Before revision:  The idea is to adopt two different proceduresand apply them to the same test case . First we preform a reduction technique that is based on a monolithic procedure , where we therefore solve all at once the fluid and the solid problem.
After revision:  The idea is to adopt two different proceduresand apply them to the same test case of interest. We first implement a reduction technique that is based on a monolithic procedure , where we therefore solve all at once the fluid and the solid problem.
