How to calculate non-cavitatiuon using openfoam
 
hi! everyone

i want to calculate non-cavitation in LES,

when i calculate the cavittaion condition i use the interPhaseChangeFoam,but i don't know how to calculate non-cavitation in LES

can anyone give me some suggestions?

best wishes!

Just use a solver that doesnt model cavitation... rhoCentralFoam? pimpleFoam?

hi! Santiago

thanks for your reply。

i use two ways to calculate non-cavitation,

the first one is set the cavitation number to a high level,also use the interPhaseChangeFoam, and it seems work well now.

the second way is use the pimplefoam to calculate non-cavitation,but it semms caluculate too slow, i am trying to solve this problem
