Hi all,
I am using VOF model and I want to get the surface tension value through the TUI by rpgetvar so I can use it in a udf. I wander if it is possibale.

using scheme file you may create any king of variable

(define (make-new-rpvar name default type)
	(if (not (rp-var-object name))
		(rp-var-define name default type #f)
	)
)
(make-new-rpvar 'my_surface_tension 30.0 'real)

in UDF you can access this variable:

surf_tension = RP_Get_Real("my_surface_tension"); //get parameter
RP_Set_Real("my_surface_tension",60.0); //set parameter

best regards

Thank you for your replay

I can use the GUI to set the surface tension coefficient by going to the phase interaction>surface tension>surface tension coefficient.
how can I get this value through the TUI?

i used the code (cx-send '(for-each (lambda (v) (pp v)) rp-variables)) to get the variable scheme list and the surface tension coefficient is part of the domains variable but I do not know how to use the rpgetvar to get the value of the surface tension coefficient.

(rpgetvar 'variable_name)

try this

(rpgetvar 'mp/cvt/surface-tension)

Thanks a lot.
