Hi
I’m using Ansys CFX V.13 and I need some head start.
I want to simulate wave generated by sliding mass (block). So, I’m supposed to simulate a wedge dropping the calm water surface. The 2-D transient simulation consisting of a wedge prism sliding down an inclined slope of 45°, with translation in the x and y-axis. In order to simulate the wedge falling, I used the Rigid Body Solver in Ansys CFX Pre 13. Noted that the Rigid body is defined as an Immersed Solid with two degree of freedom (x and y-axis). So, I give a density (or mass) to the block and I let it fall under gravity. I have specified a coordinate frame that has its origin at the center of mass of the physical Rigid Body. Another fixed coordinate frame was specified related to the water at rest.
First,
Please, I want to know how to make the block stop moving on the bottom where the potential energy was equal to zero? The velocity of the block was needed to describe the Kinematic of the landslide and it should equal zero in the bottom. In my case, the block passes the bottom wall.
Second, the water still passes through the solid. I already use a very fine mesh.
I would very much appreciate it if you help me solve the following problem.
