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

+ | ==== CONCENTRATED branch ==== | ||
+ | <label type=" | ||
+ | |||
+ | 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**. | ||

+ | ==== DISTRIBUTED branch ==== | ||
+ | <label type=" | ||
+ | |||
+ | 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. | ||
