Solve an equation only in a subdomain #46

We would like to be able to solve an equation (Navier-Stokes) only in a subdomain (fluid) or find a way to fix the solution (velocity) at 0 in the other domains.

Apparently doable by specifying the measurement. Would need to do a simple case 2D

RemDelaporteMathurin commented 6 years ago

This is possible by using SubMesh and Measurements defined on this SubMesh. Next Step Do this in 3D
