optional

This function is used to define a load case on the model. You can only define concentrated or distributed loads on the nodes.

When you use multiple branches in the same CREATE-LOAD function, the load definition works in an additive manner. Each branch will add its contribution to the nodes on which it applies (as showcased in the example).

Name Data Type Data number Optional Default value Physical quantity
MODEL STRING 1 NO
Name of the model on which to create the load case.
NAME STRING 1 NO

optional

This branch is used to add concentrated force and moment vectors on the model nodes. The vectors components must be provided in the global basis.

The force and moment vectors that you provide will be applied on each node of the selection.

#### Keywords

Name Data Type Data number Optional Default value Physical quantity
FORCE FLOAT 3 NO FORCE
Force vector components (global basis) to add on the nodes.
MOMENT FLOAT 3 NO MOMENT
Moment vector components (global basis) to add on the nodes.
ON-NODES-FROM STRING 1 NO

optional

This branch is used to distribute a force vector on the model nodes. The total force vector must be provided, and this force will be distributed on the nodes. You can chose how to distribute the force while providing a weight function. The weight function must be a function of the 3 space variables (x, y and z). And the function must be positive for all the nodes in the selection. SesamX will compute the resulting force vectors that applies on each node of the selection.

The vectors components must be provided in the global basis.

#### Keywords

Name Data Type Data number Optional Default value Physical quantity
KIND ENUM 1 YES NODE
Type of distribution. Currently the only choice is:
NODE to distribute the force directly on the model nodes.
FORCE FLOAT 3 NO FORCE
Total force vector components (global basis) to distribute on the nodes.
WEIGHT-FUNCTION FORMULA 1 NO
The weight function formula (depending on the 3 space variables x, y and z) describing how to distribute the load.
ON-NODES-FROM STRING 1 NO

This example showcases a load case definition relying on 2 CONCENTRATED branches.
