Initial Data

Initial data for the analysis have to be updated in the Initial and Conditional Data window of Tdyn. This window can be opened by selecting Data > Initial Data menu option.

Initial condition is now the corresponding to a fluid moving at a velocity given by the vector (1.0, 1.0, 0.0) m/s. This way Initial Velocity X and Initial Velocity Y fields of the RANSOL page have to be set to 1.0 m/s.

It is also necessary to define the Initial Concentration field of the ADVECT page. This field will be defined for both species with the conditional function:

if(mat(Fluid_Source))then(1)else(0)endif

This function gives a value 1 for Fluid_Source material nodes and 0 for the rest.
