What is the parameter b?

Text: Constant 'b' cannot be zero. 'b' is zero when fluid height is zero (or fluid particles were not created).

The constant b is used in the equation of state: https://github.com/DualSPHysics/DualSPHysics/wiki/3.-SPH-formulation#34-equation-of-state.

By default it is calculated automatically, but in case that there is no fluid in the domain, it is 0 as said in that message. Therefore, in case you want to simulate fluid, check your definition. Otherwise, in case you want a case without fluid, impose a value for constant b in the section constants definition.
