winc3d's Introduction

Description

WInc3D provides an integrated wind farm simulation framework that allows detailed analyses of wake–to–wake and turbine–to–wake interactions. The code is built upon the high–order finite difference numerical solver incompact3D (Laizet and Lamballais, 2009) which makes use of an efficient 2D domain decomposition algorithm (Laizet and Li, 2011) that allows the code to scale on up to O(10$^5$) computational cores. WInc3D offers a number of built-in models, including a native actuator line model (ALM). The models have been validated using both wind tunnel data (Deskos et al 2020) and supervisory control and data acquisition (SCADA) measurements from a utility–scale offshore wind farm (Deskos et al 2020)

mpirun has exited due to process rank 1 with PID 6378 on
node liu-Precision-Tower-7910 exiting improperly. There are two reasons this could occur:

  1. this process did not call "init" before exiting, but others in
    the job did. This can cause a job to hang indefinitely while it waits
    for all processes to call "init". By rule, if one process calls "init",
    then ALL processes must call "init" prior to termination.

  2. this process called "init", but exited without calling "finalize".
    By rule, all processes that call "init" MUST call "finalize" prior to
    exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Pitch and twist

It would be great to have pitch and twist as separated variables, specially to do control

Bug with rotation velocity

I get a small difference when I compute (omega x r) from the radial position and from the flow angle in the output files of the turbine.

I guess there is some small bug between nodes and elements somewhere

thrust computation

The thrust is computed as the sum of all the forces but it should only account for out-of-planes ones.
