard?

for your information, consider a model which has 10 elements in longitude direction and the load acts on the surface of the first element at the time=0 then after time=0+DeltaT it become zero on the first element and act on 2nd element and ... till it reach to the 10th element at time=0+10*DeltaT.

Thank you very much
Arash

You can try to use the DLOAD subroutine which "can be used to define the variation of the distributed load magnitude as a function of position, time, element number, load integration point number, etc.;"

Hi,

I assume you have access to Abaqus documentation. If not do a google search, you might be able to find some web-sites with unresctricted access.

There is a manual in Abaqus documentation called "Abaqus User Subroutines Reference Manual" describing the user subroutines. Look for DLOAD and UTRACLOAD

Also, in Abaqus Analysis User's Manual there is a section called Loads -> Distributed loads.

There is way more info in the documentation than I could post here.

Best.
