Roadmap and Current state OpenModelica

[Peter Fritzson]

Dear Thore,
See my answers below.

- Since 2-3 weeks, we have increased the manpower to
4 full-time developers on the OpenModelica compiler
in order proceed faster with MultiBody and Fluid/Media library support.

Subject: Request for get to know the state of OpenModelica...

Dear Modelica Community.

I would like to get to know the state of OM regarding the following issues:

1. Is the building model library of LBNL of Matthias Wetter able to be used
(newest version needs stream connectors)?

- It don't think so, but we have briefly discussed that library. However,
the standard
Modelica libraries have higher priority.

- In the past 3 weeks we have made quite a bit of progress and
fixed many issues with Fluid/Media. Stream connectors are on the list to be
fixed.


2. ExternalMedia is available as a direct link between Modelica and
FluidProp. Is this running?
- We have not tested yet.

3. Is the Spark Solver added to the OpenModelica Solver family?

- No, not yet. Are you interested, would like to contribute?. 
DASSL is the standard. We have Euler and Runge Kutta
in non-released prototypes.  We have had no requests for the Spark Solver
yet (as far as I know).

4. Is the ModelicaFluid Library fully supported now?
- Not yet, but a lot of progress in the recent 2-3 weeks.

5. Would the FlowDissipation developed at TUHH and XRG run within
OpenModelica?
- They will need to be tested by TUHH and XRG. See also above.

6. Do you know in any form the state of interoperability between
SciLab/SciCos/Xcos and OpenModelica?
- This interoperability is a task in the OPENPROD project, and one person in
our group has been allocated to that task.
- If you have testcases/use cases, this would be useful.

7. What is the roadmap of OpenModelica in the next months/year to get a hint
on compatibility in the above mentioned fields?

- See roadmap on www.openmodelica.org

-My estimations today, Dec 21, 2009:

MultiBody and Fluid/Media flattening in January 2010.
Fluid/Media simulation in February 2010.
Simple MultiBody Examples simulation February 2010
More complete MultiBody Simulation Fall 2010 (Tearing support is needed)

8. What activities are running in getting a benchmark between Dymola and
OpenModelica? Are recommendations and wishes as presented by the Siemens
Team (K. Link et al.) on the Modelica 2009 be realised already?

- Could you give a link to that presentation?
The Siemens Team is in the OPENPROD project, and to support their needs
is in the project plan.


Thanks for your help!

Best regards,
Thore Oltersdorf
