m zubair is on a distinguished road
Can anybody tells how to solve this issue?
I want to move the solid body having certain mass by giving inlet pressure of air 6bar, through water zone but body moves toward left side instead of going upward when I run the simulation in the first time step.
My settings are as fallow
Transient, g=-9.81, axisymmetric.
VOF model on with implicit body force. K-epslon model on
Fluid mixture is water and air, define the water as secondary phase.
Pressure inlet is 6bar of air.
Smoothing and remeshing are turned on, six dof on, created the body having mass 500kg and moment of inertial values are all set to zero. Define the solid body as rigid body motion having Center of gravity (0,0).
Hybrid initialization, time set size 0.0003
But the negative cell volume comes as in figure you can see body have moved toward left but it should move in vertical upward direction , please suggest me what to do.
