SysML Itemflows and directionality in general

[RayB]

Hi all,

I haven't been able to find how to add directionality to my connectors.

I'm using v1.4 so no atomic flow ports.

So I have an interface block to type the port for example DVI (Video) I could have invideo outvideo as basic flow properties.

How do I represent the direction flow on my IBD connectors? Does anybody have a link to an item flow user guide or is it still possible to annotate the directions on the port outside of the naming?

Is it as simple as going to andvanced and indicating direction on the connector via source to destination or vice versa?

......

I may have answered my own question. I right clicked on the connector, clicked item flow realised, selected the same block that typed the ports and then indicated the direction. Please let me know if this correct.

Many thanks in advance to the gurus out there.

Hi,
this is how it works:

You need to create a block or an interface block
add a flow property to that block and set the direction to whatever direction you want
classifiy your port with that block

Hi Peter,

Thank you for your reply, I have had some success with this and have created an inout ports by typing by a block with an inout flow property and I have the nice bi-directional indication in the port itself.

However on another port, the one where I want Item flow, the ports are not bi-directional i'm not having the same success.
The block typing the port in this case is not bi-directional but in:video, out:video so it is point to point information flow which I have managed to create by;

Right clicking the connector
Advanced -> information flow realised -> set the type -> set source and target

So I have a point to point unidirectional flow indicated by the typing block and the item flow, however the ports are still showing arrows in both directions like the old non-atomic ports rather than a single arrow like the atomic flow ports.

Any ideas where I might be going wrong?

You have to select your "flow property" and under "Element Properties" under the Tab "SysML 1.? you have the change the direction to in or to out.
