Geometry primitives - Background Mesh Box and Material point not found

I can’t see the ‘Background mesh’ and ‘Material point’.
How can i fix it…?? or what am i missing…?

Hi, this is Fillia.

The Background Mesh Box and the Material Point are only used as settings of the Hex dominant parametric algorithm. Right now you are using the Standard mesher, so you will not have to set these two.

For more information regarding this algorithm, have a look here:

Best regards,

i used standard mesh also this link,(same model/condition) but it had Background Mesh and Material Point. don’t this matter??

No, these are only necessary when using the Hex dominant parametric algorithm, so they are present by default. When using the Standard mesher, there is no need to add them.
