Omnis turbocompressor tutorial: Initial solution error

Johan M · February 14, 2022, 03:25

Hi everyone

I had been doing the turbocompressor tutorial from the Omnis user guide. I had encountered a ''Cannot compute initial turbomachinery solution'' error when trying to run the simulation, seen attached.

I have checked the initial conditions against the user guide values several times but have still bee unable to spot the error. I would appreciate any assistance

regards
Johan

Dear Johan,

Can you check if the correct mesh is selected under the 'Choices' for each domain?
Are you able to run the computation by using a constant initial solution instead?
It could also be that the wrong type of boundary condition is chosen for the inlet and the outlet.

Regards,
Karthik

Dear skarthik,

Thank you for the reply. I have checked the first suggestion you mentioned and it is indeed the correct mesh. I will try the later two suggestions out

kind regards
Johan
