randomVariablePositioner problem

[karimtarbali]

Hi

i use randomVariablePositioner in this format : randomVariablePositioner $tag –rvTag $rvTag –parameter $pTag
but i get this error : ERROR: Illegal random variable specification in randomvariable positioner command.
while executing
"randomVariablePositioner 1 -rvTag 1 -parameter 1"

Could you please tell me what could be wrong?
thanks

You need to create the random variable before you can position it. This would entail the "randomVariable ..." syntax that specifies the type of the variable and it's parameters. Also, you are trying to associate the random variable with a parameter, so you need to have the parameter pre-defined.

i was thinking that the tag of the section is the one we define by fiber command but the tag of section is the tag of sections for lobatto intergration.
