General Board / Re: SysML: How to create model libraries

« on: February 18, 2010, 02:42:32 am »

thanks for your answer.

but i still don't have any idea on how to instantiate model elements from the model library. the only way i found was to inherit from model elements but that is something totally different to me.

General Board / SysML: How to create model libraries

Are there any examples for creating model libraries in EA? I am missing a package stereotype <<modellibrary>>. How can i use parts of those libraries?

Thanks

General Board / Re: SysML: How to setup EA?

« on: January 02, 2010, 09:41:27 pm »

I understand SysML as a fully defined language, which can be used to model any technical system completely. Therefore it is IMHO not important, that SysML intersects UML. If one wants to use SysML and UML together, EA should support this optionally.

The reasons why I prefer a clean tool for SysML are:
1. the superset of all systems, which can be modelled with SysML, also contains those, which do not consist of any piece of software.

2. system engineering in large companies is done mostly by classical engineers not by software developers. Those people usually have a rather limited ability for abstraction (hurdle 1) and no knowledge about software development processes or UML (hurdle 2). The approach of MBSE is a huge break with common engineering methods. To bring those people close to MBSE among other things a tool is needed with a minimum of complexity, which can be learned/used easily and hence reduces the risks of maloperation and integration of errors into system models. Any "unneccessary" stuff flattens the learning curve and therefore bears the risk of refusing the tool in the first place and consequently the method by the staff.

I want to model systems with SysML1.1, so i tried to setup EA for using SysML 1.1 only. It seems not to be possible, since the whole IDE is "poluted" with things which aren't part of SysML but are part of UML (e.g. certain stereotypes, attribtues).

Is there any chance to configure the IDE so that it is pure SysML?

Bugs and Issues / Loosing tags when instantiating associations

« on: April 13, 2010, 03:24:52 pm »

using EA 7.5 (SysML) i created a new instance of a block, which contains an internal port connected by an association to an external port. the "original" association contains tagged values which get lost after instantiation.

is this a bug and is it fixed in EA 8.0?

Bugs and Issues / Re: Problem with locked ports

and has it been also fixed, that if you open the properties off a instantiated flow port, the arrow(s) of the port vanishes so it looks like a standard port?

Bugs and Issues / Problem with locked ports

« on: April 10, 2010, 10:11:54 pm »

Hi,

using EA 7.5 (SysML) i created a new instance of a block, which contains a port. the port of the new instance is locked automatically (shown on the context menu - right mouse button click on the port) and i found no way to unlock it.

Is there any way to unlock the port?

thanks
Matthias
