clump cfd attribute command

Syntax

clump cfd attribute keyword ... <range>

Primary keywords:

force    porosity

Set the value of clump CFD attributes. This command is a synonym for the clump cfd initialize command. Individual attributes can be listed with the clump cfd list command, and all clump CFD attributes can be visualized.

force v <keyword>

Force applied by fluid to the clump or the drag force.

add f

Add f to the existing value.

gradient v

Apply a linear gradient in each of the axes directions starting at the origin.

gradient-x f

Apply a linear gradient in the \(x\)-direction starting at the origin.

gradient-y f

Apply a linear gradient in the \(y\)-direction starting at the origin.

gradient-z f

Apply a linear gradient in the \(z\)-direction starting at the origin.

multiply f

Multiply the existing value by f.

replace f

Replace the existing value with f.

porosity b

Porosity contribution mode. If true (the default), the clump contributes to the porosity of the CFD element associated with it.
