How to add aggregates to concrete's model

Please login with a confirmed email address before reporting spam

Hi,

I would like to model the inside of a small concrete parallelepiped to perform a mathematical estimate with comsol on water absorption. I would like to insert aggregates within it as spherical particles of variable diameter. The literature talks of a distribution with a Fuller curve with decreasing diameters. There are a few references in the literature, but not to how to do it. In this regard, for ending, I only found a YouTube video about that in a somewhat approximate way, that is, by creating a method and modifying the syntax of the code somehow.

Is this the solution to move forward? If not, does anyone have any ideas? Does someone advice to me better to use an external mesher?

Thank you.

Hello Simone,

We have a blog post on how to write a script to generate a randomized geometry similar to yours.

Best regards,

Jeff
