Long simulation time of interFoam and interDyMFoam; ship hull simulation
 

Hi!

I am simulating a model ship hull with and without ship motion(sinkage+trim); using localEuler and Euler.

Everything works well except the simulation time is quite long. The mesh is about 1.6m but it takes about 1000 ~ 2000 cpu hours to get the final stage I want. The courant number is a big constrain for me: max co = 40 and maxalphaco = 10 is the highest value I can have.

Has anyone did similar simulations or maybe some suggestions?
