Hello
The subject is a study 2d with a cylinder and the 2 valves. The motion piston is good with dynamic layering zone to represent the mesh regions swept out the moving surfaces or edges in 2D. The motion intake valve is correct until 90° of crank angle, the valve goes down in the cylinder and after 90°, the intake valve goes up and the problem begin. The remeshing parameters are not taken in account at the interface between valve and remeshing chamber and negative volume appear because a node goes up faster than an other one. The time step does change anything. What is the problem ? |
