I am trying to use expressions to set up initial conditions, but I have syntax issues to get components from vectors.

Example:

var1 #eval { vector(1, sqrt(2), 3) };
var2 #eval { vector(var1.x(), 4, 5) };

the syntax above is not correct, and I tried a few variations of it without luck.

the resulting error is "Object var1.x does not exist or wrong type in expression at position...".

What is the correct syntax to use a component out of a defined vector?

Thank you in advance

ok, I found the answer in the user guide

basically if I define a vector

var1    #eval{vector(1, 5, 3)};

the vector components are accessed using the expansion

$[(vector) var1]

for example if I want to define another vector using the "y" component from "var1", I should do

var2    #eval{vector(4, $[(vector) var1].y(), 6)};

hope it helps!

Cheers
