Need guidance on Capella usage

Capella

Hello All,

Hope you are doing well !

I am new to Capella (using version 7.0.0), exploring ARCADIA to fit into my organisation’s MBSE framework.
I need guidance on resolving few tool usage queries which I am unable to resolve on my own. I went through few videos and user guides, however I could not find answer to the below ones.
Request to support me in resolving these queries.

  1. If we edit a Function name or Functional exchange name in a phase, how do we reflect this update in the next or previous phases ?
    Ex: In System analysis phase, I have defined a system function (SF) ‘Compute demand clutch position’ and one of the functional exchange input name for this SF is ‘clutch position’. The functional transition for this SF has already made to Logical Architecture phase. The function ‘Compute demand clutch position’ is seen as Logical Function (LF) in Logical Architecture phase. After further analysis, I decide to change the name of function to ‘Compute and Monitor clutch position’ and change functional exchange name to ‘current clutch position’ in System analysis phase.
    Now, how do I transition these changes to Logical architecture phase ? When I used Functional transition on the modified SF, I see no updates available in the Functional transition window (refer attachment). Is it possible to please advise on how to transition the modified names to other phases ? All I am doing at present is searching the changes in all phases and editing manually.

  2. How to revert back the hidden elements of Architecture Diagram (PAB) in Diagram editor ? For example, I select a node PC in Diagram editor and hide it using Ctrl+H or ‘Hide Element’ in the selection. Later,I realise that I need that node PC to be visible. if I wish to bring it back I do not see any option in the selection. There is a button called ‘Show element’, however if I click that button, I see no changes.

  1. In Architecture Diagram (PAB) how to change the line width of Physical links ? I see options to change, however they are not active.

  1. Is there an option to see the traceability of an element end to end. For ex. a Physical Function in Physical Architecture mapped till a Mission in System Analysis phase in one view ? As of now I believe the traceability is restricted to phase-wise.

Cheers !

Hi Hemanth,

Welcome to Arcadia/Capella!

Please find some answers here:
1 - The tool is not detecting any change because having a different name between functions at different level of engineering is expected. The transition mechanism in Capella is here to help you to initiailize things. But you are actually expected to change this names in general (and not only changing names of course…). If your process is to transition functions and components from one level to another, keeping their names concistents and doing just some refinements (sub componenents, sub-functions), then there is no added value in going through these engineering perspectives, as you end up having all the same elements again and again at each layer with only more refinements. This is not the meaning of the different engineering perspectives in Capella. This is a much longer discussion… some beginning on insights on this on this thread: Why can Operational Activities be transitioned to System Capabilities/Missions?

2- See one way to do it here:
hiding

3 - I beleive it is discouraged to change line width of phyisical links as you would also generally create Phyisical Path (“similar” to functional chains) that will alter the width of the line. Nevertheless, you can do it by going to the Property tab and Style sub-tab and change the Size attribute value there (selecting first your physical llink).

4 - I beleive some organizations have this capability in their environment, not sure. There was an open-source attempt to do that as a Capella add-on here: GitHub - labs4capella/cross-level-analysis - I beleive this is not compatible with Capella 7.0 as the only build availalbe are for Capella 1.4.2 / 5.1 / 5.2

I hope this helps.

All the best,
Stephane

Hello Stephane,

Thank you very much for the detailed answers. This helps a lot !

Will keep posting if I come across any further queries.

Cheers !
