Dymola-specific functions in MSL (Tables and Utilities)

[modelica-trac-importer]

Reported by TorstenBlochwitz on 28 Nov 2008 08:58 UTC
The MSL (2.2.1 and 3.0 at least) makes use of Dymola-specific functions dymTableTimeIni2, dymTableTimeIpo2, dymTableTimeTmin, dymTableTimeTmax, dymTableIpo1, and dymTableInit and some more in the utilities package.

Due to this situation, the MSL is not self-contained. The tool vendors have to implement these functions themselves. This could lead to different results depending on the implementation.

Anton Haumer provided an offer for the implementation of functions for tables as discussed at the 57th meeting in Lund. At the 59th meeting we did not decide about this offer.

The current implementation is also lacking derivative annotations for the (external) table functions, which causes all models that contain tables to sabotage the generation of symbolic Jacobians. That problem should be fixed at the same time.

From [milestone:Design63]

Martin Otter presented a proposal how to fix the table issue (introduce basic functionality in ModelicaServices for parsing text and binary files and to handle dynamic arrays and maps via the external C-interface; based on that provide a pure Modelica implementation; partial prototypes are available). A Modelica task-force "tables" with email list ModelicaTask-Tables@ has been set up (Toni, Dietmar, Hans, Hilding, Johan A., Gerd, Martin, Peter A.). This task group will define the interfaces of the base functions and the definition of the payed work until the next design meeting. After a final discussion at the next design meeting, the "call for quotation" to implement the missing open source table support will be sent out.

TaskForce will work on this.

Hopefully this can be done in time for [milestone:Design67]

This task group will define the interfaces of the base functions and the definition of the payed work until the next design meeting.

So far not much progress on this topic. Rescheduling to [milestone:Design69]

The proposal from Design meeting 63 should finally be executed. Has anything happened w.r.t. the definition of the interfaces and the definition of a statement of work? I think that the TaskForce:Tables really is in the duty here to deliver the proposal from Design63. There could eb some scope for this work within the OPENPROD project, maybe?

Left-over tickets from an older Design meeting. Rescheduling to next design meeting to be reviewed.

The table code will be fixed soon.
Torsten, could you specifiy which external C-functions of Utilities are not freely available?

MA has given a contract to ITI to provide an open source implementation of the tables. MSL 3.2.1 shall be released with this implementation.

Fixed in 8b1c969:

The finalized open source implementation of the tables and the adapted table blocks from ITI have been included in MSL trunk.
