Interpreting flat code and counting equations in Dymola

Asked 2018-Jan-29 at 11:30

I am having trouble locating the source of an additional unknown in a modelling project I am working on. I am getting an error saying I have 34 unknowns and 33 equations. I decided to look at the flattened code in Dymola, and while I can count the correct number of variables, I cannot find a way to reach the 33 equations. Below is the flattened code:

...

Unfortunately the flattened code does not contain all the necessary information.

However, it is a good start and contains 27 equations:

2 binding equations
2 scalar equations in the extends Modelica.Media.Interfaces.PartialMedium.BaseProperties_D1
7 equations in SolarTherm.Media.MoltenSalt.MoltenSalt_base.BaseProperties outside the base-class
16 equations in PentakomoPlant.Storage.HeatStorage.

But in addition there can at least be:

Bindings of records (none in this case)
Flow-variables in top-level public connectors; in this case I would assume it 2+2+1+1 (fluid_a, fluid_b, heat_PB, heat_DS).

The top-level public input Q_heater can be handled in two ways, and as I recall Dymola has used both variants: either it does neither contribute to unknowns nor to equations (seen as a known variable), or it adds one to both.

QUESTION

Balancing local models Modelica

Asked 2018-Jan-25 at 13:19

I have a local model, which when I check in Dymola claims to have 35 variables and 34 unknowns, while when I check exactly the same model in OMEdit it is balanced at 34/34. In determining what counts as a variable, do all inputs and outputs get included?

Below is my model:

...

ANSWER

Answered 2018-Jan-25 at 13:19

The model is not complete with all libraries to enable testing (assumedly there are similar issues with other media), so this will be an incomplete answer.

In addition it seems likely that some equations and variables could be removed to simplify the model.

But there are some concerns with the model:

T_amb_internal is unused and undeclared; that looks odd.
You normally need equations for two intensive properties for simple medium: e.g. p, h or p, T. Here medium.h is determined due to the differential equations, but not medium.p. (The mass also has a differential equation and can vary.)

Note that testing of a local model can be tricky - and you should preferably include it in a test-circuit as well.

QUESTION

How to Set an Inteval on Angular 2 Http Observable Request

Asked 2017-Jan-27 at 02:51

I made an Angular 2 service that successfully gets data from my server. It has one function named getSinglePowerBlock. The goal of this function is to setup an observable to make the get request to the given URL, and return one of the powerblock elements from the JSON property assets.powerblock[]. I know this works successfully, because I can get it to work in one of my components. I have included that component, for reference.

My Goal: I want my code to make the get call continuously, once per second, using the interval function from the rxjs library. Then, I want my local data to update with the data from each poll response. Basically, a polling solution.

I imagine it's not hard to do, but I'm new to Observables and Rxjs and I just can't seem to get the syntax correct. Feel free to offer a better way to do the getPowerBlock function or the way I'm calling it. I'm sure you're much smarter than me at this.

I only want the polling to be on when this component is the current page being viewed by the user.

The Service:

I don't think so its wise to call an interval on a returned promise/observable but if you are just returning the data (not observable/promise), you can do this inside the timer in angular2. It will continuously call the function after 1 second

Vulnerabilities

No vulnerabilities reported

Install PowerBlock

There comes an installation script with this reposity that does all the steps described below: install.sh This script compiles the driver, installs the binary and configuration files, and installs the PowerBlock service. To run the quick installation, you just need to call this one line from the Raspbian console. To uninstall the service you can simply call sudo ./uninstall.sh from within the PowerBlock directory.
This section is about installing the PowerBlock service on LibreELEC. In the following, it is assumed that we install the driver on a fresh, unmodified LibreELEC installation. First, use SSH to log into the running LibreELEC instance. This can be done, e.g., with the command ssh root@IP_OF_LIBREELEC. The default password is libreelec.
