i am new to this simulation process and this is my first attempt with a model drawn by me by referring to a journal .
JOURNAL LINK : https://doi.org/10.1016/j.jestch.2018.05.016
i am doing this simulation setup for validation purpose,so that i could say (in my project presentation at university that) i can do a simulation regarding this topic and i can generate results for a new model which i will be drawn by modifying certain values or changing certain parameters of the given turbine model…in short, i need correct results. (which is little difficult for me as i am new to this).
while i was doing my simulation, i got an error saying “A setup with 2 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to them.”…i looked in forums , but in vain i couldn’t do much. I couldnt understand.
As i mentioned above, i have put the values of simulation setup by referring the journal.I watched some of the webinars of simscale and i tried the example of francis turbine. So that values or datas i didnt got; i have adjusted with the setup of this francis turbine setup. ( Fluid Flow Through a Water Turbine | Tutorial | SimScale )
project link: https://www.simscale.com/workbench/?pid=4647100771582061026&mi=spec%3A251c19b7-81a9-4bc7-b63c-1a79a5d868b7%2Cservice%3ASIMULATION%2Cstrategy%3A202
Moreover i needed help in doing this simulation ,so that input values i put into this setup are correct and have some reason behind those steps ( as all the minor details of the simulation is not fully given in the journal ).
one more thing that i would like to say is that, the blade cross section is of the shape of an airfoil ,named NACA0021 ( i browsed for NACA0020 ,but couldnt get it).The naca foil i have drawn is not by importing the coordinates from a csv file (as my pc showed error in doing that), so instead i traced the airfoil ( from image or canvas) and modelled using Fusion 360.
before importing the model ,i have combined different bodies of the turbine (blade,shaft,hub) into one body.
please do help…i dont have much time left for the submition
thanks a lot for the effort for reading this out.
