Check conversion to IBPSA

[bramvdh91]

I have tried to run the python conversion script as I noticed a lot of our components were not copied to the IBPSA folder. I'm not sure if everything is working now, since I had to change the pressure drop component to the new "HydraulicDiameter" FixedResistance.

Could you please check examples/tests that you consider important and see if everything is working as expected?

I do not see any major problem. But it would be good to

• propagate the HydraulicDiameter parameters (ReC, roughness, fac, allowFlowReversal, ...)
• dp_nominal is not used anymore. We can remove it or suggest to change HydraulicDiameter. In this regard, HydraulicDiameter uses _default value for rho, mu, ... it would be good to be able to edit this values. Related to Re-introduce pressure drop calculation based on medium properties #48.

Good point.
In the meantime I am not able to compile our validation examples (ULg and AIT), and I'm a bit puzzled about the reason... Dymola gives the following on translation:

In nominal attribute for pipe.pipeAdiabaticPlugFlow.res.dp.
Ignoring nominal attribute.
In class Modelica.SIunits.
Near file: C:/Program Files (x86)/Dymola 2017 FD01/Modelica/Library/Modelica 3.2.2/SIunits.mo, line 2
Used in base-class pipe.pipeAdiabaticPlugFlow.res.PartialTwoPortInterface.
Near file: C:/Users/u0094934/Documents/Dymola/modelica-ibpsa/IBPSA/Fluid/BaseClasses/PartialResistance.mo, line 3
The DAE has 271 scalar unknowns and 271 scalar equations.

The initial conditions are not fully specified.

After that, there's two errors, both the same:

The system is out of memory or resources
Compilation of IBPSA.Experimental.Pipe.Validation.ValidationPipeULg failed.
Note: There were translation errors that might explain the problem.
Compiling
Errors were found
Warnings were issued

This while my computer is clearly not out of memory, and no clear message about which errors were found is given.

I Could translate and simulate the \Validation models (I am using Dymola 2017 and Visual Studio 2010...).

I have but a different number of scalar unknowns... I guess you posted Dymola messages related to Validation\ValidationPipeUlg ?

Translation of IBPSA.Experimental.Pipe.Validation.ValidationPipeULg:
Non-literal value.

The DAE has 280 scalar unknowns and 280 scalar equations.
The variable pipe.tau_used.inp_a is not a continuous time state,
which means that existing reinit has no effect.

Maybe is something wrong with your repository.

Apparently Dymola all of a sudden forgot where my C++ compiler was located... Working again now :)
