Good afternoon with everyone. I am doing a scientific investigation for my university, and I was trying so hard but my transient simulation of pelton turbine does not run. Does anyone know any guide where I can see where I am doing wrong? or maybe someone can explain to me how to proceed with it?
Thanks for all |

It is best to provide more informations for us about your general setup, mesh and eventually error warnings of the solver when it crashes.
Also, have a look at the CFX Tutorials. The tutorial "Flow in an axial turbine stage" provides information for transient simulations. Have a look at it, too. |

Hi, thanks and maybe, do you have some guide to obtain a fine mesh for my geometries?

Thanks and maybe, Do you have any tutorial or guidebook to obtain a fine mesh of my computational domain?

Read the CFX documentation on obtaining convergence, also the FAQs on the forum: https://www.cfd-online.com/Wiki/Ansys_FAQ
Note that a finer mesh usually is harder to converge, not easier. But a higher quality mesh will definitely help. How do you do a high quality mesh? Do the tutorials on your meshing software.

You said that your transient simulations didn't run. Do they run now or even start ? If not, how about your steady-state simulations ? Any errors there ?
