hi,i'm learning a tutorial about phoenix fd. when i opened the scene file(phx_anti_tank_missile_impact_2016_v002) with 3ds max 2016 and simulated it with phoenix fd 3.1.an error message window jumped out as shown below, i don't know why. can anyone help me? by the way,the other scene file(phx_anti_tank_missile_2016_v001) is OK.

Hello,

Just lower the Grid resolution in the Grid rollout menu. It's set to 56 billion cells and your PC can't handle such a resolution. The other scene has the Grid resolution set to 6 million cells.
