1.Non Newtonian Fluids  viscosity does not depend on on the stress state and velocity of the flow. On the other hand the viscosity of non-Newtonian fluids is dependent on shear rate or shear rate history. In Shear thickening non-Newtonian fluid, apparent viscosity increases with increased stress. Such as, Application in Houdini,  In example below, increased pressure make fluid […]

1 Bullet Altering Attributes In fallowing example deforming and in-active bullet object is transformed non-deforming active object. It is done by transferring second objects attributes (box) to bullet object in sopsolver inside dop. 3)object merge, merges animated box with attributes of active=1 deforming=0 4)attribute transfer for point attributes of active and deforming   2 Bullet Constraint […]

1A. Cloth – Pyro Interaction  On default, pyro interacts withj cloth(if pyro solver connected first to merge node). However in this method,  pyro  do not colide but just affect as field force(left example) . In order to have proper colision, cloth obj should be imported with sop solver as colision source. (right example) importing velocity and density from […]
