Hello Salek, 

You can assign new material in Discovery Model model as well. You do not need to be in Explore mode to add/edit materials. 

Discovery by default assigns Structural steel to your geometry. You can add/edit material by triple clicking the object or by selecting the object direclty from the model tree. 

For Explore mode to work, you need minimum 4GB dedicated GPU RAM, while 8GB GPU is recommended. Please refer Ansys Discovery Hardware Requirements (2022 R2) - Ansys Knowledge for more information.

Thanks & Regards,
