Hi 
I am looking at the ansys rocky solver sdk slimulation sequence

https://developer.ansys.com/docs/solver-sdk-2024-r2/solver_hooks.xhtml

If you look at Figure 3.1 and Figure 3.2, I do not see anywhere the function named as ROCKY_PLUGIN_COMPUTE_JOINT_FORCES

so I am wondering at what step in Figure 3.1 is this function execuited in rocky? Please let me know

Hello, Shyam. I hope you are doing well.

A module implementing a joint model must provide necessarily the force and the moment acting at a joint.
This allows Rocky to sum those forces and moments to the forces and moments acting on the elements associated to the joint.
Therefore, you have to place the function at a point where forces have already been computed.

You can place the function after ROCKY_PLUGIN_TEAR_DOWN_CUDA(), at the end of your code.

If you are an Ansys Customer, I strongly encourage you to download Rocky's additional package, where you will find Solver SDK examples that may greatly help you in developing custom codes for Rocky.

Also, check the public tutorial about Solver SDK usage: Tutorial 23

Best regards,
Lucas.
