New question #702418 on Yade: https://answers.launchpad.net/yade/+question/702418
Hi, I am doing fluid-solid coupling simulation of a cylinder.In the lab,I first apply a fixed confining pressure, and then carry out axial loading while maintaining the osmotic pressure in the longitudinal direction (z direction) until failure.So I want to do the same thing in simulation. I read the explanation in [1] about flow.bndCondIsPressure and flow.bndCondValue,but I have some doubts about the setting of these two values. 1)flow.bndCondIsPressure:defines the type of boundary condition for each side. True if pressure is imposed, False for no-flux. As I described above,there is osmotic pressure only in the Z direction. More specifically, it is only applied in the positive direction of the Z axis. Measure the permeability from the other end. Can it be set to =[0,0,0,0,0,1] or [1,1,1,1,1,1] 2)flow.bndCondValue:Imposed value of a boundary condition. Only applies if the boundary condition is imposed pressure, else the imposed flux is always zero presently.Ditto, I set it as =[0,0,0,0,0,P], is it reasonable? Cheers everyone.
