Version 0.6.0a1: First release

Acoustics, flow and heat transfer in one guided workflow.
Licensing with a 30-day trial requested from inside the program.
One .spsim project file holds the settings, the CAD and the results.

[MISSING M43 — owner-approved highlights list for 0.6.0a1]

Experimental

These features run, but their results are not verified yet — treat them as indications:

Compressible flow with the transonic SIMPLE solver
Compressible flow with the pseudo-transient (local time-step) solver
Inlet velocity given as a vector
Insertion loss with a radiation domain at the outlet
Mean-flow convection in the acoustic solve
JCA / JCAL absorbing-material models
Parameter sweeps
Temperature-dependent heat capacity of the gas
