Out-of-memory issue during instantiation in IDEAS library

12

Some models of the IDEAS library, e.g. [IDEAS.Examples.PPD12.Heating](https://libraries.openmodelica.org/branches/master/IDEAS/files/IDEAS_IDEAS.Examples.PPD12.Heating.err) fail with ``` Warning: Out of memory! Faking a stack overflow. Error: Stack overflow occurred while evaluating translateModel(IDEAS.Examples.PPD12.Heating, tolerance = 1e-06, outputFormat...

Currently, https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/ has a symbolic link to https://openmodelica.org/doc/OpenModelicaUsersGuide/1.20/. We need to make sure that this link is updated when a new release comes.

@perost, among the various issues in the latest [regression report](https://libraries.openmodelica.org/branches/history/master/2022-04-24%2011:23:12..2022-05-14%2000:36:35.html), there are Buildings models such as [Buildings.Fluid.HeatPumps.BaseClasses.Validation.EquationFitReversible](https://libraries.openmodelica.org/branches/master/Buildings_latest/files/Buildings_latest_Buildings.Fluid.HeatPumps.BaseClasses.Validation.EquationFitReversible.err) that fail during flattening with ``` [Buildings 9.0.0-master/Fluid/HeatPumps/Data/EquationFitReversible/Generic.mo:21:3-49:25:writable] Error: Protected sections are not...

Since a while ago, the backend has been capable to generate symbolic Jacobians for the RHS of the causalized ODE equations. The option is activated with the flag [--generateSymbolicJacobian](https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/omchelptext.html#omcflag-generatesymbolicjacobian), which...

Add a (structural) variable filter to the backend for efficient simulation

7

The current runtime allows to select which variables to write to the simulation result file, by selecting [Simulation Setup | Output | Variable filter in OMEdit](https://www.openmodelica.org/doc/OpenModelicaUsersGuide/latest/omedit.html#output), or by providing a...

The ClassLoader currently uses external C code to accomplish the task (see [this comment](https://github.com/OpenModelica/OpenModelica/issues/8881#issuecomment-1114834238)), and is not well integrated with the package manager. The loadModel() API uses the package manager...

On several occasions, OMC returns outputs with badly rounded decimals, whenever the float representation of the decimal number is not exact, for example - when returning flat Modelica output (see...

Reduce timeout for interaction with the package manager server

The current timeout when trying to communicate with the package manager server is set to the default of libcurl, which is 300 s (!!). Waiting for 5 minutes for a...

Missing library prevents using --parmodauto under Windows
