floris is a Python library typically used in Testing, Functional Testing, Framework applications. floris has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub.

FLORIS is a controls-focused wind farm simulation software incorporating steady-state engineering wake models into a performance-focused Python framework. It has been in active development at NREL since 2013 and the latest release is FLORIS v2.4 in July 2021. The v3 branch of the repository contains an architectural redesign of the software to enable improved performance in AEP calculation and controls optimization. We are actively seeking beta testers for the new framework. If you are interested in using FLORIS to conduct studies of a wind farm or extending FLORIS to include your own wake model, please get in touch!

            Why django is not detecting my table column?
            Asked 2021-Jul-06 at 11:29

            I have a problem. I've created model called "Flower", everything works fine, i can create new "Flowers", i can get data from them etc. The problem is when I want to use column "owner_id" in SQL query I got an error that this column don't exist, despite I can use it to get data from objects (for example flower1.owner_id). I've deleted my sqlite database several times, made new migrations and used migrate but that still not worked.I also changed name of the column and re-created it, but that still doesn't helped.

            ANSWER

            Answered 2021-Jul-06 at 11:05

            Since owner_id is declared as a ForeignKey, it will be available in the actual SQL database as owner_id_id. The additional prefix _id is automatically appended by Django for that relational field. When using Django ORM, you would just access it via owner_id then Django will automatically handle things for you in the background but if you are using raw SQL command, then you have to use the actual table column name which is owner_id_id. If you don't want such behavior, set the db_column of the model field with the exact name you want e.g. owner_id = models.ForeignKey(User, on_delete=models.CASCADE, default=1, db_column="owner_id").

            As stated in Django documentation:

            Behind the scenes, Django appends "_id" to the field name to create its database column name. In the above example, the database table for the Car model will have a manufacturer_id column.

            How to plot a graph with a side bar as a legend using Floris lib from NREL?
            Asked 2021-Jun-21 at 12:43

            I am using the Floris library from NREL for Python in order to simulate wind wakes after a wind turbine (see https://github.com/NREL/floris). In the example 1 of section "Getting Started" (see https://github.com/NREL/floris/blob/main/examples/_getting_started/example_00_open_and_vis_floris.py) I am plotting the result for a single turbine. This is the output:

            Wake for 1 turbine

            However, I would like to add the side legend bar on the right (see black circle), like in the next figure:

            Wake turbine with side bar

            I cannot show the full code because the floris library from NREL has a lot of user-defined functions (this is why I provide the links). The code for the example I mentioned is:

            Is .isin() faster than .query()
            Asked 2021-Jun-04 at 11:32
            Question:

            Hi,

            When searching for methods to make a selection of a dataframe (being relatively unexperienced with Pandas), I had the following question:

            What is faster for large datasets - .isin() or .query()?

            Query is somewhat more intuitive to read, so my preferred approach due to my line of work. However, testing it on a very small example dataset, query seems to be much slower.

            Is there anyone who has tested this properly before? If so, what were the outcomes? I searched the web, but could not find another post on this.

            See the sample code below, which works for Python 3.8.5.

            Thanks a lot in advance for your help!

            QR-Factorization in least square sense to solve A * w = b
            Asked 2021-Jan-10 at 10:42

            I'm trying to implement the QR24-Algorithm to calibrate flange/tool and robot/world from this paper by Floris Ernst (2012).

            I need to solve an equation M_i*X - Y*N_i = 0 where M_i and N_i are known and i from 1 to the number of measurements and X and Y are unknown Matrices.

            In the paper they combined this equation into a system of linear equations A*w = b, where A consists of 12*number of measurements rows and 24 columns, so I have a system of linear equations with 24 parameters, where I need at least 2 measurements to solve this system.

            To solve this equation, I need to use the QR-Factorization in least square sense because with more measurements, this system has more equations than parameters.

            I'm using the OLSMultipleLinearRegression from the Apache Commons Math library to solve the equation system:

            I was able to find a solution to my problem and I want to share it with you. The problem was not a programming error, but the paper provided an incorrect matrix (the Ai matrix) which is needed to solve the linear system of equations. I tried to extract a system of linear equations from M*X - Y*N = 0 by myself using the characteristics of homogeneous transformation matrices and rotation matrices. I came up with following solution:

            The vector bi provided in the paper is fine.

            Bootstrap table: Vertical row header overlaps cells as cell content grow
            Asked 2020-Nov-24 at 07:48

            In the first cell of each row I have a header cell with vertically aligned text.

            It is displayed as it is supposed to be with plain HTML + CSS. But when using Bootstrap 4 tables, if one of the cell's content grows and the table row height increases, the vertical header text moves right, towards the other cells, overlapping content. This is not happening when not using Bootstrap.

            Answered 2020-Nov-24 at 07:48

            This happens as long as the rendered height of a cell is more than its width. This is because:

            • Rotating a "tall" rectangle (e.g. 1:2 ratio) by 90deg results in a "wide" rectangle (e.g. 2:1 ratio).
            • The transformation applied to the td elements, rotates them in their current positions without affecting the width and height of the table as a whole.

            This animation should demonstrate this better.

            I imagine the problem would be the same even without Bootstrap as long as the exact same sizes and ratios are replicated.

            One approach to work around this is to wrap the content of the header cells in elements:

            Accessing the wind speed at each turbine
            Asked 2020-Feb-06 at 06:05

            I am looking for a way to access the wind speed in each of my turbines. Even though, as far I am concerned, floris works for only one wind speed as input, you should have a way to be able to see the wind speeds at waked turbines, as you need to calculate it in the end to reach the overall wind farm power. Hence, I went to the documentation and what I could find was that on floris.simulation.farm you have a getter that should be able to return a list of the wind speeds over the wind farm. This can be achieved by:
