What is the connection between Icepak and ANSYS?

I can explain it in detail. I have a classmate in avvid company. Icepak was a simplified version of fluent, which was used in engineering, so now icepak uses fluent solver. Fluency belongs to avvid. It seems that fluent was acquired by ansys in 2006, so now the latest version of ansys software package integrates fluent and icepak. Of course, you can also buy an independent icepak. At present, a complete set of ansys software package is almost RMB 3 million, so I don't know if I buy icepak alone. It should be around several hundred thousand! As for learning, if you are engaged in fluid, it is better to choose fluid software such as icepak. The classic ansys software is suitable for thermal stress calculation and some coupled calculations with heat!
