Hi all. My task is to calculate a multistage centrifugal pump (pressure, efficiency, etc.):

Counting one wheel is not a problem. My pump consists of 100 wheels. This will require >1000 cores of computing power. There are no such capacities. Please tell me what the UDF script will be for solving one wheel, which will record data and transmit it to the next wheel? This way I can read each wheel in turn, transferring data from one to the next. Thank you.

Hello, 

I would suggest decomposing your domain into smaller ones, 1 to several wheels depending on your capacity. You can then export the outlet of each domain and read them as a profile for the subsequent inlet.

Thank you I will try

I looked thanks.

Tell me, when calculating wheels, what fields need to be passed? Speed and pressure are accurate. And what else?

My goal is to ultimately monitor the pump’s pressure characteristics, efficiency and cavitation.

I will model one wheel. There will be a rotating domain around the wheel. The two faces of this domain will be the input and output of the wheel, where I will substitute the fields.
