VDISP in ABAQUS

[Engineer Dr. Pan]

Hi everybaody,
I am studying VDISP in ABAQUS.
I want to prescribe the displacement,
I try to read help document of abaqus,
but I do not konw how to define dispalcement in VDISP,
please support data or examples for me,
thank you.

In the Verification chapter of the documentation is an example.

Abaqus documentation is pretty much always the best source of information in such cases. First take a look at the VDISP chapter of User Subroutines Guide - there you will find a description of this subroutine, its interface and example. Then go to Verification Guide where you can find another example of this subroutine.

Hi, FEA way and Mustaine3,
I am studying abaqus documentation, thank you!
but how can I define the coordinate of a node (X,Y,Z) in VDISP,
for example, I can define the coordinate of node in DISP
X = COORDS(1)
Y = COORDS(2)
Z = COORDS(3)
Or, how can I call the COORDS in VDISP?
Please, thank you

Did you had a look into the documentation? It says:

coordNp(nCoord, nblock)
Nodal point coordinates.

Some helpful tips -

Have you tried to execute a VIDSP job? If yes, make use of write statements to try to make sense of what the variables mean, what the code is doing, etc. In fact, if you have set-up your IDE (e.g., Visual Studio) well, you may even be able to "watch" variables as the code is being executed one line at a time. Alternatively, you could write a wrapper script around any FORTRAN code from the verification manual, provide it all the information it wants for successful execution, and you can run the code without even executing Abaqus.
