Yes, Ziva VFX can handle multiple solvers in a single scene. However, when there is only one solver in a scene, Ziva commands will always use that solver. However, if there is more than one solver in a scene, Ziva commands will attempt to choose a solver based on the following logic:
Top priority is given to solver nodes that are selected directly. Selecting a solver’s cache node is equivalent to selecting the solver node.
Next, solver nodes connected to selected simulation objects are considered.
Finally, the Default Solver is chosen, which can be set with Set Default.
If the ambiguity between multiple solvers cannot be resolved, an error message is printed. Examples of unresolvable ambiguity include:
Multiple solver nodes/caches in the selection.
Simulation bodies from multiple solvers in the selection.
No Default Solver has been set.
