Support the Buildings library

[Francesco Casella]

OMC should fully support the Buildings library. Some reference reports to check the current status:

• ​Buildings_latest coverage with OpenModelica/NF
• ​Buildings_latest coverage with JModelica

• Coverage trend with OpenModelica/NF:

[Francesco Casella]

@perost, can you please comment on the status of your efforts to increase the test coverage of this library?

Thanks!

Here is a list of know pending issues with the Buildings library 7.0.0, also see the ​Jenkins report.

Frontend

• #5988 NFTyping.typeComponents fails with no error message
• #5991 NFTyping.typeComponents fails with "Could not evaluate structural parameter (or constant)"
• #6188 NF Type mismatch in Buildings model involving redeclared class
• #6193 NFFlatten.flatten unspecified error
• #6203 Some parameters seems to be never assigned in Buildings models
• #6206 The NF fails to evaluate expression in Buildings library
• #6208 The NF does not recognize parameter variability of records of parameters
• #6221 The NF ignores a redeclare statement in a record containing a replaceable package and a function call from it

Backend

• #6095 Large numbers of variables are lost in the backend when matching
• #6190 Issue with Pantelides' algorithm and homotopy
• #6196 Bogus linear tearing
• #6198 The backend tries to differentiate a discontinuous expression
• #6199 Mixed under/overdetermined initialization problem
• #6200 Evaluating parameter-dependent redundant and possibly inconsistent equations
• #6207 Mixed-determined initialization problem

Code Generation

• #6197 Issue with code generation involving records
• #6205 Issue with code generation involving records
• #6209 Issue with code generation involving arrays and records

C Runtime

• #5281 Add support of spatialDistribution() operator
• #6194 Chattering involving arrays.
• #6195 Incorrect triggering of asserts on variables computed by conditional equations
• #6204 Issue with temporary file
• #6210 Linker error

NF API

• #6189 getElementAnnotation is very slow on some models

OMEdit

• #5631 Fix DynamicSelect for new API
• #5796 Very long fully qualified model names cause problems in OMEdit under Windows

Library

• #6192 Initialization fails because of division by zero in homotopy

[Per Östlund]

#5281 and #6095 are not frontend issues.

[Francesco Casella]

Replying to perost:

#5281 and #6095 are not frontend issues.

Indeed, sorry for the mistake.

[Andreas Heuermann]

Is this correct: #6110 Linker error

#6110 is about OMEdit.

[Francesco Casella]

Replying to AnHeuermann:

Is this correct: #6110 Linker error

#6110 is about OMEdit.

Sure. That should have been #6210, I made a typo.

[Francesco Casella]

This ticket is now obsolete, see #6281
