use of functions in asterstudy

Hello everybody,

this is a novice question. I hope nevertheless that someone will be so kind to help me.
I struggeled several hours trying to find out how functions, equations and lists work in AsterStudy.
I have a very specific question.
I modelled a concrete dam on soil.
I made a function loadW for the hydrostatic pressure on the dam.
When I try to assign the mechanical load in PRES I have no idea how to assign my function to PRES.
I have to options: a numerical value or add variable. How to link my function?

Kind regard,

Roger

Hello,

depending on the analysis and assuming you are doing a STAT_NON_LINE analysis, in the EXCIT section where you
assign the loads there is also the option to assign the function that the loads will follow.

Re: use of functions in asterstudy

I succeeded by switching to text input:

55 loadw = AFFE_CHAR_MECA_F(MODELE=damsoil, PRES_REP=
56                                                  _F(GROUP_MA='loadW',PRES=loadF,),);

loadF is the loadfunction I could enter from within the GUI.
However I did not find how to enter the loadw from within the graphical interface.
