Modelica arrays with unspecified dimension

问题

Given a model with an array x of connectors where its size is unspecified, e.g.

connector con
...
end con;

model test
con x[:];
end test;

How can x be instantiated with a specific size, e.g. something like this?

test t(x = ?);
...
equation
connect(t.x[1], a);
connect(t.x[2], b);
...

回答1:

Why do you need unspecified dimension? You can do something like this:

connector con
...
end con;

model test
 constant Integer dim = 1;
 con x[dim];
end test;

// usage
test(dim = 10);
...
equation
  connect(t.x[1], a);
  connect(t.x[2], b);
...
