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 ?
