Tutorial 3: Setting up a farm calculation

Introduction

This tutorial will demonstrate the following features:

  • How to set up a wind farm layout with multiple turbines using amrwind-frontend.
  • How to run a parameter sweep over wind speed and wind direction, and have amrwind-frontend generate the necessary input files for each case.

Set some wind properties

For the purposes of demonstrating how to setup a wind farm layout, we'll start with some arbitrary wind speed and wind direction values. The exact values don't really matter, as later on in the tutorial, we'll change these values, but for now they'll be useful when plotting the results.

Below we'll use a wind speed of 10 m/s and wind direction of 225 degrees.

In the ABL tab, set the following inputs according to this table:

Input Value
Use speed & dir instead True
Wind speed 10
Wind direction 225

The input field should look similar to:

images/ABL_settings.png

Then hit the [Calc WS/WDir] button, and it should fill in the values of the Wind Vector appropriately.

Set the simulation type

In the Simulation tab, set the following inputs:

Input Value
Physics models ['FreeStream', 'Actuator']
dt 0.1

images/sim_settings.png

This should set up a case similar to the Tutorial 1 set up.

Create wind farm layout and domain

The first thing to do in setting the wind farm layout is to set the location of each of the turbines. Click on the Farm tab, and hit [show] next to Wind farm turbine layout.

Copy and paste this input into the CSV Contents window.

# CSV file should have columns with
# name, x, y, type, yaw, hubheight, options
T0, 480, 280, UnifCtTest, , ,
T1, 480, 680, UnifCtTest, , ,

If you have all of the turbine inputs in a separate CSV file, you can also load them by hitting [Choose file], then selecting the file, and hitting [Load/Reload].

The other inputs in the

Input value
Farm domain size (X,Y,Z) [960, 960, 960]
Background mesh size [m] 10

images/farm_turbine_layout.png

If you have questions about what each of the columns in the CSV input mean, hit the [?] button. You should see a help window that resembles:

TURBINE LAYOUT SPECIFICATIONS

column description required/optional
name The name of the turbine (can be arbitrary). required
x The x position of the turbine. required
y The y position of the turbine. required
type The turbine type (must be listed under turbine types tab) required
yaw The turbine yaw heading. If not specified, turbine points directly into the wind optional
hubheight The turbine hub-height. If not specified, uses the default from the turbine type optional
options Optional parameters optional

Press the [Preview] button under Actions. It should generate a turbine and domain layout image which resembles something like this:

images/farm_turbine_layout_preview.png

There should be two turbines labeled T1 and T0 in the middle of a 1 km x 1 km domain.

If you want to adjust any turbine positions or orientations, go back and edit the CSV input above. Then press the [Create turbines] button to actually create the turbines in the simulation.

To verify that the turbines are actually created, click the Turbines tab and then look at the Turbine List under Add turbines here. You should see that both T0 and T1 are included in the list:

images/farm_turbine_created.png

The last thing we need to do is set the density global for all of the uniform Ct disks. Click the [show] button next to "Uniform Ct Disk global parameters", and make sure "Density" is set to 1.0:

images/uniformctdisk_density.png

Set the Z boundary conditions

On the horizontal X and Y boundaries, the wind sweep function will automatically set them to be inflow/outflow or periodic depending on the wind direction. However, we need to set the upper and lower Z boundaries to be slip walls (for this uniform flow setup):

Input value
zlo velocity BC slip_wall
zhi velocity BC slip_wall

In the domain tab, click [show] on the "Boundary conditions on Z faces" window, and set the zlo velocity BC and zhi velocity BC to these settings:

images/zlo_zhi_boundary.png

Create wind farm refinement zones

Now around each turbine, we'll add some refinement zones so the turbine rotors can be resolved. Click back on the Farm tab, and hit [show] next to Farm refinement zones.

# CSV file should have columns with
# level, upstream, downstream, lateral, below, above, options
level, upstream, downstream, lateral, below, above, options
0,     1,    1,   1,   0.75, 1,
1,     0.5,  0.5, 0.5, 0.75, 1,

Insert the above CSV text into the CSV Contents box, so the result should look like:

images/farm_refinementspec.png

If you have questions about what each of the CSV columns are supposed to mean, hit the [?] button. You should see a help window with the following information:

REFINEMENT SPECIFICATIONS

column description required/optional
level The mesh level to apply the refinement. required
upstream The number of diameters or meters upstream to apply refinement required
downstream The number of diameters or meters downstream to apply refinement required
lateral The number of diameters or meters off to side of each turbine required
below The number of diameters or meters below the turbine hub-height required
above The number of diameters or meters above the turbine hub-height required
options Any additional options (see below) optional

OPTIONAL INPUTS

keyword default possible values description
orientation winddir winddir, nacdir, x, y Which direction the refinement box should be pointed
units diameter diameter, meter What units the values are in
center turbine turbine, farm Where the center of the refinement zone is located

Press the [Create refinements] button to ceate the refinement zones. Then, to see what the refinement zones look like, open the plot domain dialog on the menu bar: Plot-->Plot domain. You should see that there 4 refinement zones present, and the two previously created turbines also present.

images/plotDomainWin_refinezone.png

Hit [Select all] for both the refinement zones and turbines, then press [Plot Domain]. You should see both turbines plotted, and each refinement level around the turbines shown. Everything should be oriented so that it points into the wind:

images/plotDomainFig_refineturbine.png

Create sampling planes

Now that we have the refinement zones specified, we'd like to add some sampling probes in front of every turbine, and also for the wind farm as a whole.

On the Farm tab, and hit [show] next to Farm sampling. Then copy the following CSV contents into the CSV Contents window.

# CSV file should have columns withturbinescsv=
# name, type, upstream, downstream, lateral, below, above, n1, n2, options
name, type, upstream, downstream, lateral, below, above, n1, n2, options
cl1, centerline, 1,  0, none, none,  none,  11, 11, none
rp1, rotorplane, 2,  0, none, none,  none,  11, 11, none
sw1, streamwise, 2,  1, 1, 0.5,  0.5,  11, 11, usedx:0.25 noffsets:1
hh,  hubheight,400,400,400, 0,  none,  11, 11, usedx:10 units:meter center:farm orientation:x

The result should look similar to this:

images/farm_samplingspec.png

If you have any questions about what the columns in the CSV mean, click on the [?] help button, and it should give you this information:

REFINEMENT SPECIFICATIONS

column description required/optional
level The mesh level to apply the refinement. required
upstream The number of diameters or meters upstream to apply refinement required
downstream The number of diameters or meters downstream to apply refinement required
lateral The number of diameters or meters off to side of each turbine required
below The number of diameters or meters below the turbine hub-height required
above The number of diameters or meters above the turbine hub-height required
options Any additional options (see below) optional

OPTIONAL INPUTS

keyword default possible values description
orientation winddir winddir, nacdir, x, y Which direction the refinement box should be pointed
units diameter diameter, meter What units the values are in
center turbine turbine, farm Where the center of the refinement zone is located

To generate the actual sampling planes, hit the Create sampling probes button under Actions. That should generate 7 sampling planes. To view them, go back to the plot domain dialog on the menu bar: Plot-->Plot domain. This time there should be all of the sampling probe geometries listed, along with the refinement zones, and created turbines as well.

images/plotDomainWin_samplingzone.png

Click on the [Select All] button for each selection window (that will plot all objects in the simulation), and then press the [Plot Domain] button. That will generate an image similar to the one below:

images/plotDomainFig_refineturbinesampling.png

See the output

To see what the AMR-Wind input file would look like, you can go to the menu bar, select Run --> Preview Input File, to see the preview window (you can also just hit File --> Save input file as to save it to a file).

The input file should look similar to:

Set up a wind sweep

The above instructions were to set up a single case with one wind speed (10 m/s) and one wind direction (225) degrees. Now we'll show what happens when you want to vary these to run a parameter sweep. Hit [show] next to Run parameter sweep, and put in the following inputs:

Input Value
Wind speeds 10 20
Wind directions 270 225
Case prefix Tutorial3_Case_{CASENUM}
New dir for each case False
Logfile Tutorial3_logfile.yaml

The set up should be similar to:

images/farm_runsweepspec.png

Then hit the [Create cases] button. Four input files should be generated:

Tutorial3_Case_0.inp
Tutorial3_Case_1.inp
Tutorial3_Case_2.inp
Tutorial3_Case_3.inp

as well as the yaml log file Tutorial3_logfile.yaml which should look similar to this:

Tutorial3_Case_0:
    casename: Tutorial3_Case_0
    WDir: 270.0
    submitted: false
    WS: 10.0
    dir: /gpfs/lcheung/tmp/createdocs/amrwind-frontend/docs/tutorial3
    inputfile: Tutorial3_Case_0.inp

Save the wind farm setup

After doing all of this wind farm setup work, we can save all of these settings so that they can be reloaded and modified for future use.

At the top of the farm tab, expand the Options field and put in the following inputs:

Input Value
Farm setup file Tutorial3_WindFarmSetup.yaml
User comments Tutorial3 wind farm setup parameters.

Note that the user comments field is arbitrary. The input fields should look like:

images/farm_savefarmsetup.png

Then press the [Save YAML] button under Actions. You should see the file Tutorial3_WindFarmSetup.yaml created, which will look similar to this:
